1. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?
- A. Pneumonia
- B. Emphysema
- C. Asthma
- D. Pleurisy
Correct answer: C
Rationale: The correct answer is C: "Asthma." Asthma is a chronic condition characterized by inflammation of the airways in the lungs, leading to symptoms like wheezing, shortness of breath, coughing, and chest tightness. Pneumonia (A) is an infection in the lungs caused by bacteria, viruses, or fungi. Emphysema (B) is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs. Pleurisy (D) is inflammation of the lining of the lungs and chest cavity. Therefore, asthma best fits the description provided in the question, making it the correct answer.
2. Which vitamin plays a vital role in muscle function and helps prevent muscle weakness and fatigue?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin D
- D. Vitamin E
Correct answer: B
Rationale: The correct answer is B: Vitamin B12. Vitamin B12 plays a crucial role in muscle function by aiding in the production of red blood cells, which carry oxygen to the muscles. This vitamin also helps maintain the health of nerves that control muscle movements. Deficiency in vitamin B12 can lead to muscle weakness and fatigue due to decreased oxygen delivery and impaired nerve function in the muscles. Vitamin A is important for vision and immune function, Vitamin D is crucial for bone health, and Vitamin E is an antioxidant that protects cells from damage, but they do not have the same direct impact on muscle function as Vitamin B12.
3. What is the process of converting ammonia, a byproduct of protein digestion, into a less toxic form?
- A. Deamination
- B. Transamination
- C. Decarboxylation
- D. Hydrolysis
Correct answer: A
Rationale: Rationale: Deamination is the process of removing an amino group from a molecule, such as converting ammonia (NH3) into a less toxic form like urea. Ammonia is a byproduct of protein digestion and needs to be converted into a less toxic form to be excreted from the body. Deamination is a key step in this process, which occurs mainly in the liver through the urea cycle. Transamination involves the transfer of an amino group from one molecule to another, not the removal of an amino group as in deamination. Decarboxylation is the removal of a carboxyl group from a molecule, and hydrolysis is the breakdown of a compound by adding water.
4. What characteristic unites all organisms in the kingdom Animalia?
- A. Multicellularity and heterotrophy
- B. Unicellular nature
- C. Photosynthesis
- D. Cell walls made of chitin
Correct answer: A
Rationale: Rationale: A) Multicellularity and heterotrophy: This is the correct answer because all organisms in the kingdom Animalia are multicellular (composed of multiple cells) and exhibit heterotrophy (obtain nutrients by consuming other organisms). B) Unicellular nature: This is incorrect because organisms in the kingdom Animalia are multicellular, not unicellular. C) Photosynthesis: This is incorrect because organisms in the kingdom Animalia do not perform photosynthesis; they are heterotrophs that obtain nutrients by consuming other organisms. D) Cell walls made of chitin: This is incorrect because organisms in the kingdom Animalia do not have cell walls made of chitin. Chitin is a structural polysaccharide found in the cell walls of fungi, not animals.
5. The athlete ran the race in record time. Which word is the present participle of the verb "run"?
- A. ran
- B. runs
- C. running
- D. runner
Correct answer: C
Rationale: The present participle form of a verb describes an ongoing action.
6. What property of matter refers to the amount of space occupied by an object?
- A. Mass
- B. Volume
- C. Weight
- D. Density
Correct answer: b
Rationale: Volume measures the amount of space occupied by an object.
