Answer:
The correct answer is - at the G1/S phase and G2/M phase.
Explanation:
The G1/S transition phase or checkpoint is a phase where the cell cycle arrested if during the evaluation of the DNA found damaged or other factors including external factors. Due to this evaluation and inadequate conditions, the cell will not enter the S phase.
The G2/M phase or transition phase is a checkpoint which takes place just before the M phase that ensures that all replicated DNA is not damaged before entering mitosis phase or M phase.
Thus, the correct answer is - at the G1/S phase and G2/M phase.
C, energy
to regenerate ATP is the chemical energy stored in food like glucose
The answer is false for this question
Answer:
Bonding.
Explanation:
Bonding prevents complex or macro-molecules from spontaneously and rapidly degrading into atoms because force of attraction present between atoms. These bonds are very strong which is only breakable when there is high amount energy is supplied so we can conclude that bonding between atoms of complex molecules are responsible for their intact structure and prevent rapid degrading into atoms.
Covalent bonds share electrons between two atoms.
