Answer:
The principal reason for the increase of groundwater use is the increasing population. Urbanization and pollution have both contributed to an increase in the use of groundwater. Polluted rivers, lakes, and springs are no longer viable sources of groundwater.
Explanation:
Stomata
1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Hope it’s correct
The phenotypes of snapdragons of F1 generation had pink flowers only.
Explanation:
The crossing of snapdragon with red flowers and white flowers as well led to the production of F1 offspring of hybrid quality having pink flowers only. This F1 phenotype under goes pollination and results in F2 phenotype with a ratio of 1 red, 1 white and 2 pink flower.
This is incomplete dominance as the phenotypes of parental plant, as in the white and red flowered plant reappear in the F2 generation.
Answer:
C. Co-evolution
Explanation:
In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution
