relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in
diving humans.

3. Shown below is the dental formula and digestive tract anatomy of three mammalian species
(A, B, and C). What kind of diet would you expect each species to have? Support your
answers with what you can infer from the dental formula and what you can see in the
diagram. Broadly speaking, what accounts for the differences?

- Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
