Anatomy
1. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?
- A. Insulin
- B. Glucagon
- C. Estrogen
- D. Testosterone
Correct answer: A
Rationale: The correct answer is A: "Insulin." In type 1 diabetes, the main type of hormone deficiency is insulin. Insulin is produced by the pancreas and is crucial for regulating blood sugar levels by helping cells absorb glucose. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas, leading to a deficiency of insulin. This results in uncontrolled high blood sugar levels, which can have serious consequences if not managed properly. Glucagon, estrogen, and testosterone do not play a primary role in the hormone deficiency associated with type 1 diabetes.
2. What are the building blocks of proteins?
- A. Sugars
- B. Fatty acids
- C. Amino acids
- D. Nucleotides
Correct answer: C
Rationale: Rationale: Proteins are macromolecules made up of long chains of amino acids. Amino acids are the building blocks of proteins and are linked together through peptide bonds to form polypeptide chains, which then fold into specific three-dimensional structures to carry out various functions in the body. Sugars (A) are the building blocks of carbohydrates, fatty acids (B) are the building blocks of lipids, and nucleotides (D) are the building blocks of nucleic acids like DNA and RNA.
3. The main idea of the passage is that
- A. history solely teaches us about past events and has no relevance to the present.
- B. understanding history is crucial for comprehending current trends and shaping the future.
- C. historical knowledge is merely an interesting collection of facts with no practical value.
- D. learning from history requires solely focusing on its successes and ignoring its failures.
Correct answer: B
Rationale: Choice B accurately captures the passage's emphasis on history's multifaceted impact, providing insights into the present and potential visions for the future.
4. Which organ helps break down food by grinding it with your teeth?
- A. Stomach
- B. Esophagus
- C. Liver
- D. Mouth
Correct answer: D
Rationale: Rationale: The mouth is the organ that helps break down food by grinding it with your teeth. The process of chewing, also known as mastication, breaks down food into smaller pieces, making it easier to swallow and digest. The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed do not directly participate in the mechanical breakdown of food through chewing.
5. She notes that there is an increasing unrest of the staff due to fatigue brought about by
- A. Evaluate the overall result of the unrest
- B. Initiate a group interaction
- C. Develop a plan and implement it
- D. Identify external and internal forces.
Correct answer: C
Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.
6. What is the relationship between mass and inertia?
- A. Mass is a measure of inertia
- B. Mass has no relation to inertia
- C. Inertia is a measure of weight
- D. Inertia increases with decreasing mass
Correct answer: a
Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.
