This interaction process is an example of epigenesis.
Epigenesis is processes in which living organisms such as plants, animals and fungi grow from a seed, egg or spore through a series of steps in which cells differentiate and organs form. The theory of epigenesis which was created by C. F. Wolff claimed that structures emerge during development that are not initially formed.
HI there!!!!!!
It would probably be the heart, brain or our muscles; they are constantly working !
I believe A is the most correct (i assume it's about antibiotics - they actually DO harm our immune system in some way).
B is partially correct because, the colds indeed should be treated by anti-viral medication (because the virus is a cause of typical cold) but using antibiotics during recovery is needed only when an additional bacterial infection occurs as a complication after the viral infection. and it doesn't happen very often.
C - what works? antibiotics doesn't work for viral infections (colds). anti-viral medication do.
D i won't discuss.
I am sorry for a so long answer. but your question is so linguistically twisted that i am not sure which of the following choices is actually correct because of a big amount of mistakes.
