Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color.

Eye color
height
skin color

It might involve changing to survive different temperatures such as when lakes freeze over or a lake is too hot.
Susceptibility refers that they can not grow if drug is present . Antibiotic is effective against the bacteria. Resistant means the bacteria can grow even if the drug is present and this sign is an effective antibiotic.
The antibiotic susceptibility testing are based on measuring the inhibition of growth of bacteria. Average time which requires to obtain result are 18- 24 hours for rapid system.Antibiotic sensitivity test can help in finding that which antibiotic is more effective in treating infection accordingly.
Antimicrobial susceptibility test is very significant bacterial isolates and there goal of testing is to detect possible drug resistance in common pathogen to assure susceptibility to drug of choice for particular infections.
