Right receptor protein on the surface of the target cell or in cell plasma is required. There are three major types of receptors in cell:
1. Channel receptors- <span>neurotransmitters.</span>
2. Receptor tyrosine kinases-protein expression
3. G protein coupled receptors-<span>detect </span>substances<span> outside the </span>cell
Answer:
The crabs with white shells. The next generation of crabs will be white shelled.
Explanation:
The crabs with white shells are more likely to survive because they blend in with the white sand more than the ones with brown shells making it easier to hide from predators and also makes it a desired trait.
The right answer is water.
A solution is a liquid containing several constituents
* The majority constituent is called solvent. Most often consists of water, the solution is called aqueous solution.
* The substances in solution are called solutes.
* The species in solution are either molecules or ions.
If we add water in the aqueous solution, we will have a dilution. On the contrary, if we add solute or remove water (pure water in solutes) we will have a concentration.
Answer:
Ice cores drawn from Antarctica, Greenland, and tropical mountain glaciers proves that Earth's climate responds to changes in greenhouse gas levels. You can also find ANCIENT evidence in tree rings, coral reefs, layers of sedimentary rocks, and ocean sediments.
( re word it to however you would've said it if possible.)
Explanation:
I learned about this already, and had to do deep research when I did.
