Normally two copies of each chromosome (diploid) are found in most animal cells. The only animal cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome (haploid). When two reproductive cells unite, they become a single cell that contain two copies of each chromosome.

Kruka [31]

I think most of the environmental pressure will come from pollution, and a lack of space. With so many people around, there''s going to be a lot of vehicle use, and things such as littering. We're going to have to change and start cleaning up after ourselves and limit the use of gas.

The pressure in the past will be: raising temperature and flooding, more Co2 in the atmosphere.

We might for example evolve to better extract the oxygen from the atmosphere and be better resistant to heat.

Answer: I believe that the environmental pressures that exist now and that may be shaping the human species are the use of land, the extraction of resources, greenhouse emissions and water use. This are being used by use more and more as we start overpopulating the earth.

The chemical shown in the image which is released to the nearby cells is signaling molecules that interact play an important role to induce the change in the cell function as per the chemical signal molecule and internal condition.

Signal molecules bind to the receptor present on or in the cell and change confirmation to initiate the gene expression more specifically translation and produce the proteins that result in different cell functions.

Primary function of the signaling molecules is to start protein production in nearby activated cells.
