Assertion (A): The terminal branches of the axon of one neuron lie very close to the dendrites of another neuron.
Reason (R): : If there were a big gap between the axon and dendrites of two connecting neurons, impulses or messages would not be transmitted from one part of the body to another.

Answer
Both A and R are true and R is the correct explanation of A.
Reason — A is true as the axon terminals of one neuron are located very close to the dendrites of another neuron, forming a synapse. This close arrangement allows nerve impulses to be transmitted efficiently.
R is true as if there were a large gap between the axon and dendrites, nerve impulses could not be effectively transmitted from one neuron to another, disrupting communication in the body.
Therefore, Both A and R are true and R is the correct explanation of A is the correct option.

Assertion (A): The life of living beings is dependent on a number of processes going on in their bodies like digestion, respiration, etc. All these processes are inter-related to fulfil the general needs of the body.
Reason (R): Living beings obtain the simplest forms of food after digestion and this digested food is burnt during respiration which provides energy. So, only two processes — digestion and respiration are enough for the survival of living beings.

Assertion (A): Nervous system and chemical coordination in human beings are functionally related to each other.
Reason (R): Nervous coordination is mainly regulated by brain, spinal cord, nerves and sense organs whereas chemical coordination is controlled by the chemical messengers called hormones. They both work in proper coordination.

Assertion (A): The cerebrum is the seat of intelligence, consciousness and will power. It controls all voluntary activities of the body.
Reason (R): Cerebrum is the largest portion of the brain which accomodates a large number of neurons. Hence, it controls all the internal and external activities of the body, whether voluntary or involuntary.

Assertion (A): Sympathetic and parasympathetic systems are the two parts of autonomic nervous system which are independent in their functioning and are not related to each other at all.
Reason (R): Both of these nervous systems are opposite in their actions. Sympathetic nervous system accelerates the actions while parsympathetic system relaxes them.
