Answer:
Options A, B, E, and F are correct
Explanation:
A). In the cell cycle, DNA replication is a process by which a duplicate DNA strand is produced with the help of replication machinery (enzymes, nucleotides, etc.). The overall process ensures that the newly developed strand is free of any mutations (errors) causing the production of wrong proteins at later stages. Although, there are chances of positive, negative or neutral mutations, the replication machinery aims to avoid any such errors at this stage.
B). DNA stores genetic information in the form of codes (known as codon) which needs to be translated in the form of proteins. This process is known as a transcription by which messenger RNA (mRNA) is produced in the nucleolus. Thereon, it is transported outside to encode proteins with the help of ribosomes. The process of copying genetic information on DNA in the form of mRNA is known is transcription.
E). The figure shown is also known as the central dogma of life. According to which, DNA (genetic information) is transcribed into RNA, which is then translated to proteins. In brief, RNA molecules brings the information from nucleous to ribosomes and make proteins. These proteins are often enzymes, hormones, and other biomolecules that perform the important functions in living organisms.
F). DNA and RNA are two types of nucleic acids responsible for all types of life on Earth. Since both of them are well recognized as nucleotides, they are made up of the same genetic building blocks known as nucleotides. Further, each nucleotide is comprised of a five-carbon sugar, a phosphate group, and a nitrogen base. The sequence of these nucleotides is responsible for the production of specific types of proteins.

Explanation:
Answer:
To absorb neutrons before the neutrons can initiate more fusion reactions.
Explanation:
Control rods, usually made of compounds like graphite, absorb neutrons and prevent them from going everywhere and bombarding other molecules of the radioactive compound being used, usually U-238, and prevent a chain reaction from starting. When U-238 is bombarded with a neutron, it releases 3 others, which hit 3 molecules of U-238, releasing 27 neutrons in total, and so on. This must be controlled, otherwise an uncontrolled chain reaction could easily become highly explosive (Nuclear bombs that utilise U-238 use this principle to cause a chain reaction at a larger scale that releases huge amounts of energy that cause the initial explosion when the atom bomb is detonated).
The process by which oxygen and carbon dioxide are exchanged between the lungs and the atmosphere is known as respiration.
