Answer:
The physical space between the presynaptic and postsynaptic neurons is called the synaptic cleft
and the chemical that is released to signal across this space is called a neurotransmitter
Explanation:
A synapse is the junction between dendrites of two adjacent neurons. Its function is to allow the transmission of nerve impulses from neurone to neurone. Tn the presynaptic knob there are vesicles which contain a transmitter substance which is usually acetylcholine. The acetylcholine diffuses from the presynaptic membrane to the postsynaptic membrane.

Answer:
The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
