Answer:
C and E
Explanation:
A wavelength, when drawn like this, is between two points in the exact same spot of the wave, but in different positions. Here, C is the middle when the wave is going "down" into the trough. The next point at this position is point E, giving us our answer.
Answer:
Answer is C.
Explanation:
A. The vessel length is pretty much constant. The body can't length or shorten blood vessels.
B. Blood viscosity is also fairly constant because the composition of blood cannot change quickly enough to change resistance as needed.
C. This is the main way resistance is controlled. The smooth muscle surrounding blood vessels can rapidly respond to hormonal or metabolic stimuli and contract/relax to adjust diameter.
D. Again, temperature is fairly constant in the body and would not be a good way to alter resistance.
