As air cools, its capacity to hold moisture reduces. This is is why as warm humid air cools, it reaches a saturation point, and the water moisture begins to form droplets. These droplets form clouds in the atmosphere.
Answer:
Low,cell,increase,decrease,volume,pressure,Renin,negative
Explanation:
It is synthesized when blood pressure is low or cell division is activated.It causes increase in resistance and decrease in fluid output(which helps to maintain blood volume and blood pressure) and an increase in blood volume(if fluid intake occurs). Consequently,blood pressure increases.This is aided by the release of both renin and aldosterone.As the blood pressure returns within its normal homeostatic levels,both renin release and angiotensin 2 synthesis are decreased by negative feedback.
Answer:
