It is referred to as a biochemical pathway because it converts the energy from the sun to chemical reactions that the plants can use in its cells
Answer:
Autosomes
Explanation:
The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female. Females have two X chromosomes, while males have one X and one Y chromosome.
Hope this helps!
<span>The answer is A. p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span>

Let's first distinguish alleles frequencies from
genotypes frequencies:
p - a frequency of R allele,
q - a frequency of r allele,
p² - a frequency of RR genotype,
2pq - a frequency of Rr genotype,
q² - a frequency of rr genotype.</span>
<span>
<span>The gene frequency of allele r changes from 0.38
to 0.40, thus:
q = 0.40</span>
Now, we will implement this in the following
equation:
p + q = 1
If q = 0.40, then:
p + 0.40 = 1
</span>⇒ p = 1 - 0.40<span>
</span>⇒ p = 0.60
<span>
<span>Now, the frequencies of both alleles are know
and it is easy to calculate the genotype frequencies:
- the frequency of RR genotype: p² = 0.60² = 0.36</span>
- the frequency of Rr genotype: 2pq =
2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² =
0.16</span>
<span>
<span>Therefore, the new genotype frequencies in
that population are p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span></span>
