. Landfill are is a/an: (a) open area (b) high lying open area (c) open area near a river/lake (d) low lying open area
anyanavicka [17]

Answer:

d

Explanation:

Landfills are low-lying open areas specifically designed for the dumping of waste materials to be buried later.

Landfills can be for municipal/household wastes, industrial wastes, or for hazardous wastes. They are usually low lying to facilitate their burial after they must have been filled-up and they represent one of the oldest methods of disposing wastes.

<em>Landfills are not just open areas, they are low-lying as opposed to high-lying, and they are not created near rivers or lakes.</em>

<em>The correct option is, therefore, d. </em>

andriy [413]

Answer:

The correct answer is B. the two strands of DNA must separate.

Explanation:

DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.

The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.  

After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.
