Answer:
Option-B
Explanation:
DNase I is an enzyme which acts on the DNA in its single-stranded, double-stranded and chromatin form.
The DNase acting sites on the DNA is known as the DNA I hypersensitive site. The DNase I hypersensitive site allows the DNase I to act as the condensed form becomes less condensed. This mechanism can be associated with the transcription as, during transcription, the DNA becomes less condensed and is open to DNase I enzyme.
Thus, Option-B is correct.
Answer:
An oxbow lake forms when a river creates a meander, due to the river's eroding the bank. After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck during a flood, cutting off the meander and forming an oxbow lake.
The answer is a mass extinction of the dinosaurs.
65 million years ago the mass extinction of the dinosaurs spurred mammal diversification. Before that, dinosaurs were big reptiles living on the Earth. They occupied many ecological niches. But, after the extinction, they made room for other animals, such as mammals, to evolve and rapidly diversify.
