The myogenic mechanism is one part of.
a. the osmotic gradient
b. hematopoiesis
c. tubuloglomerular feedback
d. renal autoregulation

D. Renal autoregulation.

Explanation:

It is a mechanism that is responsible for maintenance of relatively constant renal blood flow and GFR i.e glomerular filtration rate. It is the ability of the blood vessels to resist stretching during increased arterial pressure, a mechanism called myogenic mechanism. Whenever there is increase in blood pressure, the walls of arteriole tend to stretch. The wall of afferent arteriole in the glomerulus however responds to the stretch by contraction i.e. the diameter is reduced. This increases the resistance to flow, thereby reducing the GFR and renal flow during high BP.

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.
