Which function of the skeletal system would be especially important if you were in a car accident?
- storage of minerals
- protection of internal organs
- facilitation of movement
- fat storage

Introduction:
The skeletal system functions to provide support and movement to the body. In addition, it also renders protection to the vital and delicate organs of the body.
Answer to Problem 1RQ
Option (b) is the correct answer. The function of the skeletal system that would be specially important in a car accident is protection of internal organs.
Explanation of Solution
Justification for correct answer:
Option (b) is protection of the internal organs. The skull is a hard casing made of bones that protects the brain. The rib cage protects the visceral organs like heart, lungs, stomach, liver and others. The vertebral column protects the spinal cord. Thus these bony stuctures function to protect the vital organs of our body. During an accident these bony cages act as shield to the internal organs and protect them from severe damage. Hence, option (b) is the correct choice.
Justification for incorrect options:
Option (a) is given as storage of minerals. This is a long term function of the bones of the skeletal system. It is not related to protection in emergency situations like a car accident. Hence, option (a) is incorrect.
Option (c) is given as facilitation of movement. Movement provided by the skeletal system helps in day-to-day activities. A car accident is a situation of trauma where movemnet of body parts gets restricted due to psychological impact. More than movement protection is important in this situation. Hence, option (c) is incorrect.
Option (d) is given as fat storage. Fat storage by skeletal system has no role in protection. The adipose fat deposits under the skin provide cushion to internal organs from mechanical shock. Hence, option (d) is incorrect.
During an emergency like car accident, the strong bony structures like the skull, rib cage and vertebral column protect vital internal organs from major injuries.

- You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forwardDesign a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forward
- 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.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.

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-haemoglobinarrow_forward

It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
