"the best explanation for these modified rice plants being flood resistant is that
(1)the gene for flood resistance was inserted into plant cells, which grew into plants whose cells are expressing this gene
(2)they were produced by fertilization, using gametes from two flood-resistant bacterial cells
(3)there was a mutation in the bacterial dna after it was inserted into the plant that caused it to be flood resistant
(4)the researchers used selective breeding for the flood-resistance trait"

Researchers randomly divide participants into groups. each group takes a different amount of omega-3 fatty acid supplements daily for a month. one group receives a placebo. the researchers measure the impact on cholesterol levels in the blood. what is the purpose of random assignment in this experiment? a, to produce treatment groups with similar characteristics b, to ensure that all people with high cholesterol have an equal chance of being selected for the study c, to increase the accuracy of the research results and prevent skewness in the data
