8. A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? Answer​

Answers

Answer:

the cell was submerged in a hypotonic solution

Explanation:

The cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.

The plant elodea contains cell membrane and cell wall.

The cell wall is an elastic structure that is permeable to all molecules.

The cell membrane is however, selectively permeable.

For the plant to survive and function well, the fluid its submerged into must be isotonic or be able to maintain an osmotic balance.

When placed in a hypertonic solution, a strong concentration, exosmosis occurs.

Water flows out of the cell into its surroundings.

As a result, the vacuole shrinks and eventually pulls the cytoplasm from the cell wall.

Therefore, the cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.

5. Is the thickest of the heart's chambers and is responsible for pumping oxygen-
ated blood lu tissues all over the body.​

Answers

Answer:

1. Aorta

2. Left atrium

3. Right ventricle

4. The pulmonary artery

5. Left ventricle.

Explanation:

The aorta is the main artery of the body that carries the oxygen-rich blood to all the body parts except the lungs from the left ventricle. It is divided into main coronary arteries or blood vessels.

The left atrium is one of the heart chambers, it is located in the upper part of the heart on the right side that receives the oxygenated blood from the lungs through the pulmonary vein.

The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the pulmonary valve to MPA to the lungs to get oxygenated.

The pulmonary artery or the main PA (MPA) carries the oxygen-depleted blood from the right ventricle into the lungs, where blood becomes oxygenated.

The Left ventricle is the thickest muscle chamber of the heart responsible for the pumping oxygen-rich blood to the circulatory system and to the body through the aorta.
