In
cell-cell contact , signals pass through a cell junction from one cell to adjacent cells.
Membrane-bound signals bind to receptors on adjacent cells in the process of
paracrine signalling.
An example of
autocrine signalling is when cells release signals that affect themselves and nearby target cells.
In
synaptic signalling cells release signals that affect nearby target cells. Cells release signals that travel long distances to affect target cells during
endocrine signalling.

Species diversity refers to the number of different species in an ecosystem or on the earth as a whole. This is the commonest way to measure biodiversity.
Answer:
<u><em>Initiation</em></u>
Explanation:
The first part of translation is initiation. So first an initiator tRNA molecule binds to a start codon in the mRNA. And then more tRNA's with amino acids attach to the mRNA strand according to the codons on the strand. Then the process continues.
