It was found that the C4 protein promotes synaptic pruning during brain development in the teenage years. This is a normal process in brain development that is important for removing unnecessary connections between neurons and establishing a mature brain structure. However, high expression levels of a certain allele of C4 can lead to too much pruning, which may promote the onset of schizophrenia. The variation observed at the C4 gene which leads to the greatest increase in risk was found to cause a 25% increase in the risk of developing schizophrenia. The baseline risk in the population is 1%. What is the risk of an individual with this variant developing the condition?a. 0.25%.
b. 1.25%.
c. 25%.
d. 26%.

Answers

Answer:

b. 1.25%

Explanation:

Variations observed in C gene has increase in risk of 25% to develop schizophrenia. It is a kind of an abnormality in which a person interprets reality unrepresentative. The baseline risk in population is 1% then there is 1.25% risk associated with an individual to develop this condition.

Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.

Answers

Answer:

This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions  

Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.  

Explanation:

An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.

Besides oxygen exchange, the respiratory system also functions to eliminate (Click to select) . Too much of this gas can cause a(n) (Click to select) in blood pH, compromising homeostasis.

Answers

Answer: Carbon dioxide, decrease

Explanation:

Cellular respiration is a set of reactions by which organic compounds (sugars) are degraded by oxidation to inorganic substances. This process provides energy in the form of ATP and to achieve this, many reactions occur in which electrons are passed from one molecule to another, called redox reactions. In the case of aerobic respiration, the final electron acceptor is molecular oxygen, which is reduced to water.  Oxygen, like any gas, crosses the plasma membrane and then the mitochondrial membrane, and in the mitochondrial matrix it binds electrons and protons, forming water. It is in this final oxidation and in previous processes that energy is obtained. The reactions that extract energy from sugars such as glucose are catabolic reactions since a large molecule is broken into smaller molecules. For example, when glucose is broken down in the presence of oxygen, six molecules of carbon dioxide (CO2) and six molecules of water are obtained. Both CO2 and water are eliminated by lung exhalation.

In the event that this carbon dioxide is not completely eliminated, something called respiratory acidosis occurs, which is one of the disorders of the acid-base balance due to a decrease in the frequency of respirations or hypoventilation. The increase in the concentration of carbon dioxide in the blood causes the pH value to decrease. This scale is a measure of the degree of acidity or alkalinity of a substance or solution. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more alkaline. Carbon dioxide is constantly produced as the body metabolizes energy, which will accumulate in the circulation rapidly if the lungs do not remove it properly. Alveolar hypoventilation thus leads to an increase in arterial CO2 partial pressure. The increase in pressure in turn decreases the ratio of bicarbonate (HCO3) to bicarbonate pressure with a consequent increase in acidity or decrease in blood pH. The body's metabolism rapidly generates a large amount of carbonic acid (H2CO3) and non-volatile acid. The lungs normally excrete the volatile fraction through ventilation without accumulation of acid in the blood but in this case this is not possible and this accumulation of carbonic acid causes the pH to rise. This disrupts homeostasis, a form of equilibrium that is achieved through a network of feedback control systems that constitute the self-regulatory mechanisms.

Answers

Answer:

6.25%

Explanation:

Find the number of different gametes that can be produced

number of gametes produced = 2^n

n is the number of allele pairs that are heterozygous

there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff

2^4 = 16

abCdeF is one of the 16 genotypes that could be produced

to find the percentage, divide 1 and 16 and multiply by 100

1 ÷ 16 = 0.0625

0.0625 × 100 = 6.25

Explain the role of cellular respiration in a cell.

Answers

Answer:

Every cell performs a type of cellular respiration as it is required to produce energy. The point of cellular respiration is to turn high-energy molecules, know as glucose, into ATP, a form of usable energy. There are two types of respiration, aerobic and anaerobic. Aerobic goes through 3 stages and produces the most ATP by using oxygen and releasing carbon dioxide. Anaerobic does the same job but only uses one stage and produces much less ATP. This process gives the cell energy and continues the carbon cycle.
