The answer is; B
Mutations change the order of nucleotide and therefore affects codons that code for proteins. A different protein is thus produced from the wild type hence creating variations. Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.
Answer:
Animals, plants, fungi, and protists
Explanation:
Animals, plants, fungi, and protists are examples of Eukaryota organisms. Animal and plant cells contain many of the same kinds or organelles. There are also certain organelles found in plant cells that are not found in animal cells and vice versa.
Answer:
The first genetic code is used to determine the nucleotide triplets that code for amino acids.
Explanation:
The second genetic code is used by the amino acid synthetase in order to determine whether the correct tRNA is being used for it's corresponding amino acid.
Answer:
See the answer below
Explanation:
Person X is feeling a burning sensation in several muscles<u> because of the accumulation of lactic acid due to inadequate oxygen in their system.</u> When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.

Person Y does not feel any burning sensation in their muscles <u>because oxygen is adequate in their system and they do not need to respire anaerobically.</u> <em>Person X exercise regime must have been more rigorous than that of person Y.</em>
