Which type of traits are responsible for evolution?

Hitman42 [59]

Answer:

In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.

Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

When a person is exercising, the body needs to deliver increased amounts of oxygen to the muscles. Which component of blood ensu

Schach [20]

The red blood corpuscles have a pigment called hemoglobin that binds to the oxygen and carries it to the whole body in both the conditions, when the body is at rest or when the body is exercising. The oxygenated blood from the heart is carried to the various parts of the body and the de-oxygenated blood from various parts of the body is carried to the lungs where the exchange of gases takes place.

Which of the following does NOT characterize proteins?

8090 [49]

Answer:

The answer is C) They appear to be the molecular carriers of coded hereditary information.

Explanation:

Why NOT C) They appear to be the molecular carriers of coded hereditary information?

This is the job of the nucleic acids. It is composed of nucleotides which are the basic units of DNA and RNA. They carry genetic information about a certain organism.

<h3 /><h3>True of proteins:</h3>

A) They may be denatured or coagulated by heat or acidity.

Denaturation is the destruction of the protein's secondary and/or tertiary structures. The primary structure is not disrupted due to the tough peptide bonds and can only be broken down by acid. For heat denaturation, hydrogen bonds are destroyed, as in cooking of egg whites and medical equipment sterilization.

B) They have both functional and structural roles in the body.

There are many kinds of proteins that have functional and structural roles like hormones (FSH, LH), antibodies (IgA, IgM), enzymes (lipase, amylase), for storage/transport (hemoglobin, ferritin), and locomotion (actin, troponin).

D) Their function depends on their three-dimensional shape.

Just like hemoglobin, it's quaternary structure can carry 4 molecules of iron in one go. Enzymes are shaped accordingly to fit a specific substrate (lock-and-key model)
