The answer choices are not provided, so I cannot select the correct one. However, I may provide you examples and guidance on how to choose the correct one.
As mentioned in the explanation, a scientific question must have a variable that is changed, the independent variable, and a variable on which the effect of the change is measured. This is the dependent variable. Examples of such questions include:
How will the amount of water given to a plant affect its rate of growth?
What will be the amount of sugar that can be dissolved in water at a given temperature?
At what temperature will a balloon filled with air pop?
All of these questions may be tested using experiments.
I think its A (hope i helped)
Answer:
The the above statements are true about out groups.
Explanation:
a. Out groups called as the more related organism that determine the evolution of the in group traits.
Plesiomorphy means the ancestral character that determines the phylogenetic evolution of an individual.For example, presence of spinal column is a plesiomorphic character of mammals that are present in fish, amphibia,reptiles, birds etc.
b. In groups are diverge from the out group but the out groups are used as a point to compare with the in groups as it is essential to determine the evolution of a trait in a phylogeny.
c. Autapomorphic traits contain distinctive characters that is unique and found in a particular taxa but not found in a any other out group taxa.
d.Out groups are less evolved as they contain ancestral features and during evolution they are replaced by advance characters that are presently in in group traits.Out group study is required to study the evolutionary relationship of the in group trait.
The reason is they are afraid of being picked on by a bigger crowd therefore increasing their chances to be bullied
