Biology

Answer:

Option B, increased exposure to UV light increases the risk of a mutation occurring

Explanation:

Ultraviolet radiations (UV) coming from the sun are radioactive waves that affect the skin. They not only cause skin infection, irritation, but are are also potential source of cancer causing agent . Some times these radiations on prolonged exposure  causes genetic mutations in the skin cells which continues though ages.

Ultraviolet rays are short wavelength radiations and the shorter is the wavelength of any radiation, the greater is the potential harm caused by it.

Hence, UV rays are harmful.

Option B 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

Why is Mitochondria different in the cells of older people ?
Vlad1618 [11]
Well, mitochondria are the energy supplying organelles.

Knowing this, the mitochondria is different in the cells of older people because its been damaged, its called Mitochondrial Aging. When mitochondria age, just like us, they get damaged. And when they get damaged they damage our age, in a sense that we get older. This is how it is different in older people.
