Answer:

Explanation below.

Explanation:

The movement will help the people to exercise more.

It should be understood that the presence of mosquitoes and the situation of the region as a wet region will not allow people to do much exercise, but their movement to the dry region will allow them to do more exercise than that of the wet region.

Of the 200 to 400 million sperm cells released in a typical ejaculation, approximately how many do you think will reach the ovum
Travka [436]
Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.

How many body systems are in eating a single bite of turkey? PLSS HELP its duo in abt 6 mins!!​
NISA [10]

Answer:

There are 4 systems involved in this activity. these systems are: the skeletal, muscular, circulatory and digestive systems.

Explanation:

To eat a single bite of turkey it is necessary that 4 systems come into play and work together for this activity to be possible.

First, it is necessary that the turkey is brought to your mouth through the movement of its members. In that sense, the resqueletico and muscular systems will act because it is through them that the movements of the members are created.

Then you will need to bite the turkey, chew it, moisten it with saliva, swallow it and digest it. This work will be done with the digestive system that will manage all of these activities.

Finally, your body will need to absorb the elements that make up the turkey pedal that you ate and that were rescued by digestion, these elements are nutrients, proteins and others. All will be absorbed through the work of the circulatory system, which through the blood will carry the elements throughout the body.

Independent assortment of chromosomes is a result of _____.
Ann [662]

Answer:

the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.

Explanation:

Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.

This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.

Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.

Parental Phenotypes: "Yellow-Smooth", "Yellow-Wrinkled", "Green-Smooth", "Green Wrinkled".

Parental Genotypes: SsGg  ×   SsGg

Parental Gametes:  SG, Sg, sG, sg

<span>Smooth/Green </span>= S-G- = 9

<span>Winkled/Green </span>= ssG- = 3

Smooth/Yellow = S-gg = 3

Wrinkled/Yellow = ssgg = 1

Ratio would be: 9: 3: 3: 1

Hope this helps!
