How does the cardiovascular system deliver nutrients and oxygen to all cells in the body via the flow of blood? Select all corre

ct answers.
(The arteries carry blood away from the heart; the veins carry it back to the heart.)

(In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)

(Veins contain a series of one-way valves that close to prevent the back flow of circulating blood.)

(Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)

(The left ventricle pumps low-oxygen blood into the pulmonary artery, which branches off into smaller and smaller arteries and capillaries.)

(Carbon dioxide is released from the blood into the air via capillaries surrounding the heart.)

Answer:

1: (The arteries carry blood away from the heart; the veins carry it back to the heart.)

2: (In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)

4: (Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)

Explanation:

The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. ... In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta).

The arteries carry blood away from the heart; the veins carry it back to the heart. ... The blood travels from the main artery to larger and smaller arteries and into the capillary network. There the blood drops off oxygen, nutrients and other important substances and picks up carbon dioxide and waste products.

The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

How does sucrose move from source to sieve?
dybincka [34]

The sucrose move in source to sieve by active transport.

<h3>What is active transport?</h3>

Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.

In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element  by osmosis, which increases the hydrostatic pressure.

<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.

Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction

Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.
