Summary Introduction

To explain:

The observation why explorers of Antarctica must eat thousands more Calories per day than people exploring the tropics.

Concept introduction:

The mechanism through which an organism maintains its body temperature is called as thermoregulation. On the basis of regulation of the temperature, organisms are classified as endotherm, ectotherm, and heterotherm. The presence of fat or feathers or fur in an endotherm help in retaining the body heat in the endotherms, and the endotherms are capable of maintaining homeostasis on their own.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
