Answer:
A cap is added to the 5 end of the mRNA
Explanation:
In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.
One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.
Thus, the selected option is correct.
Chemical energy is the potential of a chemical substance to undergo a chemical reaction to transform into other substances. Examples include batteries, food, gasoline, and etc. Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system.

Answer:
they come from embryos, have properties of embryonic stem cells, Perinatal stem cells.
Explanation:
Embryonic stem cells. These stem cells come from embryos that are three to five days old.
Adult stem cells.
Adult cells altered to have properties of embryonic stem cells (induced pluripotent stem cells).
Perinatal stem cells.
Answer: Alarm reaction stage
Explanation:
The General Adaptation Syndrome (GAS) is the 3- stage body response to stress conditions. The three stages include
1) Alarm reaction stage
2) Resistance stage
3) Exhaustion stage
Note that the Alarm reaction stage consist of arousal by the autonomic nervous system, where several involuntary responses such as sweating, tension, raised breathing etc are observed due to hormones released.
