Answer 1

Answer: D

Explanation: It provides structure and protection to the cell.

Answer 2

1.- How does the cell wal contribute to the function of the plant cell?

D The cel wall provides strenght and rigidity. This is because it is a double phospholipid membrane.

2.- The lowest level of organization in an organism is:

D A cell, because cells are the independent units that make up the whole. This is part of the cell theory

3.- Which of the following best indentifies a way in which organs in an organims are similar to organelles?

7.- Which statement best describes the relationship.....

A. An individual´s inherited traits are determined by genes, which are located inside a person´s chromosomes.

8.- Which of the following is NOT one of the main components of the cell theory?

A.- All cells produce their own food for survival. This is not true, because only plant cells can do this
