Answer:
Biological species concept explains the concept of speciation. According to this concept species are the group reproductively isolated individuals that can breed among themselves.
The species concept in the forest can directly be observed by observing the type of the mating natural environment in two different group of organisms. The two different forms if do not mate with each other then it can be consider that they belong to the different species.
Answer:
<em>The correct option is B) DNA fragments are negatively charged.</em>
Explanation:
The backbone of the DNA is made up of sugar and phosphates. The phosphates present in the backbone of the DNA are the main reason for the DNA to be negatively charged. The negative charge of the DNA allows different DNA fragments to separate by gel electrophoresis depending on their charge/mass ratio. The smaller DNA fragments will move faster towards the positive end of the gel as compared to the larger fragments and hence they will separate.
