Summary Introduction
To review:
Whether Anolis gundlachi regulates its body temperature or not.
Introduction:
Paul E. Hertz of Barnard College studied the regulation of body temperature in a lizard’s body. Studies have revealed that they maintain thermal homeostasis by perching in the sun to warm their body and for cooling down their body temperature they rest in shade. Null hypothesis stated that the lizards do not regulate body temperature and perch at random.

The Siamese cat pictured is called a “seal point” because it has seal-colored (dark brown) extremities. Some Siamese cats show the same color pattern, but the dark areas are of a lighter color or even a different shade—for example, lilac point, red point, blue point. What results would you predict if the experiments described in the text (shaving the cat and then increasing or decreasing temperature) were conducted on cats with these color patterns?
You find an old data set from a hibernation study. Unfortunately, the only information is what is listed in the table below:
a) Based upon the data presented, what type of organism is this data set likely to have been based on? Describe it using the vocabulary that we learned in class.
b) What might the species be?
c) Graph the body temperature data provided in the table AND also graph what the body temperature data might look like for a small hibernating mammal. You do not have to include a full figure caption but do need to include a legend, if applicable.
The range of regulated body temperatures in mammals is about 36 to 40°C , while in birds it is slightly higher, 38 to 42°C, close to the limit compatible with life. Why do you imagine birds maintain higher body temperatures thanmammals? Do you think eagles and hummingbirds maintain the same body temperatures? Explain.

- 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.arrow_forwardDescribe the wood frog's adaptation which is the ability to freeze its body. Is this adaptation behavioral, chemical, or physical adaptation? How does this adaptation help the wood frog survive?arrow_forwardThe Mojave Desert of the western United States is characterized by a hot, dry climate. Scientists predict that temperatures in this region will increase by an average of 4.7° F over the next 30 years. Birds found here (like ground-dwelling roadrunners) are endotherms and have many adaptations to reduce the amount of heat absorbed into the body while active in the daytime. If temperatures increase in this area as predicted, how might the plumage (the feathers covering the body) of these roadrunners change under the influence of natural selection? 1:The plumage will likely become longer and increase heat absorption into the body. 2:The plumage will likely become darker and increase heat absorbed from the environment. 3:The plumaqe will likely become lighter and increase heat reflected away from the body. 4:The plumage will likely become thicker and increase the amount of heat trapped by the body.arrow_forward
- Mr. Fede runs an experiment to see if eating fatty foods raises cholesterol He uses two groups of rabbits, one that gets fed a high fat diet, and one that does not. The groups are not different in any other way. After several days, and upon comparing the cholesterol level of both groups, he finds that the high fat diet group has higher levels. He concludes that eating fatty foods is bad for people. Has Mr. Fede come to a good conclusion? Explain why or why not, includingarrow_forwardA researcher wants to investigate whether a daily corn-based diet supplemented with powdered milk would increase the daily weight gain of growing calves.

Which of the following regularities among animals might also be an example of such a “law”?A. As a group, birds have better color vision than mammals.B. Reptiles have a much lower specific metabolic rate than mammals.C. Predators tend to have very good binocular vision; prey animals tend to be able to see over a very wide angle.D. Jump height varies very little among animals. Nearly all animals, ranging in size from a flea to a horse, have a maximum vertical leap that is quite similar.arrow_forward
