Chapter 1, Problem 1ITD
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.

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.
150 patients with Crohn’s disease are given an experimental treatment in which they all drink “cocktails” containing thousands of pinworm eggs. Within one week, 72% of the patients report a reduction in their abdominal pain.
Fill in the following table.
Is there a control treatment (and, if so, what is it)?
Is there any accounting for individual variation?
Is there repetition in the experiment?
What, if any, confounding variables are not addressed in the experiment?
Can we say with some confidence that ingesting pinworm eggs is an effective treatment for the symptoms of Crohn’s disease?

Note: Be sure to clearly identify which Punnett Square you are talking about in your answer (you may want to go back and label the Punnett Squares in your previous question (ex.

Okay, let's try to figure out how we would decide what the difference between the two populations of fish is - why one is cold-resistant (and produces an antifreeze protein), and the other is not cold-resistant (and does not produce the antifreeze protein). Which of the below results from some experiments you did would lead you to conclude that the difference between the two fish evolved by phenotypic plasticity?

After the eggs had hatched, tadpoles were raised in artificially constructed 2 L containers in a laboratory. All containers were filled with 1 L of filtered tap water, and the water was changed every other day. Thirteen tadpoles were placed in each container, and the tadpoles were exposed to a 12-hour light: 12-hour dark photoperiod. All tadpoles were fed thawed spinach daily. The researchers randomly placed the tadpoles into containers exposed to one of four treatments, with nine replicates of each treatment, as follows: Low UVBR (<6.0 kJ/m2), low temperature (15OC) Low UVBR (<6.0 kJ/m2), high temperature (26OC) High UVBR (>70.0 kJ/m2), low temperature (15OC) High UVBR (>70.0 kJ/m2), high temperature (26OC) The researchers recorded the number of tadpoles still alive out of the original 13 in a container (percent survival) at different time periods.
