Expert Solution & Answer
Answer to Problem 1MCQ
Correct answer:
The mouse uses the most “energy per gram of body weight”. Therefore, option c. is correct.
Explanation of Solution
Reason for the correct statement:
The amount of energy needed to regulate each gram of body weight is inversely proportional to the size of the animal. The mouse has lesser weight as compared to python, eagle, and horse. So, the mouse will have more “energy per gram of body weight”.
Option c. is given as “mouse”.
As, “the mouse has the least weight, the “energy per gram of body weight”, is highest in the mouse” is the right answer.
Hence, option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “horse”.
The horse weight is greater than that of the eagle and mouse. The “energy per gram of body weight” will be lesser of horse relative to that of eagle and mouse. So, it is a wrong answer.
Option b. is given as “eagle”.
The eagle weight is greater than that of the mouse. The “energy per gram of body weight” will be lesser of eagle relative to that of the mouse. So, it is a wrong answer.
Option d. is given as “python”.
The python weight is greatest in all the four animals “mouse”, “eagle”, “horse”, and “python”. The “energy per gram of body weight” will be least of the python. So, it is a wrong answer.
Hence, options a., b., and d. are incorrect.
Conclusion
The “energy per gram of body weight” is highest in the mouse because mouse weight is least among the four animals.

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.

The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.
