Answer:
The characteristic of water-soluble hormones are:
1. They dissolve in water and do not dissolve in fat or oil
2. They are produced from amino acids that are soluble in water
3. They will be unable to pass through cell membranes that have fatty molecules
4. They are receptor-specific. That is they bind to a receptor that fits them on the target cell.
Explanation:
The cellular communication is an important aspect of unicellular and multicellular organisms in the environment. The cellular communication may differ in the bacteria, plants and animals but the mechanism of cellular communication remains the same.
The mechanism involves the receptors, change in the structure of receptors which triggers the signal to respond and then the response of the cell. Therefore the evolutionary biologists must look at this mechanism and the molecules associated with this mechanism.
The biologist can look at these receptors and the ligands which initiate the transduction process in the organisms.
If the earth did not rotate, convection currents would move in one straight path, from the equator to the north pole and back again, the rotation of the earth causes this path to be skewed so that currents move in smaller circles between these areas, this is called the coriolis effect.
