When smaller molecules are bonded together to create larger ones, the smaller molecules  are called  monomers and the larger molecules that they build are called polymers

Explanation:

Monomer is a relatively small molecule that can form covalent bonds with other molecules of its type to form a polymer. Polymer is a relatively large molecule consisting of a chain of many identical monomers chemically bonded to each other.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

the answer is sex-linked recessive.
