1. Which of the following is responsible for transporting oxygen in the blood?

Correct answer: B

Rationale: Red blood cells are responsible for transporting oxygen in the blood. Hemoglobin, a protein found in red blood cells, binds to oxygen in the lungs and carries it to tissues throughout the body. White blood cells are involved in the immune system's defense mechanisms against infections, platelets help in blood clotting, and plasma is the liquid component of blood that carries various substances like nutrients, hormones, and waste products.

2. Alpha waves, characteristic of quiet wakefulness and relaxation, have a frequency range of:

Correct answer: C

Rationale: Alpha waves are neural oscillations in the frequency range of 8-13 Hz, which are typically associated with a state of quiet wakefulness and relaxation. Option C, 8-13 Hz, is the correct frequency range for alpha waves. Choices A, B, and D are incorrect as they do not fall within the specific frequency range characteristic of alpha waves.

3. Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?

Correct answer: C

Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. Therefore, it does not primarily consist of photosynthetic organisms with cell walls made of cellulose. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic, so they do not fit the description. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This accurately describes plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.

4. Which of the following is the body cavity that contains the urinary bladder, urethra, and ureters?

Correct answer: B

Rationale: The correct answer is B, the pelvic cavity. The pelvic cavity houses organs related to the urinary and reproductive systems. The urinary bladder, urethra, and ureters are located in the pelvic cavity, making it the correct choice. The thoracic cavity contains the heart and lungs, while the abdominal cavity houses organs like the stomach and intestines. The spinal cavity, on the other hand, protects the spinal cord. Therefore, options A, C, and D are incorrect as they do not house the specific organs mentioned in the question.

5. Which of the following glands produces growth hormone?

Correct answer: A

Rationale: The correct answer is A: Pituitary. The pituitary gland, also known as the master gland, produces growth hormone, which plays a crucial role in stimulating growth and cell reproduction. Choice B, the thyroid gland, primarily produces hormones that regulate metabolism, not growth hormone. Choice C, the adrenal glands, produce hormones like cortisol and adrenaline, but not growth hormone. Choice D, the pancreas, produces insulin and glucagon for regulating blood sugar levels, not growth hormone.
