I hope it helps!!!
Answer:
is a thick band of neural fibers enabling communication between the two brain hemispheres.
Explanation:
A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.
The human brain consists of various sections and these includes;
I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.
II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making
III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.
The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.

Answer:
The correct answer is b. likely to be found in beta turns.
Explanation:
Proline is the amino acid which is unique from other amino acids as the side chain of proline is connected which gives it a cyclic structure. Beta turns are the secondary structure found in proteins that helps in the changing of direction of polypeptide chain in the protein.
The amino -acid proline is commonly found in beta turns because the unique cyclic structure of proline suits the beta-turn organization. Glycine is another amino acid that is abundant in beta turn because of its small size.
Therefore the correct answer is b. likely to be found in beta turns.
