1. Why pituitary gland is known as master gland?

Ans: The pituitary gland is called the "master gland" of the body because it produces hormones that regulate other endocrine glands. 

2. How do biological factors determine psychological behavior?

• Giving insight about hereditary factors to describe behavior. Example; Twins
• Many psycho-social phenomena like discrimination, prejudices, etc can be handled through biological processes.
• Various psycho-physical maladjustment can be relieved by understanding biological factors. Example; hypertension, drugs, heart disease, cancer, etc.

3. What is nerve impulse?

5. Write about a synapse.

Ans: Synapses are microscopic gaps that separate the terminal buttons of one neuron from receptors (usually, located on the dendrites) of another neuron. When neurons communicate, they release chemicals that must travel across this gap to stimulate the post-synaptic receptors.

6. Differentiate between the function of rod cell and cone cell.
