ATI TEAS Science Test Questions

Question 1 of 5

Where is the abdominopelvic cavity in relation to the thoracic cavity?

Correct Answer: D

Rationale: The abdominopelvic cavity is located inferior to the thoracic cavity. The thoracic cavity contains organs like the heart and lungs, while the abdominopelvic cavity includes the abdomen and pelvis regions. Therefore, the correct answer is D, as the abdominopelvic cavity is positioned below (inferior to) the thoracic cavity. Choice A (Dorsal) is incorrect as it refers to the backside of the body. Choice B (Ventral) is incorrect as it refers to the front side of the body. Choice C (Superior) is incorrect as it indicates a position above the thoracic cavity, which is not the case.

Question 2 of 5

Based on the results that were stated, what would be a logical reason for some of the plants dying with the salt solution?

Correct Answer: A

Rationale: The most logical reason for some of the plants dying with the salt solution could be that salt caused the plants to begin to dry up, leading to their death. Excessive salt can disrupt the osmotic balance within plants, causing dehydration and ultimately death. Salt can create a hypertonic environment, drawing water out of plant cells and causing wilting and damage. Therefore, it is reasonable to assume that the presence of salt could have dried out some of the plants and caused them to die. Choices B and C are incorrect as the scenario presented indicates that the salt had a negative impact on the plants, causing some to die. Choice D is also incorrect as there is a valid reason provided for the plants dying due to the salt solution.

Question 3 of 5

How does water affect the temperature of a living thing?

Correct Answer: B

Rationale: Water has a high specific heat capacity, which means it can absorb and release a large amount of heat energy without causing a significant change in temperature. This property allows water to help regulate the temperature of living things by buffering against sudden temperature changes in the environment. Overall, water helps to maintain a stable temperature within living organisms, which is crucial for their survival and physiological processes. Choices A, C, and D are incorrect because water's high specific heat capacity enables it to stabilize temperatures rather than increasing, decreasing, or having no effect on them.

Question 4 of 5

How is homeostasis defined?

Correct Answer: D

Rationale: Homeostasis is defined as the tendency of the body to maintain a stable internal environment despite external changes. This process involves regulating various physiological parameters such as body temperature, blood pressure, and glucose levels to ensure optimal functioning and health. Option A is incorrect as it specifically refers to body weight regulation, which is not the sole focus of homeostasis. Option B is incorrect as it describes maintaining a constant temperature in a room, rather than the internal environment of the body. Option C is incorrect as it only addresses the prevention of hunger pains through food ingestion, which is not the overarching concept of homeostasis.

Question 5 of 5

Which of the following functions is NOT performed by the integumentary system, the skin?

Correct Answer: D

Rationale: The integumentary system, which includes the skin, performs various functions like protecting internal tissues from injury, waterproofing the body, and helping regulate body temperature. The function of returning fluid to the blood vessels is primarily associated with the lymphatic system, not the integumentary system. The skin contributes to fluid balance by regulating sweating and preventing excessive water loss, but it does not directly return fluid to the blood vessels, making this the correct answer. Choices A, B, and C are functions directly related to the integumentary system and are essential for maintaining the body's overall health and well-being.
