Ascientist told his student assistants that he had sorted groups of mice by their intelligence and asked the assistants to assess the groups’ maze-solving abilities. the scientist had not actually sorted the mice by intelligence. the students rated the “highest intelligence” group of mice as the best maze solvers and the “lowest intelligence” group as the worst maze solvers. what was the scientist trying to demonstrate by doing this experiment?
a. experimental subjects should never be put into groups.
b. mice should not be judged by their intelligence.
c. higher intelligence mice are better maze solvers.
d. people can introduce their own biases into an experiment.

As for this problem, the most probable and the most likely answer for this would be D. People can introduce their own biases into an experiment.

Experimental subjects can be put into groups if there is a need for such. This usually covers the control group and the experimental group to see the difference and to prove or disprove a hypothesis. Thus, this is a very popular and common way in conducting experiments with subjects. As for the mice, they aren't being judged since they are only rated through observation. Their intelligence isn't more likely to be always equated to better maze solvers. The last one, on the other hand, gives us that when scientists don't cover up most factors that might influence the experiment and most especially their biases, this might lead to a waste of the experiment and/or a biased result.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
