Genetic recombination occurs during the Prolonged Prophase of Meiosis I.

Genetic recombination occurs during the Prolonged Prophase of Meiosis and it is the process in which deoxyribonucleic acid (DNA) are broken into pieces and this piece recombines to form a new combinations of alleles.

This recombination is what leads to creating genetic diversity.

Therefore, Genetic recombination occurs during the Prolonged Prophase of Meiosis I.

The genetic recombination occurs in meiosis during the stage of Prophase I.

Genetic recombination may be defined as the conditions when the molecules of the DNA exchange their genetic material with each other.

This process of genetic recombination also known as crossing over, which is responsible for the genetic diversity among individuals.

Genetic recombination occurs when homologous chromosomes are arranged in pairs and interchange the segments of the DNA.

Therefore, genetic recombination occurs in meiosis during the stage of Prophase I.

Answer:

Esophagus

Explanation:

In the digestion and absorption of food, the esophagus is the least involved.

It is a part of the digestive system, but all it does is simply pass the food down to the stomach.

The one that is least involved in the mechanical breakdown of food, digestion, or absorption is esophagus. The correct option is d.

Even though it is a vital component of the digestive system, the esophagus plays a much smaller role in the mechanical digestion of food than the other alternatives.

A muscular tube called the esophagus moves food from the mouth to the stomach by a process known as peristalsis, which calls for repetitive muscle contractions.

Its main job is to push food down the digestive tract so that it can travel more easily. Food is mostly mechanically broken down in the mouth while being chewed by the teeth and in the stomach while being churned by muscles.

The majority of digestion and nutrient absorption occurs in the small intestine.

Thus, the correct option is d.

The function of the extra compartments in the stomach of ruminant animals is to provide an area for their symbiotic bacteria to live.

In order to be able to digest cellulose which is the principal component of grasses, plant-eating mammals, otherwise known as ruminants, have extra stomach compartments.

These stomach compartments exist to make the digestion of cellulose easier through a symbiotic relationship with cellulose-digesting bacteria.

The compartments house these symbiotic bacteria and partially chewed plants are stored in them to facilitate digestion.

Explanation:

Because in the way I am thinking it's B, "School cooks should be educated on allergies to peanuts." It makes the most sense

Answer:  b

Explanation:

it can't be a since source 2 says "few people recognize..." which contradicts "students know what to do..."

it can't be c because there is no source comparing peanut allergies now vs. past.

it can't be d because you cannot infer this from the given data.

leaving us with b because since a majority of peanut allergies happen at school and not many know how to deal with an event with a peanut allergy, then teaching cooks about peanut allergies will help students in the case of an allergic reaction in school.

Answer:

We can find the value of p and q with the following 2 formula.

p + q =  1    and    p2 + 2pq + q2 =  1

Explanation:

Here,

q2=0.0036

So, q = [tex]\sqrt{0.0036}[/tex] = 0.06

Using formula, p + q =  1

p = 1 - q

p = 1 - 0.06

p = 0.94

So, based on the value of p and q you can find other required solutions.
