TEAS Test 7 science quizlet

1. What is the muscular tube that transports sperm from the testes to the urethra called?

Correct answer: B

Rationale: The correct answer is the vas deferens. It is the muscular tube responsible for carrying sperm from the testes to the urethra. After sperm is produced in the testes, it moves to the epididymis for maturation and storage. The seminal vesicle contributes fluid to semen, but it is not the tube that transports sperm. Cowper's gland also adds fluid to semen but is not involved in transporting sperm. Therefore, the vas deferens is the accurate choice for the muscular tube that transports sperm.

2. What is correct about the hormones that stimulate male and female organs to produce male and female sex hormones?

Correct answer: C

Rationale: The correct answer is C. The same hormones stimulate both male and female organs to produce sex hormones. Hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by the pituitary gland and act on the ovaries in females and the testes in males to stimulate the production of sex hormones (estrogen and progesterone in females, testosterone in males). Therefore, the same hormones stimulate both male and female organs to produce sex hormones. Choices A, B, and D are incorrect because they do not accurately describe the relationship between hormones and the stimulation of male and female organs to produce sex hormones.

3. What is the hypodermis composed of?

Correct answer: B

Rationale: The correct answer is B: Adipose and areolar connective tissue. The hypodermis, also known as the subcutaneous layer, is primarily composed of adipose (fat) and areolar (loose) connective tissue. These tissues provide insulation, cushioning, and energy storage. Epithelial tissue (Choice A) is not a significant component of the hypodermis, as it is mainly found in the epidermis and lining of internal organs. Collagen fibers (Choice C) are more abundant in the dermis, providing strength and support. Dense connective tissue (Choice D) is also present in the dermis but is not a major component of the hypodermis.

4. In which direction do the particles of the medium move in a transverse wave?

Correct answer: A

Rationale: In a transverse wave, the particles of the medium move perpendicular to the direction of wave travel. This means that the particles move up and down or side to side as the wave passes through the medium. This motion creates crests and troughs in the wave, leading to the characteristic oscillation observed in transverse waves. Choice B is incorrect because in transverse waves, the particle movement is not parallel to the direction of wave travel. Choice C is incorrect as the particles do not move in a circular motion in a transverse wave. Choice D is incorrect as the particles do not move opposite to the direction of wave travel; they move perpendicular to it.

5. What is the rigid structure that provides shape and support to plant cells?

Correct answer: A

Rationale: The correct answer is the cell wall, as it is the rigid structure that provides shape and support to plant cells. The cell wall is located outside the plasma membrane and is primarily composed of cellulose, giving it its rigid nature. The plasma membrane (option B) is a semi-permeable membrane surrounding the cell that regulates the movement of substances in and out of the cell. The nucleus (option C) houses the cell's genetic material and controls cellular activities. Cytoplasm (option D) is the gel-like substance within the cell that surrounds organelles and where various cellular processes take place, but it does not provide the rigid structure and support that the cell wall does.
