Answer:
The answer is exogenous/non-self signals.
Explanation:
- All types of stimuli that trigger certain responses from cells are broadly classified into two categories:
- Self/ Endogenous Ligands
A ligand is a carrier molecule that can binds to a stimulus, thus, producing a signaling molecule. Ligands bind to specific receptors in or the surface of the cell.
Self/endogenous signals are signaling molecules produced by the body itself. They are part of normal cellular communication.
2. Non-self/Exogenous Ligands:
These are signals produced by a foreign source such as a pathogen or a drug administered into the body. Basically, any signal that is foreign to the body and not produced by the body itself are exogenous ligands. Exogenous ligands elicit an immune or allergic response in the body. When identified, these ligands and their source is attacked by the immune system.
They are better adapted to the environment. Their darker color helps them blend in with the tree bark so common in their habitat. Because of that, more are likely to not get eaten by predators than white ones that are so easy to spot without camouflage abilities. The black moths are simply more fit to survive, and more of them will survive in this place.
The image of a point is B'(-4, 11). A 180° clockwise rotation was performed to get this image. What were the coordinates of the pre-image?
(4, -11)(11, 4)(-11, -4)<span>(4, 11)</span>
Answer:
The small opening present on the epidermis which helps with exchange of gasses and transpiration is called stomata. Since most of the water (90%) is lost through stomata it regulates the level of excess water in the plant.

There's two things that will happen as a result of decreased fresh water income in the Mono Lake:
1. Salinity will increase; as the amount of freshwater will decrease, the Mono Lake will experience increase in salinity of its waters, which will be caused by the lower amount of incoming water and the big evaporation because of the high temperatures.
2. Dry out; the lake will eventually dry out, and that will be due to the bigger evaporation of its waters in comparison to the freshwater that's entering into it.
