Base is the chemical that a DNA segment codes for. A is the best choice.

The biological substances known as nucleobases, commonly referred to as nitrogenous bases or simply bases, contain nitrogen and combine to produce nucleosides, which are subsequently parts of nucleotides, which are the fundamental constituents of nucleic acids.

The entire query is attached.

The base is the chemical that a DNA segment codes for.

Therefore, choice A is the best one.

The substance that is coded for by a length of DNA is base. The correct option is A.

Nucleobases, also known as nitrogenous bases or simply bases, are nitrogen-containing biological compounds that form nucleosides, which are then components of nucleotides, all of which are the basic building blocks of nucleic acids.

The complete question is attached.

The substance that is coded for by a length of DNA is base.

Thus, the correct option is A.

Which statements describe the movement of blood through the heart? Check all that apply.

vlada-n [284]

Answer:

The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.

In humans, four chambered heart is present with two atria and two ventricles.

Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).

Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.

Both the atria contract at the same time to drain their blood into respective ventricles.

The ventricles undergo relaxation while receiving blood.

The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".

The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.

The left ventricle passes the oxygenated blood through aorta to all the parts of the body.

The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
