The divisions of the nervous system that have antagonistic actions, or opposing actions are A) motor and sensory. B) sympathetic and parasympathetic. C) presynaptic and postsynaptic.D) forebrain and hindbrain. E) central nervous system and peripheral nervous system.
Answer:
B) sympathetic and parasympathetic
Explanation:
e autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.

The large surface area in the gut directly facilitates _____.
Answer:
B. Absorption
Explanation:
Absorption is a process that takes place in the small intestines or ileum of the GI tract, in which simple and soluble nutrients are absorbed into the blood stream.Absorption is enhanced by several adaptations of the gut such as large surface area of the gut which directly facilitates absorption of nutrients.Presence of villi and microvilli in the gut increases the surface area for absorption of nutrients in the ileum.The large surface area in the gut, boosted by structures called villi and microvilli, facilitates the absorption of nutrients and water from ingested food. It also plays a role in the conversion of liquid chyme residue into semi-solid feces.
Explanation:The large surface area in the gut directly facilitates the absorption of nutrients. The surface of the gut is filled with structures called villi and microvilli, which increase the surface area and therefore the gut's ability to absorb nutrients. With their vast surface area, the gut can process huge amounts of food (up to 10 liters), liquids, and GI secretions a day, efficiently absorbing ingested food, electrolytes, and water.
The absorption doesn't only benefit nutrient acquisition but also allows for the absorption of water, converting liquid chyme residue into semi-solid feces in the process. In addition to this, the presence of around 100 trillion bacteria in the human gut also play a role in digestion and nutrient absorption.
And finally, the small intestine, with its villi and microvilli, is responsible for the absorption of most carbohydrates and proteins. Interestingly, bile salts and vitamin B12 are absorbed mostly in the terminal ileum region of the small intestine.

If blonde hair is dominant and designated as "b" and brunette hair is recessive and designated as "b," probability would predict that if a couple each with a "bb" hair color genotype had four children, _____ would have blonde hair.
Plummet squares help here: 4 children and dominant so 75% would probably have blonde hair. Sorry if it is wrong there are no answer choices so...
~ Destiny ^_^
If both parents were to pass on their brunette hair genes (with genotype 'bb') all their children will have brunette hair given that brunette is the recessive trait and can only be expressed when both genes are present.
Explanation:In genetics the dominant trait is the one that will appear even if an individual only has one copy of the dominant gene (in this case, blonde hair). The recessive trait (brunette hair in this case) will only appear if the individual has two copies of that gene. In the scenario presented both parents have the recessive brunette gene hence the genotype is 'bb' for both. Given this information if a couple each with a 'bb' hair color genotype had four children all these children would inherit the 'bb' genotype. Therefore assuming the traits for hair color follow simple Mendelian inheritance all children would be expected to have brunette hair. It's important to highlight that environmental factors and the possibility of mutations could potentially influence these outcomes to some extent but that's beyond the scope of this question.

There is a liquid capsule inside a cup full of liquid. The cup full of liquid has salt in it and the liquid capsule has no salt in it. In which direction will the solvent flow?
A. From the capsule to the larger cup
B. From the larger cup to the capsule
C. Equally between the capsule and the cup
D. The salt does not have to move
Answer:
A. From the capsule to the larger cup
Explanation:
Solvent movement occurs from region of higher concentration to that of its lower concentration. In the given example, the liquid capsule has higher solvent concentration since it does not have solute. Presence of solute in larger cup makes it hypertonic solution with respect to the liquid inside cup. Hence, solvent will move from hypotonic solution (liquid in capsule) to hypertonic solution.
The solvent, which is water, will move from the larger saltwater-filled cup to the capsule with no salt, due to osmotic pressure driving water towards the higher concentration of solutes inside the capsule.
Explanation:The direction in which the solvent will flow when there is a liquid capsule with no salt in it inside a cup full of salt-containing liquid is based on osmotic principles. The solvent, in this case water, will naturally move from an area of higher water concentration to an area of lower water concentration in an attempt to equalize the solute concentration on both sides of the membrane. Since the liquid inside the capsule has no salt, it has a higher water concentration compared to the saltwater in the cup. Therefore, the correct answer is:
B. From the larger cup to the capsule
This is due to the osmotic pressure that drives water towards the area with a higher concentration of solutes, which would be the inside of the salt-free capsule. The process of water moving across a semipermeable membrane from a less concentrated solution to a more concentrated solution is known as osmosis.
The membrane surrounding the ovary is the tunica albuginea. True or False
The answer to your question is true.
The membrane surrounding the ovary is the tunica albuginea. - False
Explanation:The membrane surrounding the ovary is not the tunica albuginea. It is called the ovarian capsule or ovarian cortex. The tunica albuginea is a dense connective tissue layer that surrounds certain other organs, such as the testes in males. In the case of the ovary, the ovarian cortex is beneath the tunica albuginea, and it contains the ovarian follicles where eggs are produced and stored.
So, while the tunica albuginea is an important structure, it is not the membrane that directly surrounds the ovary. The tunica albuginea actually refers to a dense connective tissue layer that surrounds certain organs, such as the testes and ovaries.

What are the roles of producers consumers and decomposers in an ecosystem
Answer: The producers refers to green plants that carry out the process of photosynthesis in order to produce food for themselves and others. The principal function of producers is to manufacture food for themselves and all other living organisms.
The consumers refers to those living organisms that can not produce their own food and have to depend on the food produce by others. Consumers can be categorized into primary, secondary and tertiary consumers depending on where they are located on the trophic levels. They can also be classified as herbivores, carnivores and omnivores depending on the type of food they eat. The major function of consumers is transference of energy. Consumers transfer the energy they obtain from the food they eat to those animals that feed on them.
The decomposers are those micro organisms that are majorly found in soils.The principal function of decomposers is to break down dead organic matters so that they can be absorbed by the roots of plants. The broken down organic substances serve as nutrients, which the plants used to grow and develop.
These three types of organisms work together in the ecosystem to maintain the balance of the ecosystem.
How does an autotroph differ from a heterotroph?

Sometimes critics charge that evolution is based on mere speculation because it cannot be directly observed or experimentally induced. Is this true of evolution by natural selection?
Answer:
False
Explanation:
When scientists speak of evolution as a theory they do not mean that it is a mere speculation. It is a theory in the same sense as the propositions that the earth is round rather than flat or that our bodies are made of atoms are theories. Most people would consider such fundamental theories to be sufficiently tested by empirical evidence to conclude that they are indeed facts. As a result of the massive amount of evidence for biological evolution accumulated over the last two centuries, we can safely conclude that evolution has occurred and continues to occur. All life forms, including humans, evolved from earlier species, and all still living species of organisms continue to evolve today. They are not unchanging end-products.
Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
The assertion that evolution by natural selection is based purely on speculation is not accurate. In science, the 'theory of evolution' is a thoroughly validated explanation of natural events that have been extensively tested and supported over time. Although large-scale evolutionary changes, like the formation of new species, occur over periods longer than a human lifespan and can't be directly observed, we have indeed witnessed instances of evolutionary processes.
Explanation:The criticism that evolution by natural selection is based on mere speculation and cannot be experimentally induced or directly observed is a misunderstanding of what a scientific theory represents. In scientific terms, a theory like the 'theory of evolution,' is a well-founded explanation of natural phenomena that has been tested and validated over time.
It's not 'just a theory' in the everyday vernacular sense of a guess or speculation. In fact, there is extensive support for this theory in multiple fields of science, including genetics, paleontology and biogeography. Further, the majority of working scientists back the theory of evolution.
When critics claim that evolution is not observable, it's essential to clarify that while we cannot directly observe large-scale changes like the formation of new species (since it happens over extended periods), we indeed can and have observed instances of evolutionary processes, such as antibiotic resistance in bacteria and changes in species in response to environmental pressures.

Kisspeptin is a protein in humans that has an important role in initiating secretion of the releasing factor gonadotropin-releasing hormone (GnRH). Endocrinologists are finding that the protein kisspeptin and its receptor are central to sexual maturation at puberty. Neurons that release kisspeptin carry estrogen receptors. If this is a negative feedback system, high levels of estrogen would be expected to: decrease kisspeptin synthesis. increase kisspeptin synthesis. neither increase nor decrease kisspeptin synthesis because steroid hormones do not affect protein synthesis.
Answer:
decrease kisspeptin synthesis
Explanation:
Kisspeptin is a protein involved in the regulation of gonadotropin-releasing hormone (GnRH): it stimulates the secretion of GnRH. GnRH than stimulate the release of gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. FSH stimulates the production of estrogens by the granulosa cells of the ovarian follicles.
In negative feedback system, high levels of estrogen will bind to their receptors on neurons that release kisspeptin and inhibit its further release.
High levels of estrogen would decrease kisspeptin synthesis in a negative feedback system by signaling the body to maintain hormone balance.
Explanation:If kisspeptin neurons have estrogen receptors and are part of a negative feedback system, then high levels of estrogen would be expected to decrease kisspeptin synthesis. This is because in a negative feedback system, when the levels of a hormone (in this case, estrogen) are high, it typically signals the body to reduce the production of the hormone or the initiators of its production to maintain homeostasis. Therefore, in this scenario, increased estrogen would lead to a decrease in kisspeptin production, which in turn would lead to a decrease in the release of gonadotropin-releasing hormone (GnRH), ultimately reducing the secretion of gonadotropins like Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
A 45-year-old man had coronary artery stents placed 2 days ago. Today, he is in severe distress and is reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mm hg, respiratory rate is 28 breaths/min, and oxygen saturation is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Which condition led to cardiac arrest?
Answer:
In the particular case, acute coronary syndrome (ACS) have occurred in the cardiac arrest. The ACS refers to a condition that arise due to the decrease of blood flow in the coronary arteries, such that the segment of the heart muscle is not able to function properly or dies. Some of the signs and symptoms of ACS are chest pain and discomfort, pain rising in your chest and in the arms, shoulders, neck, or jaw, indigestion, nausea or vomiting, shortness of breath, unusual fatigue, excessive sweating, restlessness, dizziness, or fainting.
Answer:
The given case is a result of acute coronary syndrome.
Explanation:
Acute coronary syndrome is a term given to the three kinds of coronary artery disorder, which are related to the sudden splitting of plaque within the coronary artery. The condition generally results from the accumulation of plaques or fatty deposits in and on the walls of the coronary arteries, that is the blood vessels that transmit nutrients and oxygen to the muscles of the heart. When the deposit of the plaque splits or ruptures, the formation of blood clot takes place. This clot prevents the flow of the blood to the muscles of the heart.

Ellis-van Creveld syndrome is a rare homozygous recessive disorder that affects bone growth. Individuals with this disorder are characterized by dwarfism, polydactyly, heart defects, and other symptoms. The recessive allele that causes it is extremely common in the Amish community of Lancaster County, Pennsylvania, and in the indigenous population of Western Australia. For example, the birth rate of this disorder in Lancaster County is 1 in every 5000 births ( compared to 1 in every 150,000 births worldwide). a) Approximately what percent of the Amish population are heterozygous carriers of the allele for Ellis-van Creveld syndrome? b) What percentage is homozygous dominant?
Answer:
1. 2.8%
2. 97.1%
Explanation:
If the birth rate of this disorder is 1 in every 5000 births it means that the frequency of the recessive homozygous genotype is 1/5000=0.0002If we name the gene for the disorder with A, than the genotypes are aa (homozugous recessive), Aa (heterozygous, carrier), AA (dominant homozygous).
According to the Hardy-Weinberg equation:
frequency of AA is p2 (P)
frequency of Aa is 2pq
frequency of aa is q2 (Q) and
p2+2pq+q2=1 (P+Q=1)
Q=0.0002 P=1-0.0002=0.9998
q= [tex]\sqrt[/tex]0.0002=0.014
p=[tex]\sqrt[/tex]0.9998=0.999
2pq=0.028=2.8%
2. According to the Hardy-Weinberg equation:
frequency of AA is p2 (P)
frequency of Aa is 2pq
frequency of aa is q2 (Q) and
p2+2pq+q2=1 (P+Q=1)
The frequency of the recessive homozygous genotype (Q) is 1/5000=0.0002
Q=0.0002
q2=0.0002 2pq=0.028 p2=?
p2= 1-0.0002-0.028 =0.9718=97.1%
Final answer:
Approximately 0.1% of the Amish population are heterozygous carriers of the allele for Ellis-van Creveld syndrome, and approximately 99.2% are homozygous dominant.
Explanation:The percentage of the Amish population that are heterozygous carriers of the allele for Ellis-van Creveld syndrome can be estimated using the Hardy-Weinberg equation. The formula for heterozygote frequency is 2 * p * q, where p represents the frequency of the dominant allele and q represents the frequency of the recessive allele. In this case, since the disorder is rare and the recessive allele is common in the Amish population, we can assume that [tex]q^2[/tex] quals the frequency of the disorder in the population. The frequency of the recessive allele, q, is then the square root of [tex]q^2[/tex]which is 1 in every 200 births. Thus, the frequency of the dominant allele, p, is 1 - q, which is 1 - (1/200) or 199/200. The heterozygote frequency is 2 * p * q, which is 2 * (199/200) * (1/200) or approximately 0.1%.
The percentage of the Amish population that is homozygous dominant can be estimated by squaring the frequency of the dominant allele, p. In this case, p is 199/200, so the homozygous dominant frequency is [tex](199/200)^2[/tex]ately 99.2%.

What statement does NOT pertain to the cephalic phase of gastric secretion? (It controls the rate at which chyme enters the small intestine., It is triggered by sensory input, such as sight, as well as mental input, such as thinking about food., Mucous cells, chief cells, parietal cells, and G cells receive signals through the submucosal plexus., It usually lasts only a few minutes.)?
Answer:
It controls the rate at which chyme enters the small intestine
Explanation:
Cephalic phase is one of the phase of gastric secretion (other two are gastric phase and intestinal phase) that begins even before food enters the oral cavity. Thinking of food stimulates the release of gastric juice via parasympathetic nervous system). Food that enters the stomach also stimulates the secretion of gastric juice by parietal cells. Partially digested food directly activates G cells (Enteroendocrine cells) to secrete gastrin which also stimulates the release of gastric juice.
The statement incorrectly associated with the cephalic phase of gastric secretion is that it controls the rate at which chyme enters the small intestine; this is actually part of the intestinal phase.
Explanation:The statement that does NOT pertain to the cephalic phase of gastric secretion is "It controls the rate at which chyme enters the small intestine." This particular function is a component of the intestinal phase of gastric secretion, which begins when chyme enters the small intestine, triggering a myriad of digestive secretions and coordinating the activities of the intestinal tract, pancreas, liver, and gallbladder. Conversely, the cephalic phase precedes food entering the stomach and is initiated by sensory and mental stimuli such as the sight or thought of food, which through the central nervous system, stimulates the secretion of gastric juices in preparation for digestion. The cephalic phase engages mucous cells, chief cells, parietal cells, and G cells through signals transmitted via the submucosal plexus and is typically of short duration.
A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides into cells of each group and allowed DNA replication to begin. When replication was halfway completed, she injected a drug into the cells to stop replication. She then examined the cells to determine the distribution of the newly-synthesized DNA. She found each cell of group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm. What can the researcher conclude about the cells? A. Group B cells are eukaryotic because they must have a single origin of replication. B. The cells in group A are eukaryotic because they replicate their DNA in the cytoplasm or nucleus. C. Group A cells are prokaryotic because they must have many origins of replication. D. The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.
Answer:
D. The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.
Explanation:
The cells of group A are prokaryotic because it is prokaryotes which do not have a double membranous structure called nucleus for storing their genetic material. The genetic material of prokaryotes is spread in the cytoplasm in the form of a circular DNA which is called as nucleoid. Since they do not have a separate organelle like nucleus for storage of their genetic material, they are bound to replicate their DNA in the cytoplasm. In contrast to prokaryotes, eukaryotes have nucleus for storage of their genetic material and in eukaryotes replication is an exclusively nuclear event.
