Answer:
The correct answer is "the S layer may play a role in protecting cells from viruses and predatory bacteria found in nature but not in laboratory cultures".
Explanation:
The S-layer (surface layer) is a part of the cell's envelope comprised of of identical proteins or glycoproteins that could be found in archaes and some bacterias in nature. The function of the S-layer is unknown, however the fact that is only seen in nature suggest that it may play a role in protecting cells from viruses and predatory bacteria found in nature but not in laboratory cultures. It is likely that archaes and bacteria synthesize the S-layer when they recognize viruses and predatory bacteria in nature, the S-layer is not synthesized in laboratory cultures because these pathogens are not present.
Some individuals are more likely to survive and reproduce than others because they are fit and easily adapting. This idea is called 'survival of the fittest'.
Answer:
<h2>They provide a 3’ end for the DNA polymerase.</h2>
Explanation:
Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.
Polymerase chain reaction was invented by Kary Mullis in 1983.
Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.
Answer:
Variola virus.
Explanation:
Smallpox is caused by a virus named as Variola virus.

↪ I think its from 6%-10% of living organisms today that will become fossils
↪ Animals have a less likely chance since they have parts that are difficult to become fossils (like teeth, bones)
↪ Plants may decompose and go underwater to be used as Crude Oil
↪ Most of the population are humans, which will be extremely hard to fossilise
