The correct answer is fight or flight.
The fight or flight response also called acute stress response, is a physiological response to a perceived attack, threat or in general any stressful event. This reaction consists the first stage of the general adaptation syndrome, which is the mechanism that regulates the response to stressful situations.
This response consists of an activation of the autonomic nervous system and a cascade of hormones, including catecholamines, cortisol, estrogen, testosterone, and dopamine. This hormonal cascade results in many physiological changes which prepare the body for action.

Answer:
DNA replication is initiated by the help of these enzymes.
Explanation:
Helicase enzyme helps is unwinding the two complementary strand of DNA by hydrolysing the hydrogen bonds present between the nitrogenous bases of the two opposite strands.
Topoisomerase enzyme help in expansion of the Replication bubble by releasing the super coiling or tension occured while unwinding by helicase. It breaks the phosphate bonds in one of the two strands ahead of replication bubble or fork to release super coiling or overwinding.
Single-strand binding proteins gets bind to the separated strands to stabilize the structure of Replication bubble or to keep the both strand separated from each other.
Answer:
true
Explanation:
lactase is the enzyme that leads to the hydrolisis of lactose, when lactose is present the e coli needs to hydrolyse it to simple sugars so it needs to active the gene for lactase synthesis
