Answer:
The correct answer will be option-accurate and complete DNA replication.
Explanation:
The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.
The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.
Thus, option-accurate and complete DNA is the correct answer.
By boiling liquids, pasteurisation of milk, appplication of salt, canning, drying to remove water, freezing to reduce bacteria growth and so on.

Answer:
b, d, and f
Explanation:
The transition from aquatic lifestyle to land posses some problems to plants; these include;
- <em>Water conduction and food distribution problem</em>
- <em>Desiccation problem</em>
In order to firmly establish in the terrestrial environment, <u>plants need to be able to obtain the water necessary for their metabolic activities and be able to distribute manufactured food from the various sources of production to other parts of the plant body.</u> This is overcome by the development of conducting tissues in the form of phloem and xylem. The xylem is used to conduct water from the root to the body of the plant while the phloem is a tissue used to conduct manufactured food from the point of manufacturing round the necessary parts of the plant.
<u>Plants also face the problem of heat and the risk of desiccation on land</u>. The development of waxy cuticle takes care of this problem. The waxy cuticle acts as an insulator on leaves and other organs of the plant and thus protect them from desiccation.
Correct options: b, d, and f
These pairs are found in double strand of DNA and RNA where the bonds between them connect the two strands making the double stranded structures possible.
