ATI TEAS Science Questions
1. Where does sperm production occur?
- A. Prostate gland
- B. Seminal vesicles
- C. Scrotum
- D. Seminiferous tubules
Correct answer: D
Rationale: Sperm production occurs in the seminiferous tubules within the testes. These tubules are responsible for spermatogenesis, the process of sperm creation. The prostate gland and seminal vesicles contribute to seminal fluid production, while the scrotum houses the testes but does not produce sperm. Therefore, choices A, B, and C are incorrect as they are not sites for sperm production.
2. What is a characteristic property of acids?
- A. Bitter taste
- B. Sour taste
- C. Slippery feel
- D. Sweet taste
Correct answer: B
Rationale: The correct characteristic property of acids is a sour taste. Acids release hydrogen ions when dissolved in water, giving them a sour taste. Bitter taste is a property associated with bases, not acids. Slippery feel is a characteristic property of bases, due to their soap-like nature. Sweet taste does not accurately describe the characteristic property of acids, as they are known for their sour taste.
3. What type of tissue is bone composed of?
- A. Epithelial tissue
- B. Connective tissue
- C. Hard connective tissue
- D. Muscle tissue
Correct answer: B
Rationale: Bone is composed of connective tissue. Connective tissues are characterized by having cells scattered within an extracellular matrix. In the case of bone, the extracellular matrix is mineralized, giving bone its hardness and strength. Choice A, epithelial tissue, is not correct as bone is not primarily composed of epithelial cells. Choice C, hard connective tissue, is not a recognized category of tissue in the scientific classification; bone is classified under connective tissue. Choice D, muscle tissue, is incorrect as bone and muscle tissues are distinct types of tissues with different structures and functions.
4. Skeletal muscles are attached to bones by tough connective tissues called
- A. Ligaments
- B. Tendons
- C. Cartilage
- D. Fascia
Correct answer: B
Rationale: Skeletal muscles are attached to bones by tough connective tissues called tendons. Tendons are strong, fibrous cords that connect muscles to bones, allowing for movement and stability in the body. Ligaments (option A) connect bones to other bones, not muscles to bones. Cartilage (option C) is firm and flexible connective tissue found in various parts of the body, but it does not attach muscles to bones. Fascia (option D) is a connective tissue that surrounds muscles, providing support and protection, but it does not directly attach muscles to bones.
5. Testosterone is a crucial hormone in the male reproductive system. What is its primary function?
- A. Egg production
- B. Sperm production and development
- C. Regulation of the menstrual cycle
- D. Milk production
Correct answer: B
Rationale: Testosterone is a hormone primarily produced in the testes of males and is responsible for the development of male reproductive tissues, including the testes and prostate. Its primary function is the production and maturation of sperm cells, as well as the development of secondary sexual characteristics in males. Choice A, 'Egg production,' is incorrect as testosterone is not involved in the production of eggs. Choice C, 'Regulation of the menstrual cycle,' is incorrect because testosterone is not responsible for regulating the menstrual cycle, which is primarily governed by female hormones. Choice D, 'Milk production,' is incorrect as testosterone does not play a role in milk production, which is associated with other hormones like prolactin in females.
