Anatomy
1. Which type of white blood cell directly attacks and destroys pathogens like bacteria and viruses?
- A. Neutrophils
- B. Lymphocytes
- C. Monocytes
- D. Eosinophils
Correct answer: A
Rationale: The correct answer is A: Neutrophils. Neutrophils are a type of white blood cell that plays a crucial role in the innate immune response by directly attacking and destroying pathogens like bacteria and viruses. They are the most abundant type of white blood cell and are known for their rapid response to infections. Neutrophils work by engulfing and digesting pathogens through a process called phagocytosis. Lymphocytes (option B) are involved in adaptive immunity, producing antibodies and coordinating immune responses. Monocytes (option C) differentiate into macrophages and dendritic cells, playing a role in phagocytosis and antigen presentation. Eosinophils (option D) are primarily involved in combating parasitic infections and allergic reactions, not directly attacking bacteria and viruses.
2. The term "unconditional" in the context of UBI signifies that
- A. The amount received would be based on individual income and living expenses.
- B. Recipients would be required to meet certain criteria to qualify for the program.
- C. The money would be provided without any restrictions on how it is spent.
- D. The program would be temporary and subject to periodic review and renewal.
Correct answer: C
Rationale: The unconditional aspect of UBI refers to the lack of strings attached to its receipt, aligning with C.
3. Which hormone, produced by the pituitary gland, stimulates the production of milk in mammary glands during breastfeeding?
- A. Growth hormone (GH)
- B. Thyroid-stimulating hormone (TSH)
- C. Prolactin
- D. Follicle-stimulating hormone (FSH)
Correct answer: c
Rationale: The correct answer is C: Prolactin. Prolactin is the hormone produced by the pituitary gland that stimulates the production of milk in the mammary glands during breastfeeding. It plays a crucial role in lactation by promoting the growth and development of the mammary glands and initiating the production of milk. Growth hormone (GH) regulates growth and metabolism, not milk production. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland, not mammary glands. Follicle-stimulating hormone (FSH) is involved in reproductive processes, not milk production. Therefore, prolactin is the hormone directly responsible for stimulating milk production during breastfeeding.
4. Which type of energy is possessed by an object in motion?
- A. Potential energy
- B. Kinetic energy
- C. Thermal energy
- D. Chemical energy
Correct answer: b
Rationale: Kinetic energy is the energy possessed by an object in motion.
5. The intricate network of blood vessels responsible for transporting blood throughout the body is the:
- A. Lymphatic system
- B. Circulatory system
- C. Nervous system
- D. Respiratory system
Correct answer: B
Rationale: The correct answer is B: Circulatory system. The circulatory system is responsible for transporting blood, oxygen, nutrients, and other substances throughout the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The lymphatic system (A) is a separate system that helps to maintain fluid balance in the body and plays a role in the immune response. The nervous system (C) is responsible for transmitting signals between different parts of the body and the brain. The respiratory system (D) is responsible for the exchange of oxygen and carbon dioxide in the body through breathing. In this question, the circulatory system is specifically mentioned as the network of blood vessels responsible for transporting blood, making it the correct answer.
6. A syringe holds 3ml of liquid. How many syringes are needed to measure 15ml of liquid?
- A. 3
- B. 5
- C. 7
- D. 9
Correct answer: B
Rationale: Divide the total liquid volume (15ml) by the syringe capacity (3ml/syringe) to get 5 syringes.
