Otitis media is an acute infection of the middle ear. It is caused mainly by bacteria and is associated with nose and throat infections. The causative bacteria pass into the auditory tube from the nasopharynx and cause infection in the middle ear. There is a build-up of a large amount of fluid interstitial fluid in the tympanic cavity resulting in reddening and bulging of the eardrum.
Children have almost horizontal auditory tubes that decrease drainage and therefore, are most likely to become affected. To treat the condition, a small tube is inserted into the eardrum to provide a pathway for the drainage of the fluid.
The answer would be A because if they are raised where every th ing is given to them they don't know how to do the normal functions they do naturally by themselves like hunt or maybe migrate.
The majority of genes carried in a cell's DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.
