Dna replication
a. occurs through the addition of nucleotides to the end of the dna molecule.
b. results in the formation of four new dna strands.
c. produces two daughter dna molecules that are complementary to each other.
d. uses each strand of a dna molecule as a template for the creation of a new strand.
e. begins when two dna molecules join together to exchange segments

d

Explanation:

The mechanism of DNA replication is semi-conservative. The two DNA strands are held together by hydrogen bonds between the nitrogen bases of the anti-parallel strands. During replication enzymes like helicase, topoisomerase and SSB protein break the hydrogen bonds for a short period. During that period, RNA primers from cytoplasm pair with each strand to give rise to two daughter DNA.

So a daughter DNA has one strand from the parent DNA and one new strand from the RNA primer.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

option c is the correct answer.
