1. Which hormone is crucial for stimulating sperm production in males?
- A. Estrogen
- B. Progesterone
- C. Testosterone
- D. Insulin
Correct answer: C
Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone and is crucial for stimulating sperm production in males through the process of spermatogenesis. It is produced in the testes and plays a key role in the development and maintenance of male reproductive tissues, including the testes and prostate. Estrogen and progesterone are primarily female sex hormones, while insulin regulates blood sugar levels and metabolism. Therefore, testosterone is the hormone specifically responsible for stimulating sperm production in males.
2. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."
- A. "My biggest fear"
- B. "that I wouldn't live life to the fullest"
- C. "life"
- D. "the fullest"
Correct answer: B
Rationale: Option B functions as the object of the verb "is," making it a noun clause.
3. A children's toy consists of a half cylinder (diameter 10cm, height 8cm) attached to a cube with side lengths of 5cm. What is the total volume of the toy?
- A. 125 cu cm
- B. 200 cu cm
- C. 275 cu cm
- D. 350 cu cm
Correct answer: C
Rationale: Calculate the volume of the half cylinder and the cube separately, then add them up.
4. The kidneys are bean-shaped organs responsible for filtering waste products from the blood. What is the main nitrogenous waste product the kidneys eliminate?
- A. Carbon dioxide
- B. Ammonia
- C. Urea
- D. Glucose
Correct answer: C
Rationale: The correct answer is C: Urea. The kidneys filter waste products from the blood to maintain a proper balance of electrolytes and remove toxins. Urea is the main nitrogenous waste product formed from the breakdown of proteins in the liver. It is then excreted by the kidneys through urine. Carbon dioxide is a waste product of cellular respiration and is eliminated primarily through the lungs. Ammonia is a toxic compound that is converted to urea in the liver before being excreted by the kidneys. Glucose is a sugar that is normally reabsorbed by the kidneys and not excreted as waste.
5. The doctor carefully examined the patient. Which word is the comparative form of the adjective "careful"?
- A. careful
- B. carelessly
- C. more careful
- D. most careful
Correct answer: C
Rationale: The comparative form of an adjective compares two things.
6. Which of the following is NOT a type of vaccine?
- A. Live attenuated vaccine
- B. Toxoid vaccine
- C. Conjugate vaccine
- D. Antibiotic
Correct answer: D
Rationale: Rationale: A) Live attenuated vaccine: This type of vaccine contains a weakened form of the virus or bacteria that causes the disease. When administered, it stimulates an immune response without causing the disease itself. B) Toxoid vaccine: Toxoid vaccines are made from toxins produced by bacteria that have been inactivated. They stimulate the immune system to produce antibodies against the toxin, providing immunity against the disease. C) Conjugate vaccine: Conjugate vaccines are made by combining a weak antigen with a strong antigen to enhance the immune response. They are commonly used to protect against bacterial infections. D) Antibiotic: Antibiotics are medications used to treat bacterial infections by killing or inhibiting the growth of bacteria. They are not a type of vaccine but rather a class of antimicrobial drugs. Therefore, the correct answer is D) Antibiotic, as it is not a type of vaccine.
