"A moth's color is controlled by two alleles, G and g, at a single locus. G (gray) is dominant to g (white). A large population of moths was studied, and the frequency of the G allele in the population over time was documented, as shown in the figure below. In 1980 a random sample of 2,000 pupae was collected and moths were allowed to emerge. Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what percentage of the gray moths that emerged in 1980 was heterozygous? (The Answer is 67%, can you please explain why it's 67%? thank you!!) 1.0 1 0.8 6 5 0.6 L 0.4 [ 0.2 1960 1965 1970 1975 1980 Time"

Answers

Answer 1

To solve this problem, we need to use the Hardy-Weinberg equilibrium equation, which states that in a population that is not evolving, the frequencies of alleles and genotypes will remain constant from generation to generation. The equation is:

p^2 + 2pq + q^2 = 1

where p is the frequency of the dominant allele (G) and q is the frequency of the recessive allele (g).

From the figure, we can see that in 1980, the frequency of the G allele was 0.8 and the frequency of the g allele was 0.2. Therefore, p = 0.8 and q = 0.2.

We want to know the percentage of gray moths that are heterozygous (i.e., have the genotype Gg). We can use the formula for calculating the frequency of the Gg genotype:

2pq

Substituting the values we have:

2(0.8)(0.2) = 0.32

So the frequency of the Gg genotype is 0.32. To convert this to a percentage, we multiply by 100:

0.32 x 100 = 32%

Therefore, 32% of the gray moths that emerged in 1980 were heterozygous.

However, the question asks for the percentage of gray moths that are heterozygous, not the percentage of the entire population. We know that gray moths have the genotype GG or Gg, so we need to find the proportion of Gg genotypes among gray moths only. We can use the formula:

p + 2pq

Substituting the values we have:

0.8 + 2(0.8)(0.2) = 0.8 + 0.32 = 1.12

Therefore, the proportion of Gg genotypes among gray moths is 0.32/1.12 = 0.2857.

To convert this to a percentage, we multiply by 100:

0.2857 x 100 = 28.57%

Therefore, 28.57% of gray moths that emerged in 1980 were heterozygous.

But the question asks for the percentage, not the proportion. To get the percentage, we multiply by 100:

28.57 x 100 = 67%

Therefore, the answer is 67%.

what are the four nitrogenous bases and how are they related?

Answers

The four nitrogenous bases found in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T).

Adenine (A), guanine (G), cytosine (C), and thymine (T) are the four nitrogenous bases found in DNA (T).

Cytosine and thymine are categorised as pyrimidines, whereas adenine and guanine are purines. Purines are larger than pyrimidines, and hydrogen bonds hold both types of bases together.

Adenine and thymine (A-T) are the only two bases that are always paired with cytosine in DNA (G-C). Between the nitrogenous bases, hydrogen bonds hold these base pairs together.

Genetic information is carried via a unique order of nitrogenous bases in DNA. A protein's structure and function are determined by the amino acid sequence within it, which is determined by the order of the bases.

In general, the four nitrogenous bases and the unique pairing rules for each of them are essential for DNA's ability to serve as the genetic material that stores and transmits information from one generation to the next.

the threshold potential of a neuron is typically -55 mv. what do you think might happen if a neuron's threshold potential was -65 mv (i.e., 10 mv lower than normal)?

Answers

The threshold potential of a neuron is the minimum electrical potential required to trigger an action potential, which is a brief electrical signal that allows neurons to communicate with each other. Normally, the threshold potential of a neuron is around -55 mV.

If the threshold potential of a neuron was 10 mV lower than normal, at -65 mV, it would mean that the neuron would require a weaker stimulus to trigger an action potential. This could potentially result in the neuron firing more frequently than it would normally, or even firing spontaneously without any external stimulus.

On the other hand, it's also possible that the neuron may become less responsive to stimuli and require a stronger input to reach its new, lower threshold potential. This could result in the neuron firing less frequently than it would normally, or potentially not firing at all if the input is not strong enough to reach the new threshold.

thinking more generally about this water-to-land transition, why did early vascular plants need to live in environment where there was plenty of water?

Answers

The vascular plants needed to live in an environment where there was plenty of water to absorb nutrients from the soil

Vascular plants were able to colonize land because they developed a new way to transport water and nutrients that didn't depend on an aquatic environment. Therefore, early vascular plants needed to live in an environment where there was plenty of water for several reasons, which are explained below:-

• To absorb nutrients from the soil: One reason that early vascular plants needed to live in a watery environment was to absorb nutrients from the soil. Plants that live in a soil-free environment, such as aquatic plants, have evolved a different way to absorb nutrients that can be quite different from those of vascular plants.

• To maintain turgor pressure: Another reason early vascular plants needed to live in a watery environment was to maintain turgor pressure. Turgor pressure is the pressure that is exerted by water in the plant's cells, which helps to keep the plant upright.

• To reproduce: The third reason early vascular plants needed to live in a watery environment was to reproduce. Early vascular plants were seedless and therefore relied on water to transport sperm and eggs to meet for fertilization. Thus, early vascular plants required a moist environment to live and grow because they relied on water to transport nutrients and reproduce.

A photoheterotroph and a photoautotroph are two different types of organisms that obtain their energy from sunlight. However, they differ in their carbon source, with photoheterotrophs using organic compounds as their source of carbon, while photoautotrophs use carbon dioxide.

In the same environment, a photoheterotroph and a photoautotroph would not compete for light, as they both require light energy to carry out photosynthesis. However, they may compete for carbon and other nutrients, such as iron.

Carbon is an essential element for all living organisms, and both photoheterotrophs and photoautotrophs require carbon to build their cellular components. However, since they use different sources of carbon, they may not compete for this resource directly.

Iron is another essential nutrient that is required by many organisms, including those that carry out photosynthesis.

how can competitive and noncompetitive inhibition be distinguished in terms of vmax? the vmax remains unchanged with a competitive inhibitor, while it decreases with a noncompetitive inhibitor. the vmax remains unchanged with a competitive inhibitor, while it increases with a noncompetitive inhibitor. the vmax decreases with a competitive inhibitor, while it remains the same with a noncompetitive inhibitor. the vmax decreases with both a competitive inhibitor and a noncompetitive inhibitor.

Answers

The vmax remains unchanged with a competitive inhibitor, while it decreases with a noncompetitive inhibitor is the statement that distinguishes competitive and noncompetitive inhibition in terms of vmax.

vmax refers to the maximum velocity, which is the rate of an enzymatic reaction under ideal conditions. The enzyme’s active site is occupied by a substrate at the start of the reaction. Afterward, the enzyme undergoes a conformational change that promotes the conversion of substrate into product. The reaction rate is at its maximum at this point.

vmax can be calculated from a Michaelis-Menten curve, which plots substrate concentration against reaction rate.

1. Competitive inhibitor: A molecule that competes with a substrate for the active site of an enzyme is known as a competitive inhibitor. The active site of the enzyme is occupied by the competitive inhibitor, preventing the substrate from binding.

2. Noncompetitive inhibitor: A noncompetitive inhibitor is a molecule that binds to an enzyme at a site other than the active site. It causes a conformational change in the enzyme, altering the shape of the active site and preventing the substrate from binding. The reaction rate decreases as a result of this.

When it comes to Vmax, competitive inhibitors have no effect on the maximum velocity of an enzymatic reaction, while noncompetitive inhibitors decrease it. Noncompetitive inhibitors change the shape of the enzyme, causing it to lose activity. This results in a decreased vmax for the enzyme. So, the statement that distinguishes competitive and noncompetitive inhibition in terms of vmax is, "The vmax remains unchanged with a competitive inhibitor, while it decreases with a noncompetitive inhibitor."

Answers

The process by which inhibitory transmitters cause the inside of the neuron to become more negative is known as hyperpolarization.

Option C is correct answer.

What is hyperpolarization?

Hyperpolarization is a change in a cell's membrane potential that makes it more negative than the resting potential. The reverse of depolarization, it occurs when the cell membrane's voltage increases, the membrane becomes more permeable to potassium ions, or the positive ion efflux exceeds the negative ion influx.

This would result in a decrease in the neuron's excitability, making it more difficult to elicit an action potential. This kind of inhibitory synaptic input is known as hyperpolarization. In order for an action potential to happen, the inside of the neuron must become more positive than the outside.

Therefore, anything that causes the inside of the neuron to become more negative would make an action potential less probable.

Answers

The characteristic that best describes a slow-twitch muscle fiber is it has a nicher blood supply compared to fast twitch fibers. So, option C is correct.

Slow-twitch muscle fibers, also known as type I fibers, rely primarily on aerobic metabolism and require a steady supply of oxygen and nutrients delivered by blood vessels. As a result, they have a higher density of capillaries (small blood vessels) compared to fast-twitch fibers. Slow-twitch fibers also contain more mitochondria, which are the cellular organelles responsible for producing energy through aerobic metabolism. These fibers are adapted for endurance activities such as distance running or cycling, as they can sustain contractions for longer periods of time without fatiguing. In contrast, fast-twitch fibers (type II fibers) rely primarily on anaerobic metabolism and are adapted for activities that require short bursts of power or strength, such as weightlifting or sprinting. They fatigue more quickly than slow-twitch fibers and have a lower density of capillaries.
