Answer:
B) if two species are closely related.
Explanation:
DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.
. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. ... Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.
Answer
Complex barrier to the flow of substances out of the cells,and restrictions to inflow of unwanted substances into the cells. The hydrophobic and hydrophilic nature of the cell membrane controls the entry of substances from the extracellular medium into the intracellualr. In addition the polarity restricts certain substance movement across the walls.
Serve as the selective channels for the influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.
Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.
Separation of metabolic process in the cell.
Explanation:
Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its constituents, it is made up of lipids, carbohydrate, protein and cholesterol
Hey there,
Step 1: N<span>ever attempt to remove a patient from an electrical source unless the EMT is trained and equipped to do so.
Step 2: </span><span>Never touch a patient who is still in contact with the electrical source
Step 3: </span><span>Administer oxygen by nonrebreather mask at 15 lpm
Step 4: </span><span>Monitor the patient for cardiac arrest
Step 5: </span><span>Assess the patient for muscle tenderness with or without twitching and any seizure activity
Step 6: A</span><span>ssess for an entrance and exit burn injury
Step 7: T</span><span>ransport the patient as soon as possible.
Hope this helps :))
