<span>Apart from their habitats, Bacteria and Archaea differ in cell wall structure and membrane lipid composition. All bacteria have peptidoglycans in the cell wall whereas the archaea do not. Both also are different in RNA polymerases and thus in their protein synthesis. </span>
The student should chose a location within the office that has good ventilation and a workspace big enough to accommodate all his science materials.
What is an experiment?
An experiment can be defined as a procedure carried out under supervised conditions in order to discover an unknown effect, to test or refute a claim, or to illustrate a known law.
A science experiment should be carried out in a location within the office that has good ventilation and a workspace big enough to accommodate the required science materials. The location should be devoid of children, pets and other danger-posing objects.
In conclusion, experiments are carried out in suitable conditions and environment.

Answer:
The correct answer is - divergent.
Explanation:
A divergent plate boundary is plate boundary that is form by the sepration of the two distinct tectonic plates away from one another and result in the forming the ranges known as oceanic spreading ridges.
This type of plate boundary occurs due to the earthquack or volcanic erruption of from the mantle to surface of the earth. This magma or rises and forms oceanic crust by the solidifying of the moleten rocks.
Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.
DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.
