m=7/-8
Explanation:
Gradient means that slope.
m= y2-y1/x2-x1
m=8-1/-3(-5)
m=7/-8
welcome
Answer:
The chemical receptors of cells have been defined as molecular structures to which other molecules considered as chemical messengers (neurotransmitters, hormones and other neuroactive molecules) specifically bind.
Chemical receptors can be located on the plasma membrane into which they insert by crossing it. Membrane domains have been defined for them and also on both sides of the membrane. The one on the external side corresponds to the binding site for messengers that come from other cells, a situation that defines the so-called heteroreceptors. If messengers coming from the cell itself join that site, the so-called autoreceptors are defined.
But chemical receptors can also be located inside cells. They are intracellular receptors and are found in the cytoplasm or in the nucleus. Messages act on them, which due to their chemical nature can cross the plasma membrane, such as steroidal hormones, thyroid hormones and neurosteroids

Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
Answer:
"My child will be asked to stand upright, arms stretched above the head."
Explanation:
The adolescent client should be leaning forward at the waist with arms hanging down; upright with arms stretched above the head would not allow proper screening.
