Answer:
a) Acetylcholine is degraded by acetylcholinesterase.
Explanation:
After it binds for its receptor on the plasma membrane of the postsynaptic cell, acetylcholine must be removed in order to prevent repeated stimulation. Acetylcholinesterase is enzyme for the inactivation of acetylcholine, present at all cholinergic synapses. This enzyme hydrolyses acetylcholine and breaks it to the acetate and choline. Choline can be reused for the synthesis of the new acetylcholine molecule so it is taken back into the presynaptic cell.
They both can expel water from the polymer network
Answer:
Option-B
Explanation:
Heredity refers to the passing of the traits from the parents to the offsprings or generation and also known as inheritance and Genetic variation is the difference in the genetic material in population which leads to the formation of a variety of traits.
Since the variation in traits is determined by factors (Gregor Mendel) later called "genes" which are passed on to the offsprings, therefore, the branch of biology which studies the pattern of inheritance and variation is known as "Genetics". Gregor Mendel is known as the Father of Genetics.
Thus, Option-B is the correct answer.
