Over time, natural selection eliminates individuals with detrimental phenotypes from a population. however, there are several examples in the human population in which harmful genetic polymorphisms are maintained. why? a. individuals with two wild type alleles have advantages over individuals carrying the harmful allele. b. individuals with two harmful alleles have advantages over individuals carrying one copy of the harmful allele. c. homozygous individuals have some other advantage over individuals with two wild type alleles. d. heterozygous individuals have some other advantage over individuals with two wild type alleles.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
