ATI TEAS 7 Science Practice Test Questions

Question 1 of 5

What lab equipment would most likely be used to precisely measure the volume of a liquid solution?

Correct Answer: C

Rationale: A graduated cylinder is the most suitable lab equipment for precisely measuring the volume of a liquid solution. Graduated cylinders are designed with calibrated markings that allow for accurate volume measurements of liquids. The other choices are not appropriate for measuring liquid volume: Flasks are used for mixing or storing liquids, triple beam balances are used for measuring mass, and test tubes are typically used for holding small amounts of substances during experiments.

Question 2 of 5

Which of the following is NOT an element of the respiratory system?

Correct Answer: A

Rationale: The correct answer is A: Ribs. The ribs are part of the skeletal system, providing structure and protection to the thoracic cavity. The trachea, diaphragm, and alveoli are all essential components of the respiratory system. The trachea carries air to and from the lungs, the diaphragm aids in breathing by contracting and relaxing to change the volume of the thoracic cavity, and the alveoli are tiny air sacs where gas exchange occurs in the lungs. Therefore, ribs do not play a direct role in the respiratory process and are not considered a part of the respiratory system.

Question 3 of 5

Which of the following describes a responsibility of the integumentary system?

Correct Answer: B

Rationale: The correct responsibility of the integumentary system is to act as a barrier that blocks pathogens from entering the body, thus helping to prevent diseases and infections. This function serves as the first line of defense for the body against external threats. Choices A, C, and D are incorrect. Choice A is a function of the circulatory system, not the integumentary system. Choice C relates to the lymphatic system, not the integumentary system. Choice D involves the endocrine system, not the integumentary system.

Question 4 of 5

What function do ribosomes serve within the cell?

Correct Answer: B

Rationale: Ribosomes serve a crucial role in protein synthesis by translating mRNA into proteins. They are not involved in cell movement, protecting the cell from the environment, or aiding in digestion. Choice A is incorrect because ribosomes are not responsible for cell movement. Choice C is incorrect because ribosomes do not primarily protect the cell from its environment. Choice D is incorrect because ribosomes do not have enzymes that aid in digestion.

Question 5 of 5

In the suburban neighborhood of Northwoods, there has been a large population of deer, and residents have complained about them eating flowers and garden plants. What would be a logical explanation for the large increase in the deer population over the last two seasons?

Correct Answer: B

Rationale: The correct answer is B because a decrease in natural predators can lead to an increase in the deer population as there are fewer predators to control their numbers. This explanation aligns with the situation described in the question, where the deer population has increased, causing issues for residents. Choice A is incorrect because an increase in food sources would not directly explain the increase in the deer population. Choice C is incorrect as it introduces a new factor of migration which is not mentioned in the question. Choice D is incorrect as an increase in hunting licenses sold would likely have the opposite effect on the deer population.
