Answer: The juxtaglomerular complex is a system that regulates the rate of filtrate formation and systemic blood pressure. This is made up of the distal convoluted tubule and the glomerular afferent arteriole. In the distal convoluted tubule, there are specialized epithelial cells (macula densa) that detect sodium concentration of the liquid in the tubule. Because of the increase in sodium, the macula densa cells activate the afferent arteriole’s contraction, which reduces blood flow in the glomerulus. In the afferent arteriole, there are juxtaglomerular cells which secrete renin when the blood pressure decreases.
Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells containing chlorophyll.
First off, both poles would have rapid expansion, with the freezing of more water near the poles.
Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
Deserts would expand and the average temperature would rise.
Also, many animals would also die out, because of the change in their environments.
Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.
