ATI TEAS 7 science review

1. Salts are formed by the reaction between:

Correct answer: B

Rationale: Salts are formed by the reaction between an acid and a base. This reaction is known as a neutralization reaction. In this reaction, the acid donates a proton (H+) to the base, resulting in the formation of water and a salt as the products. Choice A is incorrect because salts are not formed by the reaction of two acids. Choice C is incorrect as salts are not produced by the reaction of two bases. Choice D is incorrect because while salts can be formed from the reaction between a metal and a nonmetal, it is not the only way salts are produced.

2. Which type of cell division is responsible for growth and repair?

Correct answer: B

Rationale: Mitosis is the correct type of cell division responsible for growth and repair. During mitosis, a cell divides to produce two identical daughter cells, contributing to growth and tissue repair in multicellular organisms. Meiosis, on the other hand, is involved in the formation of gametes (sperm and egg cells) for sexual reproduction. Binary fission is a form of asexual reproduction in single-celled organisms, and osmosis is the movement of water molecules across a selectively permeable membrane. Therefore, choices A, C, and D are incorrect as they are not directly related to growth and repair in multicellular organisms.

3. Which of the following is an example of the location and function of cartilage in the body?

Correct answer: B

Rationale: Cartilage is a type of flexible connective tissue that acts as supportive pads providing cushioning at joints, like those found between the vertebrae of the spine. This specific function of cartilage helps in reducing friction and absorbing shock in these areas, contributing to joint flexibility and protection. Choices A, C, and D do not accurately describe the function and location of cartilage in the body. Option A incorrectly refers to dense connective tissue, which is different from cartilage. Option C describes tendons or ligaments, which are not cartilage. Option D refers to adipose tissue, which is a type of connective tissue that stores fat and provides insulation, but it is not cartilage.

4. The ureters are paired tubes that transport urine from the:

Correct answer: B

Rationale: The ureters are responsible for carrying urine from the kidneys to the bladder. Once urine is produced in the kidneys, it travels down the ureters to be stored in the bladder until it is eliminated from the body through the urethra. Therefore, the correct answer is B, 'Kidneys to the bladder.' Choices A, C, and D are incorrect as they do not accurately describe the function of the ureters in the urinary system. Choice A, 'Bladder to the urethra,' is incorrect because the ureters carry urine from the kidneys to the bladder, not from the bladder to the urethra. Choice C, 'Urethra to the kidneys,' is incorrect as the flow of urine is from the kidneys to the bladder via the ureters, not in the reverse direction. Choice D, 'Skin to the kidneys,' is unrelated to the urinary system; the ureters are not involved in transporting substances from the skin to the kidneys.

5. What is the role of the hypothalamus in the body?

Correct answer: B

Rationale: The correct answer is B: 'To regulate hormones.' The hypothalamus plays a crucial role in regulating hormones and maintaining homeostasis by controlling various functions such as hunger, thirst, body temperature, and sleep-wake cycles. While digestion, body temperature, and the immune system are important bodily functions, they are not primarily controlled by the hypothalamus. Therefore, choices A, C, and D are incorrect as they do not accurately represent the primary function of the hypothalamus.
