Chapter 26, Problem 1MCQ
Summary Introduction

Introduction:

Skeleton is a hard structure that protects the internal organs of a living organism. A system, composing bones, muscles, and other tissues that help in the movement and locomotion in an individual, is called a skeletal system.

Answer to Problem 1MCQ

Correct answer:

Exoskeleton and endoskeleton differ from each other in protecting the animal body from outside as well as its ability to grow with an organism. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

Option d. is given as “both a and b are correct.”

Skeleton system is the culmination of joints and bones present in the body of an individual. The skeleton system secures the internal body organs of different organisms. For example, the skull is part of the skeletal system that helps in the protection of the brain. The exoskeleton protects the individual from different kinds of environmental stress and develops with the growth of the organism.

Reason for incorrect answer:

Option a. is given as, “their ability to protect an animal from the outside.”

The exoskeleton also shows the ability to grow with the organism. Hence, option a. is incorrect.

Option b. is given as, “their ability to grow along with organism.”

The exoskeleton protects the internal organs of the body as well. Hence, option b. is incorrect.

Option c. is given as, “their function as a framework for muscle attachment.”

The concept of muscle attachment is related to the endoskeleton system. Hence, option c. is incorrect.

Hence, the options a., b., and c. are incorrect.

Conclusion

Exoskeleton and endoskeleton differ from each other in protecting the animal body from the outside environment as well as its ability to grow along with an organism. Thus, the correct answer is option d.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. 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.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
