Answer:

Nitrates increase the growth of algae in surface water bodies, killing fish.

Explanation:

Nitrates are used by algae as <u>a food source</u> and their excessive supply can result into <u>uncontrolled growth of algal biomass</u>. The phenonmenon of excessive growth of algae in a lake environment is known as <u>eutrophication</u>. When the growth of algae keeps increasing, it results into low sunlight penetration in the water body especially in deeper zones. Therefore, organsims inside water will consume all oxygen and the lack of oxygen will result into their death including fish population. Keep in mind that <u>nitrates are not directly toxic</u> to the fish or other animals. Instead, some studies have argued that nitrates are beneficial up to a certain limit.

Researchers test a group of cells for DNA content immediately following mitosis and find the average to be 12 picograms of DNA p
zlopas [31]

Answer:

The correct answer is - 24, 24

Explanation:

In any type of cell division, there is an interphase stage before the actual process of division which is a preparatory process or stage that includes different substages like G1, S, and G2. S phase is a synthesis of the cell cycle responsible for duplication or replication of the DNA.

So, at the end of the S phase, the DNA amount becomes double its initial amount and remains the same in the G2 phase. So, if the initial amount is 12 picogram then it will be double in the S phase and remain 12 in G2 as well.
