1. What is the function of ribosomal RNA (rRNA)?

• A. Carries amino acids to the ribosomes
• B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
• C. Forms the structural framework of ribosomes
• D. Controls the rate of protein synthesis

Correct answer: C

Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.

2. Harry is a Unit Manager I the Medical Unit. He is not satisfied with the way things are going

• A. Call for a staff meeting and take this up in the agenda.
• B. Seek help from her manager.
• C. Develop a strategic action on how to deal with these concerns.
• D. Ignore the issues since these will be resolved naturally.

Correct answer: A

Rationale: Choosing option A, 'Call for a staff meeting and take this up in the agenda,' is the best course of action for Harry as a Unit Manager. By calling for a staff meeting, Harry can openly address his concerns with the team, gather input from team members, and work collaboratively to find solutions. This approach promotes transparency, communication, and teamwork, which are essential in resolving issues within a unit. Seeking help from his manager, as suggested in option B, may be necessary in some cases, but initiating a discussion with the staff first allows for a more inclusive problem-solving process. Developing a strategic action, as in option C, is important, but involving the team in this process through a staff meeting is crucial for buy-in and implementation. Ignoring the issues, as in option D, is never a productive approach as unresolved issues can escalate and impact team morale and performance. Therefore, option A is the most effective and proactive way for Harry to address hi

3. Which hormone stimulates the release of pancreatic enzymes and bile?

• A. Gastrin
• B. Insulin
• C. Cholecystokinin (CCK)
• D. Glucagon

Correct answer: C

Rationale: The correct answer is C: Cholecystokinin (CCK). Cholecystokinin is a hormone produced by the small intestine in response to the presence of food, especially fats and proteins. It stimulates the release of pancreatic enzymes from the pancreas and bile from the gallbladder to aid in digestion. Gastrin is a hormone that stimulates the release of gastric acid in the stomach. Insulin and glucagon are hormones involved in regulating blood sugar levels, not the release of pancreatic enzymes and bile. Therefore, CCK is the hormone responsible for stimulating the release of pancreatic enzymes and bile in the digestive process.

4. Insulin, a hormone responsible for regulating blood sugar levels, is produced by the:

• A. Parathyroid gland
• B. Pancreas
• C. Thymus gland
• D. Ovaries

Correct answer: B

Rationale: The correct answer is B: Pancreas. Insulin is a hormone that plays a crucial role in regulating blood sugar levels by allowing cells to take in glucose from the bloodstream. The pancreas is an organ located near the stomach that contains clusters of cells called islets of Langerhans, which are responsible for producing insulin. The parathyroid gland, option A, regulates calcium levels in the blood. The thymus gland, option C, is involved in the development of the immune system. The ovaries, option D, produce hormones like estrogen and progesterone but not insulin. Therefore, the pancreas is the correct gland responsible for producing insulin.

5. Which of the following is the main function of the liver?

• A. To produce bile, which helps digest fats
• B. To store energy in the form of glycogen
• C. To produce proteins that help to clot blood
• D. To detoxify harmful substances in the body

Correct answer: D

Rationale: Rationale: A) The liver does produce bile, which helps in the digestion of fats, but this is not its main function. Bile is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. B) While the liver does store energy in the form of glycogen, this is not its main function. Glycogen is a form of glucose storage that can be broken down into glucose when the body needs energy. C) The liver does produce proteins that help to clot blood, such as fibrinogen and prothrombin, but this is not its main function. These proteins are essential for the blood clotting process to prevent excessive bleeding. D) The main function of the liver is to detoxify harmful substances in the body. The liver processes and removes toxins, drugs, alcohol, and other harmful substances from the bloodstream, making them less harmful and

6. The outermost layer of your skin, responsible for waterproofing and providing a barrier against pathogens, is the:

• A. Stratum basale (Basal layer)
• B. Stratum corneum
• C. Stratum granulosum
• D. Stratum spinosum

Correct answer: B

Rationale: The correct answer is B: Stratum corneum. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells (corneocytes) that are continuously shed and replaced. This layer is responsible for waterproofing the skin and providing a barrier against pathogens, UV radiation, and other environmental factors. The stratum basale (A) is the deepest layer of the epidermis where new skin cells are produced. The stratum granulosum (C) is the layer of the epidermis where cells begin to flatten and keratinization begins. The stratum spinosum (D) is the layer above the stratum granulosum, where cells become interconnected by desmosomes. Therefore, the stratum corneum is specifically designed to fulfill the functions of waterproofing and protecting against pathogens.
