Because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis<span> also produces genetic variation by way of the process of recombination.</span>
The lens is the clear oval structure in the eye that focuses light as an image on the retina.
DNA, RNA, protein digesting enzymes did Avery, MacLeod, and McCarty use in order to identify the genetic material.
<h3>What is the Digesting enzyme of DNA?</h3>
- With the aid of specialized enzymes known as restriction endonucleases (often referred to as restriction enzymes or REs), restriction digestion is the process of breaking down DNA molecules into smaller fragments.
- Wherever that sequence appears in the DNA molecule, these specialized enzymes can identify specific DNA sequences (for instance, GATATC).
- The DNA and RE are first combined in restriction digests, but things don't work out quite that easily.
- Because they are fragile, restriction enzymes must be handled with care.
- Since proteins which are what enzymes are denatured when the temperature rises, REs are always kept in the freezer until they are needed.
- In actuality, the components of a Restriction Digest are all kept chilled until the reaction is ready to start.

The right option is B.) replicating experiments.
Scientists ensure that data is reliable by carrying out repeated experiments. When an experiment is replicated by scientists, its quality is evaluated and considerable confidence is added. Scientists endeavor for their experiment findings to be replicable in order to be sure that the experiment yields the same results/data when repeated by other scientists in different laboratories. If a finding cannot be replicated, it implies that the methods of testing are insufficient.
Answer:
By meiosis
Explanation:
By the process of meiosis, the diploid (2n) chromosome are halved into haploid chromosomes (1n) and The zygote receives only one of the male and female gamete (1n) to become a diploid (2n) zygote.
