When, during the cell cycle, is a cell's dna replicated?
a) mitosis
b) interphase
c) cytokinesis
d) telophase

Option A.

During Mitosis in S phase DNA is replicated.

Explanation:

S phase(synthesis phase) Is the second phase in interphase. It is during this phase that DNA is replicated or synthesized through mitosis in interphase. This phase allow DNA to be doubled before it enter the cell, the doubled DNA is divided into daughter cells.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
