Answer:
the correct option is: 3. Hormones that interact with plasma membrane receptors that have a hormone binding site outside and an enzymatic activity on the cytosolic side, with ligand binding stimulating that activity.
Explanation:
There are about 200 differentiated cell types in humans, only a few produce hormones, but most of the 75 trillion cells in a human being are targets for one or more of the more than 50 known hormones. The target cell concept is a useful way to analyze hormonal action.
The cells have protein structures on the surface, where they are hormone-ligand, this generates different signal activation pathways inside the cell, through ion channels, g proteins, increase in internal cAMP, and other mechanisms.

Answer:
Adjust the light intensity until an image can be clearly seen. Change the microscope objective lens to the next highest power and repeat step 3. Once at the highest objective lens, you should see graduations that are equal to approximately 10 microns
Because most of the fungi were found in moisture places not the same to plants they will found everywhere.
