The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. A phylogenetic tree also learned as a cladogram, is a schematic diagram used to show the alleged evolutionary relationships between taxa. Diagrams of phylogenetic trees are based on cladistics, or phylogenetic systematics, hypotheses.
Organization of life, according to taxonomy, divides creatures into three domains:
The Eukarya domain are the most easy because they are large enough for their morphological features to be easily seen.

Answer:
The correct answer is:
Includes at least two groups, one of which does not receive the experimental treatment. (B)
Explanation:
A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.
<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
During chemical reactions, the chemical bonds between atoms are altered. ... Enzymes make chemical reactions take less time by decreasing the activation energy of the chemical reaction. The role of the enzyme-substrate complex is to provide the energy to break or form bonds in chemical bonds.
