Answer;
-Presynaptic neuron
Explanation;
-When a nerve impulse travels from neuron 1 to neuron 2, neuron 1 is known as the presynaptic neuron.
-This is a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
- A postsynaptic neuron is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a neurotransmitter from the axon terminal of a presynaptic neuron.

The answer would be A
Explanation:
I took the test last year
Answer:
D. Alternative splicing is the mechanism that produce complexity in the genes by splicing some of the protein coding part (exons) of a genes
Explanation:
There are certain splicing enhancers sites present in Exons which facilitiates the binding of RNA binding protein specifically SR protein family rich in Serine and Arginine residues. This SR protein will help in splicing of exons.
The significance of this type of mechanism is the ability of a cell to produce an isoform of protein which have retain their function.
This mechanism also help is diversity or in short in evolution.
Answer:
Carbon dioxide and oxygen can't pass through the cuticle, but move in and out of leaves through openings called stomata
