Why does sexual reproduction result in more genetic diversity than asexual reproduction? A.Traits from two parents are combined.

B.More organisms reproduce this way.

C.Offspring grow in different environments.

D. Offspring come from identical parents.

Answers

Answer:

A. Traits from two parents are combined

Explanation:

Each time you have a sexual reproduction the offspring get a mixture of both the parents genes, making the offspring's genes unique. However since the asexual reproduction would produce an offspring with an identical genes to one parent, the genes are the same.

In other word the asexual reproduction does not have any diversity, and the sexual reproduction does because it is a mixture of two parents genes.

Answer: A

By diversifying offspring you enhance the ability to pass on desirable traits.

Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.What does this information best demonstrate?

Answers

Insulin is one of the significant hormones in the human body. The information about insulin and its mechanisms explains how the human body uses food for its energy requirements.

Generally, glucose obtained from the food that travels in the bloodstream is responsible for elevating the blood sugar level. The pancreas is an organ that helps in releasing insulin for controlling the blood glucose level. Insulin tends to get released in a feedback mechanism depending on the blood sugar level.

The mechanism of insulin best demonstrates the following:

Insulin along with glucagon helps in maintaining the state called homeostasis for the steady condition in the human body
Insulin is considered vital for cells to utilize glucose and obtain energy

Thus, the mechanism of insulin in the human body explains how energy is utilized by different cells and how insulin is important in maintaining homeostasis.

Radial symmetry
Bilateral symmetry
Asymmetry

Answers

The correct option is, B, that is, RADIAL SYMMETRY.
Symmetry refers to the balanced distribution of the duplicated body parts or shapes within the body of a living organism. There are different types of symmetry, we have bilateral, radial and asymmetrical symmetry.
Radial symmetry refers to the type of body plan in which the body parts are arranged around a central axis, that is, the body parts are arranged in a circle around an axis.

Answer:B

Explanation:

The Answer is radial symmetry
