A is your answer. When only one parent produces the offspring, they are essentially cloning themselves, and it is called asexual reproduction. The offspring only have the genes of the one parent. A lack of genetic diversity is one of the drawbacks to asexual reproduction.

The ______________________ picks up whole and partial neurotransmitters from the synaptic gap and brings them into the terminal

Verdich [7]

The vesicles pick up whole and partial neurotransmitters from the synaptic gap and bring them into the terminal button, where other structures recycle these neurotransmitters for future use.

Within the presynaptic terminals is where the synthesis of the small-molecule neurotransmitters takes place. A process known as slow axonal transport is responsible for moving enzymes from the neuronal cell body to the cytoplasm of nerve terminals at a rate of 0.5–5 millimetres each day. These enzymes are necessary for the production of transmitters and are produced in the neuronal cell body. Transporter proteins, which are typically located in the plasma membrane of the nerve terminal, are the ones responsible for bringing the precursor chemicals that these synthetic enzymes use into the terminal. Enzymes produce a neurotransmitter pool in the cytoplasm, which must then be loaded into synaptic vesicles using transport proteins in the vesicular membrane. Within the synaptic vesicles, the final synthetic steps of the production of certain small-molecule neurotransmitters are actually carried out.
