I would answer but you didn't put any pictures so I can't see what shows anything.
Answer:
Gel Electrophoresis is a way to sort and measure the DNA strands. Scientists use the technique whenever they need to sort DNA strands according to lengths, this is because it helps them determine patterns, banding patterns create a unique fingerprint for a certain individual. During the process, the shorter strands move faster because they have less mass compared to the longer strand. Therefore, the short strands end up farther away from the starting point than the longer strands, which is how the difference in lengths sort themselves out.
D.) Bioaccumulation is your answer.......
Answer:
<h3>Habitat isolation is responsible for causing speciation between the two species of garter snakes.</h3>
Explanation:
- Habitat isolation is a type of isolation in which two species are barred from mating or interbreeding due to the presence of physical barriers between them such as mountains, rivers, etc.
- Habitat isolation only can happen if two species occupy different habitats.
- Example- Gryllus pennsylvanicus prefer to live in those soil which has less water content like in sandy soil & Grylus firmus prefers to live in soil rich in water moisture i.e. loamy soil
