olchik [2.2K]3 years ago
8 0

Answer: First option is correct.

Explanation:

NADH - It is used for mental alertness and clarity. It is also used in Alzheimer's disease.

It is used as a reducing agent to carry electrons

So, it is carrier of electrons.

NADH is known as electron donor because of which it is used in electron transport chain.

So, NADH - Electron carrier is correctly matched with its job description.

Hence , first option is correct.

one gene in a population of snails determines whether they are poisonous. being poisonous (P) is dominant over not being poisono
Harlamova29_29 [7]

Answer:

F (pp) = 0.04

F (Pp) = 0.32

F (PP) = 0.64

Explanation:

Studying population genetics, we used the Hardy-Weinberg equilibrium model. In the case of snails, the H-W principle predicts that the total number of cases in the population should follow the following equation: PP + 2.Pp + pp = 200.

If a population has 200 snails and 8 are affected by a recessive condition, we have 4% affected, or 0.04.

This means that 0.04 corresponds to p², and p corresponds to 0.2.

Therefore, P is equal to 0.8 because p + P = 1.

Knowing the allele frequencies, we go to the frequency of the genotypes.

F (pp) = p² = 0.04 = 8 snails

F (Pp) = 2.Pp = 0.32 = 64 snails

F (PP) = P² = 0.64 = 128 snails
