Answer:
Homeostasis
Explanation:
Homeostasis: It is referred to as the ability of a species to maintain a state of internal balance and changes in outside factors. When calcium levels decrease in the human body, the gland known as parathyroid releases hormones. If calcium levels increase, the thyroid gland helps out the calcium by lowering blood calcium levels and fixing calcium in the bones.
Glucose is known as the basic form of sugar. When glucose levels increase in the human body, the gland which is called Pancreas helps to releases a hormone known as insulin. If blood glucose levels decrease, the liver helps to converts glycogen which is present in the blood to glucose.
Answer:
Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.

If u still need help send the choices in the comments and I’ll answer:)
The answer is <span>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>The gene frequency of allele r changes from 0.38 to 0.40, thus:
</span>q = 0.40
Now, we will implement this in the following equation:
p + q = 1
If q = 0.40, then:
p + 0.40 = 1
⇒ p = 1 - 0.40
⇒ p = 0.60
Now, the frequencies of both alleles are know and it is easy to calculate the <span>genotype frequencies:
-</span> the frequency of RR genotype: p² = 0.60² = 0.36
- the frequency of Rr genotype: 2pq = 2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² = 0.16
Therefore, the new genotype frequencies in that population are <span>p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span>
