Answer:

Sun(solar energy)

Explanation:

The sun is the ultimate source of energy in our solar system.

The chemical energy in plants all started out with solar energy from the sun.

During the process of photosynthesis;

green plants manufactures their food using sunlight.
in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.

Photosynthetic reaction simply converts solar energy from the sun into chemical energy.

Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.

Which statement describes the relationship between a gene and an allele?

omeli [17]

Answer: option B) A gene can take different forms called alleles.

Explanation:

An allele is one of the two or more different forms of the same gene.

For example, a trait such as seed shape is represented expressed a gene, but with allele of "RR" (round seeds) and "rr"(wrinkled seeds) observed physically by the farmers.

Thus, the correct answer is that a gene can take different forms called alleles.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability

Zinaida [17]

Answer:

Explanation:

Let the ability to break down the red color in beets be represented by the allele B. The inability would be represented by the allele b.

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

Bb x Bb

BB 2Bb bb

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

probability of their first child will be a secretor girl = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor = 1/2 x 3/4 = 3/8

2. Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.

= 3/4 x 3/4 = 9/16
