What are human mutations?A genetic mutation is a change in a gene's DNA sequence that results in something different. It permanently alters the DNA sequence of that gene. Genetic differences are necessary for people to develop, which is the process of change across generations. A random genetic mutation arises in a single person.
Depending on their context or location, mutational impacts might be helpful, detrimental, or neutral. The vast majority of non-neutral mutations are harmful. In general, the greater the number of base pairs impacted by a mutation, the greater the effect of the mutation and the greater the risk of the mutation being detrimental.

One of your brother's friends, Dylan, is unusually short with a stocky build; has a flat face, a large tongue, and an extra fold of skin on his eyelids; and suffers from cognitive deficits, hearing impairments, and a heart defect. Dylan likely has __________.
Answer:
Dylan likely has Down Syndrome / 21 Trisomy Syndrome.
Explanation:
Down Syndrome is a genetic disorder in which the person has an extra copy of chromosome 21, this is why the disorder is known as Trisomy 21. This extra copy changes how the body and the brain develope, which can cause mental and physical problems.
Children with this disorder usually have a low intellectual level, the most frequent cause of identifying mental delay of genetic origin.
Some of the characteristics of these children are slight diminution in the skull size, almond-shaped eyes, a short neck, small ears, a small mouth, a large tongue tends to get out of the mouth, narrow auditive conduct, tiny hands, and feet, weak muscular tone, and they are usually short in height.
There are also some medical problems such as hearing loss, apnea, ear infections, ocular problems, heart defects, intestinal malformations, hypothyroidism, hip dislocation, anemia, among others.
One way scientists hope to use the recent knowledge gained about noncoding RNAs lies with the possibilities for their use in medicine. Of the following scenarios for future research, which would you expect to gain most from RNAs? A) exploring a way to turn on the expression of pseudogenes B) targeting siRNAs to disable the expression of an allele associated with autosomal recessive disease C) targeting siRNAs to disable the expression of an allele associated with autosomal dominant disease D) creating knock-out organisms that can be useful for pharmaceutical drug design E) looking for a way to prevent viral DNA from causing infection in humans
Answer:
C) targeting siRNAs to disable the expression of an allele associated with autosomal dominant disease
Explanation:
siRNAs are the small interfering RNAs that do not serve as a template during the process of protein synthesis. These RNA molecules are double-stranded and have about 23 nucleotides in total. siRNAs control the expression of genes that selectively inhibiting the mRNAs. They control gene expression at the post-transcriptional level by selectively cleaving mRNA molecules that have the nucleotide sequences complementary to the siRNA.
The siRNA molecules can be used to selectively inhibit the expression of the allele for an autosomal dominant disorder. This selective inactivation of the allele associated with the disease would help to control the corresponding genetic disorder.
For children with two myopic parents, the likelihood of becoming myopia is _____ correlated with the number of hours spent playing sports each week.
Answer:
The answer is incomplete
Explanation:
However, there is no correlation between parents who have myopia and there children contacting such by playing sports each week regardless of time spent.
Myopia also known as shortsightedness is a condition in which the eyes can see clearly objects that are close but objects that are far appear blurry. Myopia occurs when the shape of the eye causes light rays to bend incorrectly causing images to be formed in front of the retina instead of been formed on it. Myopia is not a sex-linked character unlike colour blindness and is neither a condition that is always passed on to the offspring by parent(s) but there are cases in which parent(s) pass this condition to there offspring(s).
Myopia can however be caused by genetic factors coupled with several environmental factors and life choices like foods eaten, watching of movies in the dark etc.
Water is able to maintain the temperature of living organisms, keeping them from freezing or overheating. This is because water has a:____________
Answer:
High specific heat.
Explanation:
Water is able to maintain the temperature of living organisms because it has highest specific heat. Specific heat is a physical property of matter. If specific heat is high then the matter does not get heated easily but once it is heated it does not cool down easily either. In short we can say that water can easily resist temperature changes because it has very high specific heat. This property plays a great role in maintaining the temperature of a living organism's body because all organisms have water in their body. When heat is generated within the body, it is unable to disrupt internal temperature of the organism's body because the water does not get heated easily as a result of which the temperature of the body does not rise. On the other hand, the internal temperature of the body remains the same with slight decrease in the temperature outside because water does not radiate heat easily either. This is how high specific heat of water helps in maintaining a constant temperature in the body of organisms.

The role of central nervous system activity for the experience of pain is best highlighted by:_______.
a) prosopagnosia.
b) phantom limb sensations.
c) frequency theory.
d) perceptual adaptation.
e) the opponent-process theory.
Answer:
b) phantom limb sensations.
Explanation:
This is the experience of sensation and pain from limbs that no longer exist.It is a psychological problem which originated in the brain and spinal cord of Amputees.
The sensations disappeared naturally 2-years later.
The central nervous system's role in the experience of pain is emphasized by phantom limb sensations (Option B), where pain is perceived despite the absence of the limb, due to activity within the brain's neural circuitry. The propagation of signals along axon potentials and their processing in the brain highlights how pain perception can involve central mechanisms.
Explanation:The role of central nervous system activity for the experience of pain is best highlighted by phantom limb sensations. Phantom limb sensations are a phenomenon where individuals who have lost a limb still feel sensations, such as pain as if the limb were still present. This highlights the central nervous system's role in pain perception because the pain is derived not from the peripheral site of the amputated limb, but from the neural circuitry within the central nervous system itself.
Pain is a complex process that starts with nociception at sensory receptors and doesn't become the conscious perception of pain until it is communicated to the brain. Pain signals are transmitted by nociceptive pathways to different areas within the brain such as the thalamus and the somatosensory cortex for final processing. Perception of pain can be delayed due to the time taken for these signals to be propagated along the axon potential and reach the cerebral cortex. Various pathways indicate that pain can emerge even in the absence of actual physical stimuli, as seen in neuropathic pain or as a result of the central nervous system's activity, as is the case in phantom limb sensations.

b. deficiency causes diabetes insipidus
c. secreted in response to decreased blood glucose
d. helps regulate blood glucose
Answer:
d. helps regulate blood glucose
Explanation:
The insulin hormone is secreted by beta cells of the endocrine portion of the pancreas. Insulin is released in response to raised blood glucose levels. The function of this hormone is to make the body cells to take up the glucose from the blood. It specifically targets the liver and muscle cells and makes them absorb glucose from the blood. The absorbed glucose is stored in the form of glycogen in these cells and the blood glucose levels are restored to the normal range.

Suppose that in 2008, 859 comma 200 citizens died of a certain disease. Assuming the population of the country is 213 million, what was the mortality rate in units of deaths per 100,000 people?
Answer:
First, we have to divide the number of dead citizens by the number of the total population.
859,200/213 million
= 0.00403380281
Then, we multiply the result by 100,000 to obtain the mortality rate.
0.00403380281 x 100,000
= 403.380281.
This means that the mortality rate of citizens killed by this certain disease in 2008 is of 403,38.
Vascular tissue helps plants transport water against the force of gravity. Because of this, plants that lack vascular tissue do not grow very tall. True or false?
Answer:True
Explanation: plants which lack vascular tissue is known as non-vascular plants. Vascular tissues consist of Phloem and Xylem.
Xylem vessels transport water and mineral through the plants while phloem vessels transport nutrients and products of photosynthesis via the plant.
Non vascular plants lacks features like Bark, so they do not grow very tall, they remain low on the ground. Examples include; mosses, liverworts etcetera.
Final answer:
The statement is true; vascular tissues like xylem and phloem enable plants to transport water and nutrients effectively, supporting taller growth. Nonvascular plants lack this system, hence they generally remain small and close to the ground.
Explanation:
The statement that vascular tissue helps plants transport water against the force of gravity is true, and therefore, plants that lack vascular tissue do not grow very tall is also true. Vascular tissue, including xylem and phloem, is crucial for the distribution of water, minerals, and nutrients throughout the plant. This system is similar to the human circulatory system, though plants do not have a heart to pump fluids. Instead, plants rely on other mechanisms, such as transpiration and root pressure, to move water and nutrients.
Nonvascular plants, such as mosses and liverworts, lack these specialized tissues. Consequently, they must rely on direct water absorption and diffusion to move nutrients, which limits their size and height. Vascular tissue allows plants to transport resources efficiently over greater distances, supporting larger and taller growth. This evolutionary adaptation has enabled vascular plants to thrive in a wide range of environments, leading to the diversity we see today.
Plants like ferns, which evolved early in plant history, demonstrate the advantages of vascular tissues as they can grow relatively tall and survive in drier environments compared to their nonvascular counterparts. The presence of vascular tissues has been a key factor in the successful colonization of land by plants.
Mariam has just recently gotten pregnant. Before she even found out, her embryo had already formed three germ layers. What is the layer that will develop into the nervous system?
Answer:
Ectoderm
Explanation:
In addition to other structures, ectoderm gives rise to all the nervous tissues. Induction by notochord makes the ectodermal cells to form the neural plate. The elevated ends of the neural plate form the neural folds by the end of the third week of pregnancy. The fusion of neural folds gives rise to the neural tube. Brain and spinal cord develop from the neural tube. Some of the ectodermal cells transform into neural crest cells which in turn give rise to sensory neurons and the postganglionic neurons of the peripheral nerves.
Imagine a planet that has a similar atmospheric pressure to Earth (760 mmHg) but different concentrations of gases in its atmosphere. On this hypothetical planet, oxygen makes up 10% of the atmosphere, carbon dioxide makes up 15%, and nitrogen makes up the remaining 75%. Based on this information, what is the partial pressure of oxygen on this new planet?
Answer:
"76 mmHg" is the partial pressure of oxygen on this new planet.
Explanation:
Atmospheric pressure on air on earth = 760 mmHg
On an unknown planet :
Oxygen makes up 10% of the atmosphere.
The mole fraction of oxygen gas can be written as [tex]x_1 = \frac{10}{100} = 0.1[/tex]
Carbon dioxide makes up 15% of the atmosphere.
The mole fraction of carbon dioxide gas can be written as [tex]x_2 = \frac{15}{100} = 0.15[/tex]
Nitrogen makes up the remaining 75% of the atmosphere.
The mole fraction of nitrogen gas can be written as [tex]x_3 = \frac{75}{100} =0.75[/tex]
Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)
Partial pressure of gases can be calculated by the help of Dalton's law of partial pressure:
Partial pressure of oxygen gas :
[tex]p_1 = p \times x_1[/tex]
[tex]= 760mmHg \times 0.1\\=76mmHg[/tex]
Partial pressure of carbon dioxide gas :
[tex]p_2 = p \times x_2[/tex]
[tex]= 760mmHg \times 0.15\\= 114mmHg[/tex]
Partial pressure of nitrogen gas :
[tex]p_3 = p \times x_3[/tex]
[tex]= 760mmHg \times 0.75\\=570mmHg[/tex]
"76 mmHg" is the partial pressure of oxygen on this new planet.

In _______ balance, the two sides of a composition on either side of an imaginary vertical dividing line correspond to one another in size, shape, and placement of form.Selected Answer:a. symmetrica lCorrect Answer:a. symmetrical
Answer:
Symmetrical balance.
Explanation: Anatomically, equal distribution of body organs and parts within an organisms to give proportions of shapes, sizes, and forms of the divided sides or halves is called body symmetry
Asymmetrical balance has two sides with each side's size, shape and placement form different from one another, (not match) but yet well balanced.
Therefore the correct option is Symmetrical balance, just like mirror image in which the two side are exactly matched and balanced.
Therefore, if an imaginary line is vertically drawn through the center of composition of the object then the forms on each side of the axis produced should be proportionate to one another in size, shape and placement.They may be view as mirror image of one another but not with 100% perfect similarity.
In ideal cases to get a perfect symmetrically balanced composition, centering is the method usually used.However, most center design may produce flat shape which may be not give good symmetry.

Y = 0.335
Yellow = 0.3
______________________________________________________
[tex]Frequency of green allele = GG+ \frac{YG}{2}[/tex]
(because the other half of the YG (blue) genotype comes from the G allele)
Therefore frequency of G = 0.09 + (0.49/2)
G = 0.49 + 0.245
G = 0.335
Green= 0.7
Therefore, the answer is C
c) yellow = 0.3, green = 0.7
The calculation is as follows:
The frequency of Y = 0.09 + (50% of 0.49)
Y = 0.09 + 0.245
Y = 0.335
Yellow = 0.3

When an infant is upset, a caregiver's soothing actions influence the infant's neurobiological regulation of emotions and lower the level of stress hormones.
A. True
B. False
Answer:
True
Explanation:
Infants unlike children of higher age and adults carry emotional baggage and distress and are unable to come out of that without assistance of elders. Therefore, a care giver has to take care of fulfilling the emotional requirement of infants by adopting and using soothing strategies such as hugging, careful touch etc.
An infant has undeveloped and un-specialized anterior cingulate cortex which plays an essential role in acting as an interface between cognition and emotion. Therefore, soothing actions and strategies help an infant from dealing with his/her emotional distress.

The lemming is a small mammals with a very high daily energy expenditure for its size. Based on what you learned in the panda case study, what would you predict about the lemming?
A) It would have a very large brain, heart and kidney for its sizeB) It would be a very active animal.C) It would have a very high metabolic rate for its size.D) B and C only.
E) All of the above.
Answer: B and C only (Option D)
B. It would be a very active animal.
C. It would have a very high metabolic rate for its size.
Explanation:
Lemming is a mammal that has relatively small body size. Due to its small body size, it encounter issues when exchanging material from the extrinsic environment. Lemming’s surface: volume ratio affects its energy consumption. It consumes higher energy at much rates compare to their body size.
However, more energy consumption is directly proportional to increased metabolic activities within the body system for lemming. Hence, the activeness of lemming is determined by the rate of catabolic and anabolic reactions that takes place in the body system for their respective life activities functions (e.g thermal control).
