Question
Chapter 25, Problem 22TYK
Summary Introduction
To hypothesize: Why dolphin flippers do not freeze and also to describe an experiment to test the proposed hypothesis. In addition to this, also determine the result that would be expected if the hypothesis is correct.
Concept introduction:
Dolphins can maintain a constant internal body temperature. Therefore, they are endotherms. They have various mechanisms to maintain a constant body temperature, such as the presence of blubber, a thick layer of fat in their skin and counter current heat exchange mechanism.

A biology student is investigating the claim that the temperature can be predicted by counting cricket chirps. He has collected data and comes up with the linear model T=39.2+0.233r, where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. Interpret the slope of the equation.
The model predicts a decrease of 0.233 degrees for each increase of 1 chirp per minute.
The model predicts a decrease of 39.2 degrees for each increase of 1 chirp per minute.
The model predicts an increase of 39.2 degrees for each increase of 1 chirp per minute.
The model predicts an increase of 0.233 degrees for each increase of 1 chirp per minute.
Rock pocket mice can either have a dark black coloration or light coloration. You observe that most of the pocket mice that live on dark rocks are dark black in coloration, and that the pocket mice that are light in color live on light-colored sand. You hypothesize that the coloration differences serve as camouflage protecting the mice against predators.
Design an experiment to test your hypothesis. Describe this experiment in 3-4 sentences. In this description, make sure you indicate the following: dependent variable, independent variable, and your prediction.
Consider an experiment in which subjects are given a pill to test its effectiveness in reducing the duration of a cold. Which of the following is the best way to treat the control group? (a) Give the control group two pills instead of one. (b) Do nothing with the control group. (c) Give the control group a pill that looks like the test pill but does nothing. (d) Let the control group choose whether or not to take any pills. (e) Expose the control group to the cold virus.

An adult chimpanzee (Sarah) was shown 30-second videotapes of a human actor struggling with one of several problems (for example, not able to reach bananas hanging from the ceiling, a record player not playing). Then Sarah was shown two photographs, one that depicted a solution to the problem (like stepping onto a box, plugging in the record player) and one that did not. She was then instructed to pick one of the photos and place it under the television monitor. (Sarah had been raised in captivity since age one and had extensive prior exposure to photographs and television.) The order in which the scenes were presented to Sarah was randomized, as was the left/right position of the photos presented to her. Sarah was shown eight different scenarios. For each scenario, researchers recorded whether Sarah selected the…arrow_forward

Their expedition is happening in winter, and the group set out each carrying a pack of supplies including tents, sleeping gear, and food for either 3 well-fed days or up to 8 days with rationing (approximately 30kg each). The treasure hunters travel on foot to get to the castle through lands where there are predators such as wolves and bears. They have two options in terms of speed of travel: slow (7 days to castle), and fast (4 days to castle). 1) As an advisor to the group, which speed would you say they should travel? Note – neither speed is wrong however your answer must justify your choice in terms of physiology. Once the group get to the…arrow_forward
