Answer:
Option (B).
Explanation:
Evolution is the process of the change of the species characteristics with the passage of time. The species that can adapt better in the environment has high chance of survival.
Human evolution has explained well in the evolution and involves human development from the ancestral primates. The human evolution has occurred at the short time might occur due to some genetic changes or mutation. The evolution of the human chromosome 2 has occurred in relatively short period of time. This shows that human have specific objectively measurable properties.
Thus, the correct answer is option (B).
Properly identifying each species.
Accurately recording his findings.
Not interfering with ecosystem while studying the birds.
The CRISPR-Cas system is widely found in bacterial and archaeal genomes as a defense mechanism against invading viruses and plasmids [1–6]. The type II CRISPR-Cas system from Streptococcus pyogenes relies on only one protein, the nuclease Cas9, and two noncoding RNAs, crRNA and tracrRNA, to target DNA [7]
The answer is breathing. This is what I got from my homework paragraph. <span>In breathing, oxygen and carbon dioxide are exchanged with the external environment but there is not a gain of energy and a chemical reaction does not occur. </span>
