<span>The correct answer is option A. Hydrogen bonds keep the two strands of DNA together by binding the nucleotides together. The hydrogen binding is repsponsible for the stability of DNA. The N-H bonding is the reason behind this between nucleotides base pairs of the DNA.</span>

<span>The appropriate response is hydrogen bonds. It is a feeble bond between two particles coming about because of an electrostatic fascination between a proton in one atom and an electronegative iota in the other. Intermolecular hydrogen holding is in charge of the high breaking point of water (100 °C) contrasted with the other gathering 16 hydrides that have significantly weaker hydrogen bonds.</span>

Galina-37 [17]

Answer:

C) commensalism

Explanation:

Commensalism is an interaction in which one organism benefits without causing any harm to the other. The other organism derives no benefit from the relationship.

The scenario above in which the dwarf mistletoe obtains nutrients from the vascular tissues of trees is a perfect example of such a relationship.

Parasitism is similar to this but the other organism is harmed in the process.

After duplication, at what point does a cell become two cells with identical DNA? starting in prophase end of anaphase end of cy
Fofino [41]

Answer:

The correct answer is - end of cytokinesis.

Explanation:

Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.  

During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA  

The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.

Thus, the correct answer is - end of cytokinesis.
