Which of the following plant-cell organelle supports and maintains the cell's shape and protects the cell from damage? A. cell membrane B. cell wall C. chloroplast. D. vacuole

Answers

Answer 1

Answer:

Answer;

-Cell wall

Explanation;

-The cell wall is thick and fibrous and provides a barrier between the cell and its external environment.

-The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.

-A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include: Support: The cell wall provides mechanical strength and support.

Answer 2

Answer:

Cell wall supports and maintains the cell's shape and protects the cell from damage (option B)'

What is Cell wall?

The plant cell is protected by a layer called the cell wall, which encloses the cell membrane. This rigid structure, composed of cellulose offers both support and safeguarding functions, for the cell. Additionally the cell wall plays a role, in preserving the cells shape and preventing it from rupturing when exposed to pressure.

The cell membrane on the hand forms an outer layer encompassing every type of cell.

Valence is the number of electrons an atom must gain or lose in order to _____ its outer energy level or have a stable octet in its outer shell.complete
lose
gain

Answers

The correct answer is complete.

Valence is the number of electrons an atom must gain or lose in order to complete its outer energy level or have a stable octet in its outer shell. In the first energy level it can have only 2, but later levels can have 8, that is, an octet.

Answer;

Complete

Valence is the number of electrons an atom must gain or lose in order to complete its outer energy level or have a stable octet in its outer shell.

Explanation;

-Valency is the number of electrons that an atom requires to gain or lose to form a complete configuration or an octet configuration.

-Atoms tend to lose or get electrons in order to achieve the electronic arrangement of atoms of the noble gases. An ion is an atom or group of atoms having an overall electrical charge. Atoms gain electrons to form cations (positively charged atom), while other lose to form anions (negatively charged atoms).

How often does the body perform cellular respiration?A.once in the morning and once at night
B.only at night
C.continuously
D.only when the body runs out of ATP

Answers

Ans. (C).continuously.

Cellular respiration can be defined as a metabolic process, which involves breakdown of carbohydrate molecules to produce energy in the form of ATP molecules. These ATP molecules release energy during chemical hydrolysis.

Cells present in body require a continuous supply of energy to preform all of metabolic reactions. Hence, cells perform cellular respiration continuously or constantly.

Thus, the correct answer is option (C).

c. constantly.

hope this helps!
