In a technical term, there is both small cells and large cells, but they are microscopic because they are what organic life is created upon. With cells, living creatures is possible. Cells are also small since there is such a large quantity of them, that they can be combined with other cells into a conglomerate that will synergize into a life form.
Also cells can be big, for example the egg cell within a female human can be as large as the head of a pin, which is absurdly large for a cell.
Hello, to answer your question properly the problem that's effecting the population is the decrease in trees. It causes their nests and homes in the trees to be burned and make them have to migrate somewhere else then that area they were living in.
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.
