Part A The Cell Theory states that:

Choose all that apply, and keep in mind that just because a statement is accurate does not necessarily make it a correct response to a question being asked. Choose all that apply, and keep in mind that just because a statement is accurate does not necessarily make it a correct response to a question being asked.

A. on early earth, the surface to volume ratio of the cell was much larger because the percent oxygen in the air was much less
B. all living things are composed of cells.
C. viruses are considered living things, but only in some cases
D. cells have more DNA in them in G2 than in G1
E. all cells arise from preexisting cells
F. the cell is the fundamental unit of life.
G. prions are living things

The following statements are true and are relevant to The Cell Theory:

B. all living things are composed of cells.

E. all cells arise from preexisting cells

F. the cell is the fundamental unit of life.

Explanation:

Although lower percentage of atmospheric oxygen in earlier times (220 million years ago) is true, it is not possible that the ratio was "much larger" than what it is today.

Option C is correct but not pertinent to the cell theory. Viruses are considered as living things once they are inside a host.

G1 and G2 are growth phases and have the same amount of DNA in them. It is during the mitotic phase that the DNA is increased. Hence, option D is incorrect.

Option G is false as well. Prions are not considered as living things, they are just proteins that can cause infections.

Hope that answers the question, have a great day!

that is true   : ) hope this you
