Assuming complete dominance and following the product probability rule, the probability of obtaining an offspring that is triply dominant AABBCC is 1/32.

We talk about complete dominance when the dominant allele completely masks the recessive allele. It is an inheritance pattern.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.

Many genes show complete dominance.

In the exposed example, we need to cross AaBbcc x AaBbCc and calculate the probability of getting offspring that is triply dominant. To do it, we will follow the product probability rule.

The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time.

It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.

This rule is based on the dependence or independence of the events. If two events A and B are independent of each other, the occurrence of one of them does not affect the occurrence of the other one.

For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is

P(A∩B) = P(A) x P(B)

Since these are independent genes, for easier calculations, we can perform crosses that involve each of the genes separately -events-, and then multiply de results according to the genotype we are interested in (AABBCC).

Gene A

Parentals) Aa   x   Aa

Gametes) A   a     A   a

Punnett square)   A      a

                     A    AA    Aa

                     a     Aa    aa

F1)  1/4 AA

     1/2 Aa

     1/4 aa

Gene B

Parentals) Bb   x   Bb

Gametes) B   b     B    b

Punnett square)   B      b

                    B       BB    Bb

                     b       Bb   bb

F1)  1/4 BB

     1/2 Bb

     1/4 bb

Gene C

Parentals) cc   x   Cc

Gametes) c    c     C    c

Punnett square)   C      c

                      c      Cc    cc

                      c      Cc    cc

F1)  1/2 Cc

      1/2 cc

The probability of getting and individual with genotype AABBCC is

P(AABBCC) = P(AA) x P(BB) x P(CC)

P(AABBCC) = 1/4  x 1/4  x 1/2

P(AABBCC) = 1/4  x 1/4  x 1/2

P(AABBCC) = 1/32

The probability of obtaining an offspring that is triply dominant AABBCC is 1/32.

Answer:

Polar regions

Explanation:

Because plants don't survive in the extreme cold and ice that cover these regions year-round.

Due to their intense and harsh environmental circumstances, polar regions like the Arctic and Antarctica often have the lowest levels of biodiversity. So, the correct option is B.

The term "biodiversity", which is short for "biological diversity", describes the range of living things and ecosystems that exist on Earth. It includes a wide range of species, genetic diversity within those species, a wide range of environments, and a range of ecological processes. Humans benefit greatly from biodiversity as it provides them with food, medicine and ecological services such as pollination and water and air purification.

Because of their intense and harsh environmental conditions, polar regions such as the Arctic and Antarctica often have the lowest levels of biodiversity. These regions have a relatively limited diversity of species because the cold and dry conditions make it difficult for many species to live. Furthermore, these areas often have low population density due to the severe environment and scarce resources.

So, the correct option is B.

The superior esophageal sphincter is a muscular ring that separates the pharynx from the esophagus, has voluntary activity and is responsible for initiating swallowing.

What is the superior esophageal sphincter?

It is located immediately after the pyriform sinuses, it is a muscular ring located in the high pressure area between the pharynx and the esophagus.

This prevents the passage of air into the digestive tract during inspiration and the reflux of gastric material into the pharynx, relaxing to open the esophagus.

In order for a muscle-building athlete to keep muscles in good shape, it is necessary to synthesize more muscle protein than is consumed, which is known as nitrogen balance..

Therefore, we can conclude that the superior esophageal sphincter is a muscular ring that separates the pharynx from the esophagus, has voluntary activity and is responsible for initiating swallowing.

water, compost , and chemical fertilizer

Water, compost , and chemical fertilizers is the best for maintaining the long-term health of farm soil.

Chemical fertilizers, such as urea, diammonium phosphate (DAP), and single superphosphate (SSP), are used to maintain the shortage of nitrogen, phosphorus, and potassium in the soil.

Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth.

Chemical fertilizers will nourish your plant, but the minerals will not linger in your soil. By creating rich, nutrient-dense soil with organic materials, your lawn will have a better chance of thriving on its own tapping into stored minerals when needed.

When dealing with unicellular organisms, many aspects will always remain the same between the distinct species. One such aspect is the reproduction method used universally by all unicellular species, that being reproduction through binary fission.

Explanation:

In evolution, which driving factor most consistently requires a small population as a precondition for its occurrence? Genetic drift Natural In evolution, which driving factor most consistently requires a small population as a precondition for its occurrence? Genetic drift Natural selection Nonrandom mating Mutation.

In evolution, Genetic drift is the driving factor which most consistently requires a small population as a precondition for its occurrence.

A change in the relative frequency of alleles within a population is an example of genetic drift. Natural selection, often known as the differential survival and reproduction of individuals across a population as a result of differences in phenotype, is one of the possible causes of this phenomenon.

Natural selection gives an advantage to some characteristics in a population, which results in certain individuals being able to reproduce while others, who have characteristics that give them a disadvantage, will provide their genes to subsequent generations. This will ensure that the allelic frequency of each successive generation will be distinct from that of the parent group.

Therefore, a subpopulation may become genetically diverse from its parent population due to genetic drift.

The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.

These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.

From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.

The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.

Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.
