Answer:
Random Assignment
Explanation:
Random Assignment
Is to randomly assign subjects to different treatment groups to reduce the chances of preexisting differences between the subjects having an impact (negative) on the experiment.
Answer:
Examples include rabbits, bacteria, salmon, plants such as weeds and grasses, etc. Many insects are r-selected. For example, ants can be considered r-selected. Plants such as dandelions are another good example of an r-selected species.

Answer: Option (A) is the correct answer.
Explanation:
A group in a periodic table is represented by a column. And, when we move down a group then there occurs an increase in atomic size or atomic radii of the elements.
This is because number of electrons add into new shells which leads to increase in atomic radii of the element.
Therefore, if we say that two elements in a group have similar atomic radii then it is false.
Whereas the two elements of a group might have a high melting point.
Also the statements, the two elements both are highly reactive in oxygen and the two elements both bonds with chlorine to form a salt in a 1 to one ratio can be true for elements of the same group.
Thus, we can conclude that the statement two elements both have similar atomic radii would not support the conclusion that two elements are in the same group.
