Explanation:
An ecosystem that contains a high degree of biodiversity will have numerous organisms of different species. According to the question, sharks are stated to feed on a wide variety of prey. This means that sharks can feed on any other species of organisms at lower trophic levels.
In a situation whereby an ecosystem contains a low degree of biodiversity i.e. low variety of species, the sharks will have to consume a large numbers of a key species, which will cause the ecosystem to lose stability.

Answer:
Too much light can make the specimen impossible to see under a microscope
An unknown mtDNA sample sample is matched to a sample of mtDNA that was found at the crime scene.<span> This is how mitochondrial DNA (mtDNA) typing is used in forensic science.</span>
<span>Unlike nuclear DNA typing, mtDNA isolation is quite easy because its number is quite large. mtDNA copies rang from 100 to 10,000 per cell. It is also more stable and stronger than the nuclear DNA; that is why even unsolved cases from years ago use mtDNA typing as reference for possible conclusion.</span>
