Answer:

It is because sedimentation will more often occur in marine ecosystems

Explanation:

Formation of fossils (through the process of fossilization) is a rare event because animal bodies are often eaten and decayed (destroyed by scavengers and decomposed by worms). But, fossilization can be achieved after the quick burial of an animal.

So, for example, dead marine animals might be buried by sediment that is carried by the water. Also, sediment can precipitate on the ocean floor, covering the remaining of dead animals.

Which is NOT a potential threat or danger to an ecosystem rich in biodiversity? A) Deforestation B) Plate Tectonic Activity C) G
IrinaK [193]

The correct answer is option D, that is, genetic diversity among the species.  

The sum of genetic characteristics in the genetic makeup of a species is known as genetic diversity. It is differentiated from genetic variability that illustrates the capability of genetic features to change.  

The genetic diversity functions as a medium for the populations to amend with the fluctuating environments. With more changes, there is more possibility that some individuals in a population will exhibit different forms of alleles, which are appropriate for the surrounding.  

These individuals hold high possibilities of survival in order to generate offspring exhibiting that allele. The population will continue for more generations due to the accomplishment of these individuals.

Why can't you prescribe antibiotics to treat a viral infection???!!!!!

Hence, it is difficult for antibiotics to target and destroy viruses without harming patients, rather antiviral drug are prescribed against viruses
