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.
 
        
                    
             
        
        
        
Answer:
The "tail" of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water. Following the rule of "like dissolves like", the hydrophilic head of the phospholipid molecule dissolves readily in water. 
Nonpolar Fatty Acids

The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:
•	SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units. 
•	FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures. 
•	UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures. 
•	HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.
•	TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.
