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
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.

Recognize what energy is and how it is transferred throughout living systems.
Explanation:
Energy is the ability to do work. There are two main forms of energy, potential and kinetic energy.
Potential energy is the energy at rest in a body
Kinetic energy is the energy due to motion
Energy is usually transferred throughout living systems when are transformed from one form to another. For example, chemical energy in food produced by plants is taken by animals as food. They then convert the chemical energy into other forms of energy like heat energy which they use for their daily activities.NUMBER 13 PLEASEEE!!!!!

Learning Task No. 2: Copy and complete each statement. Choose from the
words inside the box.
1. The main artery of the body, supplying oxygenated blood to the circulatory
system.
2. The upper right chamber of the heart that receives oxygenated blood from the
lungs.
3. The chamber within the heart that is responsible for pumping oxygen-depleted
blood to the lungs.
4. The artery carrying blood from the right ventricle of the heart to the lungs for
oxygenation.
5. Is the thickest of the heart's chambers and is responsible for pumping oxygen-
ated blood lu tissues all over the body.
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.

What molecule was the director of the entire protein building?
Answer:
(Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
Explanation:
Amino acids are small organic molecules that are the building blocks of proteins. They have an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable part called a side chain.
What are proteins?Proteins are big biomolecules and macromolecules that are composed of one or more long chains of amino acid residues. Proteins can be classified as either macromolecules or biomolecules.
Amino acids are the fundamental components of proteins. They are tiny chemical compounds that contain an alpha (central) carbon atom that is coupled to an amino group, a carboxyl group, a hydrogen atom, and a variable component that is referred to as a side chain.
They are responsible for the majority of the work that occurs within cells and are necessary for the structure, function, and control of the organs and tissues found throughout the body.
