This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition

FromTheMoon [43]

Answer:

The correct answer is - B-DNA is the most common form of the DNA present in the cell and a good approximation of the structure of DNA in the cell.

Explanation:

The B- DNA is a form of the DNA that is explained by Watson and crick by the double-helical structure model. B-DNA is the predominant form of the DNA out of the three forms of the DNA which are B-DNA, Z-DNA, and A-DNA.

B-DNA is is provide a good approximation of the structure of DNA in a cell and its most common form of DNA in a cell that makes it the most studied and focused form of DNA.

Thus, the correct answer is -  B-DNA is the most common form of the DNA present in the cell and a good approximation of the structure of DNA in the cell.

Consider this situation: you want to reabsorb sodium ions but you do not want to increase the volume of the blood by reabsorbing
choli [55]

Answer:

Increase aldosterone and decrease ADH

Explanation:

Aldosterone causes reabsorption of sodium ions while Antidiuretic hormone (ADH) causes reabsorption of water. Aldosterone also causes water reabsorption due to increased osmotic pressure by reabsorbing sodium ions. But for water reabsorption, Aldosterone has to work along with ADH to increase permeability for water. If we increase Aldosterone and decrease ADH, the sodium ions will be reabsorbed while water cannot be reabsorbed due to decreased permeability of DCT and collecting tubules for water.
