I believe your answer would be d
Given the statement "Most bacteria are heterotrophs." we could say that it is TRUE. Heterotrophs is a<span>n </span>organism<span> that cannot </span>fix carbon<span> and uses </span>organic carbon for growth and can be further divided based on how they obtain energy; if the heterotroph uses light for energy, then it is considered aphotoheterotroph<span>, while if the heterotroph uses chemical energy, it is considered a </span>chemoheterotroph<span>.</span>
Lethal alleles (also referred to as lethal genes or lethal) are alleles that cause the death of the organism that carry them. They are usually a result of mutations in genes that are essential to growth or development. Lethal alleles may be recessive, dominant, or conditional depending on the gene or genes involved. Lethal alleles can cause death of an organism prenatally or any time after birth, though they commonly manifest early in develop
Idk but u could search it on google or it might say it on a science book
