For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
Answer:
<h2>
A
</h2>
Explanation:
1. A channel between two adjacent cells in known as an intercellular cleft.
2. And through these channels many molecules can easily pass between cells.
3. Importance of Intercellular clefts:
i) It is very important in transportation of fluids and small solutes.
ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.
Could you give us some more information?

am i supposed to put something here??????
also if u get it wrong bc of me im sorry :(
Answer:
By decoding information with the help of transfer RNA (tRNA).
Explanation:
The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.
