4. There are a variety of receptors and second messenger systems in cells that in many cases exhibit cross-talk with each other (the activation of one can influence the behavior of another). Given this fact understanding how ligand activated receptors works is not as easy as presented in your book or in class. a. There are a number of different ligands that interact with their respective receptors. How do receptors for testosterone, ferro transferrin and Fibroblast Growth Factor differ from each other with respect to the location and function of their receptors

These 3 receptors are different from each other. They do differ from each other by their location and function.

1. Testosterone receptor :  It is an Androgenic receptor

2. Ferrotransferrin receptor :  It acts as an element-binding protein which is iron responsive.

3. Fibroblast growth factor :  It acts as a growth factor.

Explanation:

1. Testosterone :

Location- Xq 11-12 in the X chromosome.

Function-  

2. Ferrotransferrin :

Location- chromosome 3q21

Function-

3. Fibroblast (growth) :

Location- chromosome 4p16.3

Function-

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

not sure if this what   you'r looking for would be percent composition
