Answer:
The given image shows - the Stomata that helps in maintaining homeostasis in the plants.
Explanation:
Stomata are the small structure resemble as tiny or pinholes that found on the underside of the leaves and play many roles in the plant. Stomata help in the gas exchange and also helps in transpiration. It allows oxygen a gas and water in vapor form from the leaves to the outer environment and let carbon dioxide inside the cell.
This system also helps in transpiration by closing and opening stomata with the help of their guard cell by becoming turgid and flaccid by osmotic pressure.
Answer:
Choice A, Adhesion
Explanation:
If you have trouble telling the difference between cohesion and adhesion, remember that an adhesive is glue, water is essentially "gluing" itself to another surface.
It is the second option
Gg symbolises green color(because G is dominant so it will be green) and GG symbolises yellow( as there is no dominant trait present)
This would impact the food chain. The smallest disruption causes drastic changes within an ecosystem.
Answer:
a mutation that blocks the GTPase activity of Ras
Explanation:
A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
