A researcher is studying the response of bacteria in a certain chemical. In three experiments, the bacteria swim towards the chemical, and in one experiment the bacteria skin away from it. What would be the most appropriate next step for the researcher? A. report only the first three experiments B. report all the experiments, but refrain from making any conclusion C. repeat the experiment several more times and apply the statistical analysis to the data D. repeat the experiment, adding a new chemical to determine its effect on the bacteria.	C. By repeating the experiment, the researcher could determine whether the instance of the bacteria swimming away from the chemical was simply due to chance. - Observing the same results would allow the researchers to make conclusions with more certainty, and statistical analysis would help determine the significance of the data. - Researchers use report all data (A), and reaching a conclusion is a vital part of any experiment (B). Adding a new chemical would completely change the experiment, so it would not be helpful (D)).
How many different types of tissue are there in the human body? A. 4 B. 6 C. 8 D. 10	A. There are four different types of tissue in the human body: * Epithelial * Connective * muscle * Nerve - Epithelial tissue lies the internal and external surfaces of the body.

They can expand ad contract, like on the inner longing of the bladder. - Connective tissue provides the structure of the body as well as the links between various body parts. Tendon, ligaments, cartilage, and bone are all examples of connective tissue. - Muscle tissue is composed of tiny fibers, which contract o move the skeleton.
