Answer the following statements true (T) or false (F)

Question

1. Researchers can readily extract DNA from one organism and merge that DNA into another organism, applying genetic engineering as a possible cure to cancer or muscular dystrophy and other diseases. The scientific method can test a hypothesis to determine if this approach is morally right or wrong.

2. In this experiment, if the scientists giving the placebo (low, medium, or high vaccine doses) did not know which dose they were administering, then this would be an example of a double-blind experiment.

3. A theory is an advanced hypothesis that has been proven to be true.

4.



These glucose and fructose molecules will bond to form a monosaccharide with the removal of water.

5. The property of water demonstrated by a water strider, as it remains on top of the water, is that water molecules are held together by ionic bonds.

Answer 1

1.FALSE
Biology graduate students and medical students are commonly required to take bioethics classes, because it is understood that scientific information and technology cannot effectively measure aesthetic value in arts, right or wrong values in morals, or acceptability of ethics. This limitation does not prevent scientists from measuring numbers of people who hold to specific values within a population.
2. TRUE
An investigator's awareness of medical doses can potentially influence test-subject responses because of verbal and nonverbal communication.
3. FALSE
Scientists don't use "educated guesses" and "opinions" for hypotheses. Hypotheses are potential outcomes or explanations that can be tested one study at a time for support. Theories are broadly supported by evidence from numerous studies, propose explanation for the phenomenon, and offer predictive power for as yet unknown observations.
4. FALSE
Formation of new covalent bonds between monomers results in larger, multiple unit molecules. Read section 2.5 for more information.
5. FALSE
Water's partial charges allow it to be cohesive, so that the surface tension among molecules can support this light insect.
