Answer:
According to avogadro's law, 1 mole of every substance contains avogadro's number
of particles and weighs equal to its molecular mass.
To calculate the moles, we use the equation:
a. moles in 14.08 g of
= 
molecules in 14.08 g of
= 
b. moles in 17.75 g of NaCl = 
molecules in 17.75 g of
= 
formula units 17.75 g of
= 
c. moles in 20.06 g of
= 
formula units in 20.06 g of
= 
1. antibody
2. antigen
3. leukocyte
4. phagocytosis
5. dehydration
It depends on the function and activity of both cells. Most normal cells crease division if they came into contact with other cells however the immune system interact directly with pathogens or foreign organisms to destroy them.
