Answer: The frequency of brown beetles is 0.32.
Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:
1 - 0.8 = 0.2
In Hardy-Weinberg principle,

2pq represents the frequency of heterozygote individuals, so:
genotype A1A2 = 2*0.8*0.2 = 0.32.
Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
Answer:
The added carbon is supplied by acetyl CoA and the 2 eliminated carbons are released as CO2.
Explanation:
TCA cycle or citric acid cycle occurs in the mitocondrial matrix.
The ist step of TCA cycle deals with the formation of citrate molecule bt the addition of Acetyl CoA with oxaloacetate. The acetyl CoA is a 2 carbon compound formed from pyruvate by the catalytic activity of pyruvate dehydrogenase .
The 2 eliminated carbons are released as carbon di oxide or CO2.The CO2 molecule is eliminated during the formation of alpha ketoglutarate from isocitrate .The second CO2 molecule is eliminated when alpha ketoglutarate is converted to succinyl CoA.
We all know that plants need water, but water in excess is as bad as not having water.
→ Dry rural areas struggle to get water, and that is why most of the things they plant are native plants (resistant to dry climates).
→ Rural areas with heavy rainfalls struggle in finding ways of protecting they're crops against the damage the rain can cause and the excess water.

Exercise lowers modest amounts of blood glucose and boosts the body's sensitivity to insulin.
Blood glucose is the concentration of sugar dissolved in the blood of a person. It is the prime source of energy for the body. When the blood glucose is very high, the person is likely to be diabetic. Exercise is necessary to burn the excessive glucose molecules in order to gain energy for the exercise.
Insulin is a polypeptide which regulates the glucose levels in the body. It is secreted by the pancreatic cells called Islets of Langerhans. The structure is composed of two chains: A chain and B chain, joined together by the disulfide bonds.
