Humans have 46 chromosomes in each somatic cell. a. How many chromosomes does a child receive from its father? b. How many autos
GarryVolchara [31]

Answer:

Explanation:

<u>a. How many chromosomes does a child receive from its father?</u>

Every person receives half of their chromosomes from their father and half from their mother. For that reason, if humans have 46 chromosomes in each somatic cell, 23 of them come from the father.

<u> b. How many autosomes and how many sex chromosomes are present in each somatic cell? </u>

Each somatic cell has 46 chromosomes in total; of which 22 pairs are autosomes and 1 pair are sex chromosomes. Therefore, 44 chromosomes are autosomes and 2 chromosomes are sex chromosomes (the X and/or Y chromosomes).

<u>c. How many chromosomes are present in a human ovum? </u>

The human gametes (ovum in women and sperm cell in men) have half of a somatic cell's genetic material, so that when they combine in a zygote to create their child, they form an initial cell with 46 chromosomes in total. The ovum therefore has 23 chromosomes: 22 autosomes and 1 sex chromosome.

<u>d. How many sex chromosomes are present in a human ovum?</u>

As I mentioned in the previous question, a human ovum has 1 sex chromosome. That way, when it combines with a sperm cell, which also has 1 sex chromosome, they form a zygote with <u>a pair</u> of sex chromosomes (one that comes from the mother and one from the father).

How does having a diverse gene pool help a species survive
timurjin [86]
So that there is more gene variation. Let's say if they all had the same genes, one specific disease would be fatal for the species' existence since they would all be the same. The diverse gene pool allows species to develop different characteristics that can help them defend against disease

Secondly, explain why energy is not just provided by the simple hydrolysis of ATP.
Nataliya [291]

Answer:

The exergonic reaction of hydrolysis of ATP must be coupled to an endergonic reaction to perform work or to power other reactions.

Explanation:

ATP (adenosin triphosphate) is hydrolized to give ADP and releases energy as follows:

ATP + H₂O ⇆ ADP + Pi + energy

The released energy itself is not used to power biochemical reaction. In order to power other reactions, ATP hydrolysis- a energetically favorable reaction- is coupled to another energetically disfavorable reaction. The linking or coupling is performed through a shared intermediate, which is often a phosphorilated molecule. For example, in the formation reaction of sucrose from glucose and fructose, an intermediate is formated by the transfer of a phosphate group (Pi) provided by ATP hydrolysis. Then, the phosphorilated intermediate (glucose-Pi)- wich is unstable- reacts with fructose in a spontaneous reaction to give sucrose.
