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).

The amount of magnification you see through a microscope is extremely easy to calculate. You just multiply the power of each lens the image travels through together. So you have the equation
630 = 10 * x
where 630 is the total magnification and 10 is the magnification of the ocular lens. Now just solve for x by dividing both sides by 10
63 = x
So the objective lens has to have a power of 63x for your total magnification to be 630x</span>
Answer:
The correct answer is: we would lack the energy we need to function.
Explanation:
Glucose is a type of sugar that gives us energy. When we eat something that contains glucose, our body releases insulin, a hormone from our pancreas, which absorbs the excess glucose in the blood and stabilizes sugar levels. When insulin is released, it travels through the bloodstream to the body's cell. After that, the cells convert glucose into energy to use right then or store it for later use.
In other words, if our bodies could not metabolize glucose we would be hungry and exhausted because we would not get enough of the other nutrients (like proteins and fibers) to sustain our energy.
