Human chorionic gonadotropin is secreted from the placenta. The correct option is D.
<h3>What is HCG?</h3>
HCG is known as Human Chorionic Gonadotropin.
It is a hormone secreted by the placenta during pregnancy.
The hormone specifically functions to thicken the wall of the uterus in order to be able to support the growing embryo.
It also signals to the body system to halt the process of menstruation.

Both phenotypes will be shown.
Answer:
Mitosis is a process of cell division that leads into formation of two daughter cells that are genetically identical to each other and to the original cell. So this is greatly important to living organisms because Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
Good Luck!!!
Explanation:
Sexual inter course is good for health. Its like exercise. It awakens the muscles and blood pumps faster. They also say the hormones released into your brain make you smarter. Intercourse can also be bad if your partner has disease. Hope this answer helps. And don't judge me
<span><u>The answer is A. 72.25 percent.</u>
The Hardy-Weinberg principle can be used:</span>
<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>
where <em>p</em> and <em>q</em> are the frequencies of
the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the
frequencies of the genotypes.
<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15
To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is
used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85
Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the
frequency of the RR genotype (p²):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.</span>
