The disadvantages-
*They are born with many typrs of diseases

<span>overall, around twenty million teenagers contract an STI (sexually transmitted infection) each year. </span>(The half of them are from U.S.)<span>
A sexually transmitted infection (STI) is an infection that is transmitted between partners during different forms of sexual intercourse. This infection can lead to an infectious disease, formerly called venereal disease (the name comes from Venus, goddess of love)All sexual practices that involve mutual genital or oro-genital contact with another person, or genital fluids, are considered to carry a risk of transmitting an STI. Each STI has a different risk and severity.

A) The answer is allosteric interaction where activators or repressors bind to a protein, other than the protein active site, hence changing the protein conformation. This interaction occurs between the heme subunits of haemoglobin.
b) Through protonation. The amino group of the alpha subunits and the histidine C-terminal of beta subunits acquire H+ when the blood has low pH. Low pH in the blood is due to accumulation of carbon dioxide and consequent formation of carbonic acid. Protonation of the residues cause allosteric interaction, due to ionic interaction, of the subunits hence resulting to conformation change of haemoglobin between T-state and R-state
A fossil record is evidence for evolution because you can compare the fossiles to see the difference. You can tell how "survival of the fittest" played a part, and what characteristics the species had to help them survive in their environment.
