False????
Negative feedback mechanisms are the primary types of mechanisms we use to maintain homeostasis. In these, the output will act to:
act to reverse or shut off the stimulus
Which system(s) forms the communication or “feedback” loops to maintain homeostasis?
endocrine system & nervous system
This passive transport process uses carrier molecules in the membrane to transport large substances, like glucose, from high concentration to low concentration.
facilitated diffusion
Identify small, lipid soluble molecules passively diffusing across the cell membrane.
oxygen, steroids, alcohol, carbon dioxide
This simple epithelial tissue consists of cells that vary in height and is found lining the upper respiratory tract.
pseudostratified epithelium

If blood glucose is low, what must the body do to return to homeostasis?
release a hormone (glucagon) which acts to raise blood glucose levels
