<u>Answer</u>:
True - Homeostasis is regulated by two systems; the nervous system and the endocrine system.
False - Hormones released by the endocrine system are secreted through ducts.
The endocrine glands release hormones directly into the blood.
False - Steroid hormones bind to receptors on the surface of a cell.
The steroid hormones bind to nuclear receptors after they diffuse across the plasma membrane.
True - Hormones affect almost all cells and processes.
The effect of hormones are widespread and diverse. They control and integrate major processes in the body such as reproduction, development, the mobilization of the immune system etc.
False - Peptide hormones travel to the nucleus of a cell.
Peptide hormones never enter the target cell, They bind to a an external receptor on the membrane surface.
Other crystals can be similar or same shape.
What are you saying. anyway it is metal and rock like substances
by growing tress and by putting down hydro mulch as needed
Competitive inhibition vs allosteric inhibition
In competitive the substrate and inhibitor bind at the same active site - pretty straightforward. In allosteric regulation (speaking specifically about inhibition here), the inhibitor is binding at a site other than the active site, and changing the enzyme in some way to make it inactive.
