Answer 1

1:- False

Reason:- Identical twins have the same copies oof gene but they do not have an identical brain because learning leads to anatomical changes in the brain. Due to the non-identical brain and non-identical intellect, the twins have different social experiences, learning and emotion.

2:- True

Reason:- Neurotransmitters are chemical messengers secreted from the presynaptic cleft that transmits informal from one cell to another cell which results in action potential and resting potential.

4- True

Reason:- The Limbic system is located near the thalamus under the cerebrum. The complex structure includes the hypothalamus, amygdala and hippocampus. It is responsible for the emotions and emotional behavior of the individual.

5:- True

Reason:- Amygdala is a part of the limbic system that access external stimuli like threats and then initiate appropriate action and response. It plays a significant role in emotions like fear, anger and anxiety.

6:- True

Reason:- A connecctome is an comprehensive map of brain that will allow us to understand anatomy, function and behaviour of human brain.
