Answer:
a.There are three signaling pathway
1- Reception in which molecule binds to receptor
2- Signal transduction in which activation of intracellular pathway and enzyme occur.
3- Cellular response in which specific response of cell occur according to receptor and ligand.
b. Three types of receptors are
1- autocrine
2- paracrine
3- endocrine.
Explanation:
autocrine receptors are signaling pathway in which cell releases its molecule and bind to its own cell receptor example cancer cells while paracrine in which ligand binds to other nearby cell receptor and it is used during development and in endocrine cell target distinct cell and travel through blood stream like hormones functioning.
Explanation:

The fish is the limiting factor because its population <u>determines the survival and availability of the grizzly bears.</u>
A limiting factor is resources(biotic or abiotic) that affects or determine the availabity and growth of an organism or group of an organism within an ecosystem.
The more fish it takes, the more the liver produces urea, and kidney tubules makes use of the urea in it tubules for urine formation in the loop of Henle. The urine formation and loss, leads to intake of water and the sequence continues.
This is an example of a biological limiting factor because the bear predate on the fish for survival and population.
If the population of the fish drops,( <u>the limiting facto</u>r) the bear drinks less water based on above, and therefore <u>disruptions of the ecosystem</u>.
