vova2212 [387]
There are a lot of human activities that gives negative effects on the earth's ecosystem but I will mention only four: Burning of things such as garbages or plants and trees, dumping of garbages anywhere, chemical substance that are being made and produced, cutting down of trees for replacement of buildings and homes. The human activities increase the occurrence of species extinction by doing this, it eliminates and destroy the homes of the species that are supposed to be living on their natural habitat.

A hormone attaches to a target cell at a receptor protein. What do you know about this hormone?
charle [14.2K]
So, this hormone is a non-steroid hormone.  Steroid hormones are fat soluble and can pass directly into the cell to affect the nucleus.

Non-steroid hormones bind to the receptor and trigger a chemical change within the cell without ever entering the cell, or the nucleus.

The answer is: It will not enter the nucleus
