<span>e. </span>The percentage of mice that are homozygous recessive: __36%_______

Let us assign the dominant allele (that of brown hair) letter R while

We assign the recessive allele (that of white hair) letter r

We then note down the Hardy-Weinburg equation p2 + 2pq + q2 = 1

Brown fur population (p2 + 2pq) = 64% = 0.64

White fur population (q2) = 36% = 0.36

Then we also remember that the frequencies of both allele add up to 1 (p + q = 1);

Therefore q = ü.36 = 0.6

P = 1 – q = 1 – 0.6 = 0.4

The heterozygous population will be 2*0.6*0.4 = 0.48 = 48%

Homozygous domain population will therefore be (64% - 48%) = 16%

An organism that feeds upon primary consumers is known as a _______.

Alex777 [14]

***see attached pic***

In the energy pyramid for any given ecosystem, the most energy available is at the bottom and the least energy available is at the top.

At the bottom of the energy pyramid are the producers (plants and other photosynthetic organisms). The first group of organisms that consume the producers are called the primary consumers (herbivores). The next group of consumers are the secondary consumers, and then the tertiary consumers and quaternary consumers.

Correct Answer: B

Carbon is found in all living organisms. the constant flow of carbon on earth through organisms and the air is known as the carb

NARA [144]

According to the research, most of the carbon quickly enters back into the atmosphere in the form of carbon dioxide.

<h3>What is the carbon cycle?</h3>

It is the process that describes the flow of carbon (in the form, for example, of carbon dioxide) in the atmosphere, the ocean, the terrestrial biosphere.

Thus, the CO2 in the atmosphere passes through photosynthesis to the plants, also the cycles of respiration and microbial decomposition intervene, which release new CO2 in gaseous form into the atmosphere.

Therefore, we can conclude that according to the research, most of the carbon quickly enters back into the atmosphere in the form of carbon dioxide.

(WILL GIVE BRAINLIST) Rabbits are very popular domesticated animals, so popular that there are over 300 breeds of domesticated r

dem82 [27]

1) Breed A average weight = 9 pounds. Breed B average weight = 12.125 pounds. 2) Parentals' genotype, female size, number of deliveries, food, competition. 3) Genetic and non-genetic factors.

<h3>What is an average?</h3>

The average is the arithmetic media.

It can be calculated by adding the values of all the provided numbers, and then dividing the result by the total amount of numbers.

1) Average weights

Breed A: 10, 8, 7, 10, 9, 9, 10, 9

Average: (10 + 8 + 7 + 10 + 9 + 9 + 10 + 9) / 8 = 72 / 8 = 9 pounds.

Breed B: 10, 12, 14, 13, 10, 15, 11, 12

Average: (10 + 12 + 14 + 13 + 10 + 15 + 11 + 12) / 8 = 97 / 8 = 12.125 pounds.

2) Influencing factors:

Genetics: Individuals' size and weight can be inherited from their parents.

Female size: If the female is small, there are more probabilities of having small progeny than big ones, especially if the litter is numerous. This factor is known as uterine capacity.

The Number of deliveries: It is also significant the female's number of deliveries. Very young inexperienced mothers produce smaller litters and small-sized progeny than expert mothers.

Food: Individuals that are fed with a compete high-quality food will be bigger and will weigh more than those that are fed with poor-quality food.

Competition: If litters are numerous or there are many individuals, competition for resources might increase, leading the individuals to express lower weight.

<h3>How to track the growth rate?</h3>

To track the growth rate, we could consider genetic factors and non-genetic factors.

Genetic factors are related to the parentals' genotypes. The progeny inherit the alleles from their parents, and allele combinations determine the size and weight of individuals.

Non-genetic factors refer to the parental conditions before mating, and to external environmental factors.

To track the growth rate of the two rabbit breeds we could

Analyze the phenotypes and genotypes of the parents.

Evaluate the state of each parent before mating. At this point, we could consider age, size, sèxual maturity, experience, number of deliveries, receptiveness, if females are still breastfeeding or if they have recently wean, among other factors to analyze.

We could also consider the birth weight and the weaning weight, which are highly correlated, and give information about nourishing during gestation and lactation.

External factors such as food quality and quantity, stressful factors, diseases, seasons, temperature, and others are also important to consider.
