Answer:
Generally, aquaporins are found in the membranes of plants and also in the membranes of animals. It is a transporter, which takes part in mediating or regulating the flux of water across the membranes. A cell expresses the aquaporin protein due to many factors:
1. They function as sensors of gradients in turgor pressure and osmotic potential.
2. Aquaporins can assist in regulating and maintaining water permeability in response to different stresses like salt, drought, chilling, and others as water can move at a much greater speed through aquaporins.
3. Aquaporins can help in the movements of carbon dioxide, H2O2, NH3 through the plasma membrane briskly. Thus, the expression of aquaporin is essential for various species.
Stratus clouds have "layers" and look like they've been chopped up into many pieces. They produce Drizzles, and snow grains, and can only go up to an altitude of 6,000 ft. Cirrus cloud are similar to stratus clouds, but they are thinner and spread apart. They start at an altitude of 16,000 ft. I hope this helped ^^
One function that determines when and if cell division takes place is the activation of growth hormones.
Answer:
When plants are not watered properly they wilt. This is because of something called turgor, which is water pressure inside the cells that make up the plant's skeleton.
Hope this helps!
The cytoplasm that surronds the nucleus of a neuron is called the <em>perikaryon</em>.
