Hey there!
The skin and nervous tissues develop from the ectoderm.
industrial pollution from factories, but to classify it would be air pollution.
Answer:
the cell membrane allows the solute to enter the cell which causes the cell to shrink.
Explanation:
cell membrane is semipermeable membrane, it selectively allows the movement of solute, water, salts, etc. in and out. when the solute enters the cell membrane it increased the solute concentration inside the cell. water gradient outside the cell wall decreased, hence water started to move outside from the cell membrane and causing the cell to shrink.
As the temperature decreases, the metabolic rate of an endotherm typically slows, and the metabolic rate of an ectotherm typically increases.
