There are three main checkpoints in the cell cycle. Each checkpoint serves a different purpose and have their certain cyclins present. At the G1 checkpoint, a cell undergoes certain conditions to see if it is prepared for cell division. If a cell receives restrictions from the G1 checkpoint and can not continue into the next phase, what could the cell do next?
A) All cells pass the G1 checkpoint and enter into the next phase.
B) The cell can enter the G0 (resting stage) until conditions can improve.
C) The cell will always go directly into the G2 checkpoint to continue the cell cycle.
D) The cell will directly enter the M phase and all of the errors will be fixed during this phase.

B

Explanation:

it will go into G0 until conditions improve. If they dont it will go through apoptosis

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
