Answer:
Effect on the cheek cells
Explanation:
An independent variable is something you change (ex. the amount of salt used). The dependent variable is the thing you are studying (ex. Cheek cells)
Answer;
-Positive charge
Prior to the arrival of a signal from a presynaptic input, the post-synaptic membrane is polar with a greater relative positive charge to the ECF
Explanation;
-Neurons talk to each other across synapses. In somatic neurons, an action potential arrives at the synapse causing synaptic vesicles to fuse with the presynaptic membrane. The pre-synaptic membrane releases acetyl choline via exocytosis into the extracellular of the synaptic cleft.
-The ACh diffuses across the cleft and binds to the ligand-regulated sodium channels. Activated sodium channels allow a rapid diffusion down its electrochemical gradient towards the ICF. The movement of positive charges to the ICT causes the relative charge across the membrane to become positive on the inner surface.

If you take these two problems, and then subtract, and find out the difference between the two distances, then you should be able to get your answer.

Vasoconstriction
Definition-The blood vessels under your skin become narrower. This decreases blood flow to your skin, retaining heat near the warm inner body.
