The process of straightening an unsaturated fatty acid to create a more solid fat that resists rancidity is called
Answer:
The correct answer is hydrogenation
Explanation:
The process of straightening an unsaturated fatty to produce more saturated and more solid fat is called hydrogenation. In the process of hydrogenation, the hydrogen is added to the liquid unsaturated fats to convert them into solid fat.
Hydrogenation helps in increasing the shelf life of the oil by resisting rancidity. Most of the trans fat in our diet is made from the process of hydrogenation. Fully hydrogenated oil contains a very small amount of trans fat and is better than trans fat which is partially hydrogenated.
Answer:
Hydrogenation.
Explanation:
Two main types of fatty acid are unsaturated fatty acid and saturated fatty acid. The saturated fatty acid has single bond in their structure whereas unsaturated fatty acid has double or triple bond.
The hydrogenation may be defined as the addition of hydrogen molecules to the unsaturated fatty acids that makes them saturated. This process in the presence of palladium that acts as catalyst for the reaction. The increases in saturation level decreases the rancidity as well.
Thus, the answer is hydrogenation.
The human stress system evolved to deal with events such as getting chased by a lion. Which modern stress activates the stress system in the same way as getting chased by a lion?
Final answer:
Modern stressors like public speaking or deadlines trigger the fight or flight response similar to ancestral threats like being chased by a lion. This chronic activation of the stress system can lead to serious health issues.
Explanation:
The modern stress that activates the stress system in the same way as getting chased by a lion would be psychological threats, such as public speaking or facing a looming deadline. These modern stressors activate the fight or flight response, which the human nervous system has evolved over millions of years to handle immediate physical threats. The autonomic nervous system triggers a series of hormonal and physiological adjustments when faced with such stress. Unfortunately, modern stressors tend to be prolonged and can lead to chronic activation of this system, which can have serious health consequences, including cardiovascular disease, diabetes, anxiety disorders, depression, and impaired judgment.
A grasshopper jumps along a line. His first jump takes him 1 cm., the second 2 cm, etc. Each jump can take him to the right or to the left. Prove that after 2017 jumps, the grasshopper cannot be in the same location it started.
Answer:
The grasshopper cannot be in the same location it started because by 2017, it would have covered a distance of 1017576.5 to either left or right. and that distance is not an integer.
Explanation:
The grasshopper jumps in integer of 1 cm to either right or left
Calculating for the total distance covered in 2017 jumps
Total Distance = (2017 x 2018)/2 = 2035153 cm
To either right or left: this implies that the total distance be divided by 2
=> 1017576.5 cm
It shows that at some point, the grasshopper will not be in a position of integer on either right or left.
Therefore, it can not get to its initial point of start.
To prove that after 2017 jumps the grasshopper cannot be in the same location it started, we can calculate the total distance covered by the grasshopper. By using the formula for the sum of an arithmetic series, we find that the grasshopper would have covered a total distance of 2036171 cm after 2017 jumps. Therefore, the grasshopper cannot be in the same location it started.
Explanation:To prove that after 2017 jumps the grasshopper cannot be in the same location it started, we need to consider the distance covered by each jump. The grasshopper jumps 1 cm in the first jump, 2 cm in the second, and so on. We can observe that the distance covered in each jump is increasing by 1 cm. Therefore, after 2017 jumps, the grasshopper would have covered a total distance of 1 + 2 + 3 + ... + 2017 cm.
To find this total distance, we can use the formula for the sum of an arithmetic series: S_n = (n/2) * (a_1 + a_n), where S_n is the sum of the first n terms, a_1 is the first term, and a_n is the nth term. In this case, n = 2017, a_1 = 1, and a_n = 2017.
Substituting these values into the formula, we get S_n = (2017/2) * (1 + 2017) = 2017/2 * 2018 = 2036171 cm.
Based on this calculation, we can conclude that after 2017 jumps, the grasshopper would have covered a total distance of 2036171 cm. Since this distance is greater than zero, it is impossible for the grasshopper to be in the same location it started.
A patient was exposed to a nerve gas during a chemical warfare attack. The nerve gas inhibited the enzyme acetylcholinesterase. What will happen to the amount of acetylcholine in the synaptic cleft
Explanation:
When ACh is consistently released from the synaptic vesicles into the synaptic split, an expansion in transmitter fixation follows. The serine hydrolase AChE causes a fast hydrolysis of ACh with an exceptionally high response rate prompting the breakdown of ACh and its disposal from the synaptic separatedThis response drastically diminishes the grouping of ACh inside the synaptic split. In this manner, ACh focus rots because of hydrolysis, dissemination and connection to AChR in an exponential fashionWhat are the disadvantages of a flatworms digestive system having
The provided question is incomplete, however the complete question is as follows:
What are the disadvantages of a flatworm's digestive system having only one opening?
Answer:
The correct answer is - cannot consume food continuously .
Explanation:
The main disadvantage of digestive system in the flatworm are one way of opening which is a characteristic feature of many Platyhelminthes phylum organism. This type of digestive system where food enters and exits with the same and only opening available.
In flatworms, once the organism take the food it has to wait for the food to be digested and excreted out by the same opening it use to eat and leave the same opening.
Thus, the correct answer is - cannot consume food continuously.
The question is incomplete. The complete question is as follows:
What are the disadvantages of a flatworm's digestive system having only one opening?
Answer:
The digestive system of the flatworms has been modified depending on their host parasite interaction. They have simple digestive system with the single opening.
This digestive system might have some disadvantages as the food consumption is not continuous due to the single opening. The ingestion and excretion as same opening and this increases the timing of the digestion and excretion process. The energy is expanded more in this type of the digestive system.
Which type of epithelium lines the inferior portions of the pharynx?
Answer:
The type of epithelium that lines the inferior portions of the pharynx is stratified squamous epithelium.
Explanation:
The pharynx is a structure made up of muscles and mucous membranes -like many internal organs- that is part of the respiratory system and is an intermediate step in the digestive tract.
This structure has two portions:
Upper or nasopharynx Lower, or oropharynx, in contact with the airways.Some even propose that the borderline surface between the pharynx and larynx can be called the laryngopharynx, due to its tissue structure.
The lower portion of the pharynx is covered by a squamous stratified epithelium, the inner layers of which rest on a basal lamina. The more superficial layers provide protection to the interior of the pharynx against friction, in addition to remaining lubricated by mucous secretion at that level.

During a party, Michael was talking to a friend about the symbolism involved in a recent movie. Michael attributed the explanation of the symbolism to a prominent movie critic, when actually he heard it from his roommate. This example illustrates which of the following phenomena?a. Source-monitoring error
b. Serial position effect
c. Cryptomnesia
d. Amnesia
Answer:
a. Source-monitoring error
Explanation:
Source-monitoring error is a phenomenon that refers to a type of memory error in which an individual’s recall of a memory or experience is disrupted leading to incorrect attribution of an experience to an incorrect source. Several factors have been identified to be the cause of this memory error. They include, brain injury, amnesia, depression, aging, high stress level, etc.
Answer:
A. Source-monitoring error.
Explanation:
Source monitoring errors occur when normal memory recall and perceptual processes are disrupted and a memory error occurs. Source monitoring itself is an unconscious mental test that humans perform in order to determine if a memory is "real" and accurate as opposed to being from an extraneous source like a dream or a movie. People use many sources to determine the source of a memory or idea. When a disruption in source monitoring occurs errors in recall can result as a source monitoring error. These occur when a specific recalled experience is falsely attributed to be the source of a particular memory.
In this instance now, Michael was talking to someone about symbolism in a recent movie. Instead of Michael to attributes the explanation to his roommate that told him, he attributed the explanation to a prominent movie critic.
When sperm and egg cells undergo meiosis, the number of chromosomes goes from ______ to _______. When an egg is fertilized by a sperm cell that number goes from ______ to ______. 2 to 2; 1 to 1 1 to 1; 2 to 2 1 to 2; 2 to 1 2 to 1; 1 to 2
Final answer:
The number of chromosomes in sperm and egg cells goes from diploid (46) to haploid (23) during meiosis. Upon fertilization, these haploid cells merge to form a diploid zygote with 46 chromosomes. The correct sequence is 2 to 1; 1 to 2.
Explanation:
When sperm and egg cells undergo meiosis, the number of chromosomes goes from diploid (2n) to haploid (n). Specifically, the number goes from 46 to 23 chromosomes in humans. When an egg is fertilized by a sperm cell, this number goes from haploid to diploid, or from n to 2n, effectively from 23 to 46 chromosomes. Therefore, the correct sequence of numbers from the options provided is 2 to 1; 1 to 2.
During this process, DNA is copied once, and then the cell divides twice, leading to gametes with half as much genetic information as the original cell. Upon fertilization, the gametes unite and the original number of chromosomes is restored in the zygote, which now contains the full complement of genetic information necessary for the development of a new organism.
Adult male humans generally have deeper voices than do adult female humans, which is the direct result of higher levels of testosterone causing growth of the larynx. If the fossil records of apes and humans alike show a trend toward decreasing larynx size in adult females and increasing larynx size in adult males, then _________.a. sexual dimorphism was developing over time in these speciesb. intrasexual selection seems to have occurredc. stabilizing selection was occurring in these species concerning larynx sized. selection was acting more directly upon genotype than upon phenotype
Answer:
a. sexual dimorphism was developing over time in these species
Explanation:
Sexual dimorphism is an evolutionary change that occurs over time in species, which could be as a result of sexual selection which makes both sex of a species develop a systematic difference in form, which can manifest in terms of body size, color, secondary sex characteristics, and size of some structures such as larynx size which accounts for deeper voices in males in relation to levels of testosterone. This is later passed across from generation to generation over time.
Which of the following is the earliest step in transcription? A. RNA polymerase encounters a termination signal, and the DNA molecule is released. B. Complementary RNA nucleotides are synthesized and added to the mRNA molecule. C. Introns are excised from the pre-mRNA strand. D. RNA polymerase binds to the promoter on the template strand of DNA.
Answer:
D.
Explanation:
Transcription is the first step in gene expression. It involves duplicating a gene's DNA sequence to make an RNA molecule.
It is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template)
Answer: D. RNA polymerase binds to the promoter on the template strand of DNA.
Explanation: The first step in transcription is termed initiation step. In this step, the enzyme RNA polymerase binds to a region or section of a gene called the promoter. This specific action results to the signalling of the DNA to unwind so the enzyme can decode the bases in the DNA strands. The enzyme now make a strand of mRNA with contemporary bases.

Answer:
d) seborrhea, a disease characterized by red, itchy lesions on the scalp.
Explanation:
Sebaceous gland are the glands which are usually present beneath the skin and with the hair follicles. They are also known as oil-producing glands as they released sebum.
If the sebaceous gland becomes too active and secrete extra sebum than it can cause a condition called Seborrhoea. In Seborrhoea microbe like Malassezia fungi species colonizes the area where sebum is produced and initiates local inflammatory response which causes scaly patches, itchy lesions, and red skin. So the correct answer is d.
Overactive sebaceous glands primarily cause seborrhea, which is characterized by red, itchy lesions on the scalp. The glands produce excessive sebum resulting in this condition, while options a, b, and c are not direct consequences of overactive sebaceous glands.
Explanation:Overactive sebaceous glands in the skin can lead to various outcomes, but the most corresponding answer to this question is option d) seborrhea, a disease characterized by red, itchy lesions on the scalp. The sebaceous glands produce an oily substance called sebum, which plays a critical role in the protection and nourishment of skin. However, when these glands become overactive, they generate excessive amounts of sebum. This excess sebum can result in a condition known as seborrhea, displaying symptoms of redness, itchiness, and flaky skin particularly on the scalp. Options a, b, and c are not direct effects of overactive sebaceous glands.

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of stomata.e. the light reactions.
Answer:
A) photorespiration.
Explanation:
Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.
The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.
The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.
Thus, Option-A is correct.

Explanation:
Brian was not aware of that fact that the horse is incapable of breeding at the point he buys it, but Larson assures Brian the horse is healthy. In this light, if Brian sues to cancel the contract with Larson, the court will allow it based on a mistake of fact. This way the court will reduce any civil liability or criminal culpability because Larson might not know that the horse cannot breed, although he is certain that the horse is healthyHence, the right answer is "Likely that a court will allow the rescission based on a mistake of fact"The sensory receptors of the inner ear for equilibrium are
The inner ear structures responsible for equilibrium are the utricle, saccule, and three semicircular canals. They contain hair cells with stereocilia that sense head position and movement. Signals from these structures reach the brain stem and cerebellum via the vestibulocochlear nerve.
Explanation:The sensory receptors of the inner ear responsible for equilibrium, or balance, are primarily located within the vestibule of the inner ear. Specific structures involved are the utricle, saccule, and the three semicircular canals.
Each of these structures plays a distinctive role in maintaining equilibrium: the utricle and saccule help sense head position, while the semicircular canals sense head movement. They contain mechanoreceptors, specifically hair cells with stereocilia, that sense your body's position and motion and send this information to the brain.
The sensory signals generated in these structures are transmitted to the brain via the vestibulocochlear nerve, eventually reaching the brain stem and cerebellum, thereby allowing you to maintain balance and orientation.

Q. A person’s blood glucose level fluctuates during the day, asrepresented in Figure 1. Two hormones, insulin and glucagon,are directly involved in regulating the blood glucose level tomaintain a healthy level. Insulin acts to lower the blood glucoselevel, and glucagon acts to increase the blood glucose level.Which of the following best predicts what will happen to theblood glucose level if the person has another meal at 5 pm?Immediately after the meal, the blood Immediately after the meal. the blood. glucose level will decrease because of the . glucose level will increase, and then insulinincrease in glucagon levels. will be secreted to counter the increase.Several hours after the meal, the blood The blood glucose level Will not change after. . the 5 pm. meal because the person hasglucose level wull Increase sharply because of. . . . already consumed two meals and the bloodan Increase In the amount of glucagon .secreted glucose level has been adjusted to a steady.' state level.
Answer:
If the person has another meal after 5 pm, the glucose level in the blood will increase, and the insulin level too.
Several hours after the meal, the glucose levels will decrease, and the glucagon levels will increase.
Explanation:
When a person ingests another meal after 5 p.m, the glucose levels in the blood will increase, as the body does not need all that glucose right now the insulin levels in the blood will increase to store glucose for later. The glucagon levels after a meal are very low because the aim is to store glucose not use it.
Several hours after the meal, the body needs the energy to keep operating so it will use the glucose that was stored, to do this, the levels of glucagon in blood have to increase and release the glucose, and the levels of insulin in blood have to decrease.
Following a meal, blood glucose levels rise which triggers the production of insulin. Insulin helps in glucose absorption and reduces the blood glucose level. Several hours post-meal, as glucose levels drop, glucagon gets released which assists in raising the blood glucose level by promoting glycogen breakdown and gluconeogenesis.
Explanation:When a person has a meal, the glucose level in the blood increases. This is due to the carbohydrates in the food being broken down into glucose. This rise in glucose triggers the pancreas to produce and release insulin. Insulin aids the cells in absorbing glucose and regulating the blood glucose level by reducing it. Moreover, insulin stimulates the liver and muscles to store excess glucose as glycogen.
Several hours after the meal, as the glucose is utilized, blood glucose levels start to drop. This decrease signals the pancreas to release glucagon. Glucagon stimulates the liver to break down the stored glycogen into glucose and release it back into the blood, thereby increasing the blood glucose level. Additionally, glucagon promotes the process of gluconeogenesis in the liver, where it synthesizes glucose from amino acids absorbed from the bloodstream. Both of these actions mediated by glucagon result in an increase in blood glucose levels to maintain it at a steady state.
In conclusion, immediately after a meal, the blood glucose level will increase and then insulin will be secreted to counter the increase. Then several hours after the meal, the blood glucose level will increase again due to an increase in the amount of glucagon secreted.

Final answer:
Maureen should become more self-conscious (B), aware of her actions and their consequences, and develop an internal locus of control to take responsibility for her behavior, enhancing her conscientiousness.
Explanation:
In order for Maureen to take responsibility for her behavior, she needs to become more self-conscious. This means she should be more aware of her own actions and their impact, as well as develop an ability to reflect on her behavior. For example, instead of blaming others for her bad grades, like Jane with an external locus of control, Maureen could develop an internal locus of control where she recognizes her role in her academic performance. Developing conscientiousness is also key, as it involves being punctual, following rules, working hard, and being decisive—all traits that support taking personal responsibility.
Although the mechanisms by which aerobic training leads to enhanced aerobic performance in adolescents are still unclear, it is likely that ________________ may play a role.
Answer:
increased maximal stroke volume
Explanation:
Stroke volume is the amount of blood put out by the left ventricle during a contraction. By doing the regular aerobic training one can increase its maximal stroke volume. More the stroke volume of a person less will be its heart rate because more amount of blood will be pumped by the heart in a single time.
This is the reason why athletes have a decreased heart rate than normal people. So till now the mechanism of enhanced aerobic performance lead by aerobic training is not clear but it can be said that increased maximal stroke volume may play a role.

Explanation:
In a winter of an epidemic flu, 2000 babies were surveyed by a well-known pharmaceutical company to determine if the company's new medicine was effective after two days. Among 120 babies who had the flu and were given the medicine, 29 were cured within two days. Among 280 babies who had the flu but were not given the medicine, 56 were cured within two days. Is there any significant indication that supports the company's claim of the effectiveness of the medicine?
Final answer:
A preliminary comparison of cure rates indicates a slight advantage for the medicated group over the non-medicated group, but statistical analysis is required to determine significance. The medicine's goal is to manage symptoms, as complete prevention is not typically achievable with current antivirals like oseltamivir.
Explanation:
To assess the effectiveness of the pharmaceutical company's new flu medicine, we can compare the cure rates between the group that received the medicine and the group that did not. In the medicated group, 29 out of 120 babies were cured within two days, giving us a cure rate of approximately 24.2%. In contrast, the non-medicated group saw 56 out of 280 babies cured, which translates to a cure rate of around 20%.
While there is a numerical difference between the cure rates of the two groups, to determine if this difference is statistically significant, a hypothesis test such as Chi-square or Fisher's exact test would usually be conducted. These tests would provide a p-value that, when compared against a chosen significance level (commonly 0.05), would indicate whether the observed difference in cure rates could be due to chance or if it is statistically significant. However, without further statistical analysis, we cannot make a definitive conclusion on the effectiveness of the medicine.
It is also important to note that antivirals like oseltamivir and other medications prescribed for flu symptoms work to reduce symptom duration and inhibit the spread of virus but are not curative. They are part of the recommended treatment protocols for managing flu symptoms along with prophylactic antimicrobials and over-the-counter drugs to alleviate fever and headache.
