person wants to know if the Florida Cottonmouth and Northern Cottonmouth differ in toxicity (strength of their venom). Which would be the best experimental design to answer this question? Question 4 options: Two snakes - one of each species - each bite a mouse. The mouse that dies more quickly tells you which snake has more toxic venom. Venom from 60 snakes - 30 of each species - is injected into a mouse. The mouse that dies more quickly tells you which snake has more toxic venom. Venom from two snakes - one of each species - is injected into a mouse. The mouse that dies more quickly tells you which snake has more toxic venom. 60 snakes - 30 of each species - each bite a mouse. The group of mice with the most deaths tells you which snake has more toxic venom.

The schematic below shows a human body cannulated (tubes are inserted to the body's vasculature) at three heights, B, F, and H. Blood would rise to the same height in each tube, similar to a column of water cannulated at three heights. The tubes can also be filled with a saline solution with a similar density to blood so that this will be a safer experiment to perform. For a typical adult, h, is 1.5 m and hB is 1.85 m. Using the gauge pressure at heart height from the problem above, assume the density kg of whole blood is 1060 m³ and that the average arterial (heart) pressure of this individual has been measured to be 97 mmHg. Express your answer to four significant digits. B H hB ин Image from: M. M. Sternbeim and J. W. Kane, General Physics, 2nd edition (Wiley 1991). Hint: How would you model this problem? Blood vessels can be thought of as tubes containing columns of blood? Which equations would apply to find the blood pressure at different depths? (a) Calculate the gauge pressure…
You're doing an experiment to test whether students fed a new element, "brainium", will do better on tests. 50 students are fed 250 mg of brainium everyday for a week, and 50 students are fed 250 mg of a placebo (something that looks like brainium, but isn't) everyday for a week. After the week of treatment all students are given the same test. Which are controlled variables? Select all that apply. The test scores. The amount (250 mg). The # of students. The 50 students taking brainium. Time (one week). The 50 students taking the placebo.

Which of the following statements is true according to Peter Singer? The use of animals in experiments is never justifiable. The use of animals in experiments is justifiable if the animals do not go endure pain. The use of animals in experiments is justifiable if only one animal in one experiment will save thousands of human lives and the animal received a benefit from the experiment. The use of animals in experiments is justifiable in any circumstance since they are lesser beings. None of the above.

Drug A is being tested for its effectiveness in easing menopause symptoms. In designing an experiment to test Drug A, which of the following would be a valid approach? a. Participants can choose whether to be in the experimental or control group. b. The experimental group will contain only females and the control group will contain only males. c. Unlike the experimental group, the control group should include subjects whose age is above 52 years. d. The experimental group will receive Drug A and the control group will receive a placebo.
A well-designed experiment will contain both positive and negative controls. Which of the following is a false statement? Choose one from the following: (A) a positive control experiment is missing some of the components of the experiment and should give a negative result (B) a positive control experiment contains all of the components of an experiment and should give a positive result (C) a negative control experiment is missing the element being tested and should give a negative result (D) if there are multiple components of an experiment, there should be multiple negative controls (E) if a negative control experiment give positives results, it is likely that the experiment is contaminated
