ATI TEAS Science Questions

1. In which type of cell would you expect to find a high concentration of lysosomes?

Correct answer: C

Rationale: The correct answer is C: Immune cells. Immune cells, such as macrophages, contain many lysosomes for breaking down pathogens. Lysosomes are organelles responsible for digestion and waste removal within the cell, and immune cells require a high concentration of lysosomes to aid in their defense mechanisms against pathogens. Choice A, Cardiac cells, is incorrect because lysosomes are not primarily abundant in cardiac cells. Choice B, Glandular cells, is incorrect as well since lysosomes are not specifically concentrated in glandular cells. Choice D, Neurons, is also incorrect because while lysosomes are present in neurons, they are not typically found in high concentrations compared to immune cells.

2. Which of the following is an example of a chemical change?

Correct answer: C

Rationale: Rusting iron is an example of a chemical change because it involves a chemical reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust). This reaction results in a change in the chemical composition of the iron, unlike dissolving sugar in water, boiling water, or crushing ice, which are physical changes. Dissolving sugar in water is a physical change as sugar molecules remain unchanged but disperse in water. Boiling water is also a physical change as water changes its state from liquid to gas due to heat. Crushing ice is a physical change as the solid ice changes its physical form without altering its chemical composition.

3. Where is the scapula in relation to the olecranon?

Correct answer: D

Rationale: The correct answer is D: 'Superior.' The scapula is located superior to the olecranon. In anatomical terms, 'superior' refers to a position above or higher than a reference point. 'Distal' is a term used to describe a position farther away from the point of attachment or origin. 'Lateral' refers to a position further away from the midline of the body. 'Ventral' refers to the front or anterior side of the body. In this case, the scapula being superior to the olecranon means it is positioned above the olecranon bone.

4. Which cavity contains all of the frontal cavities? Choose only ONE best answer.

Correct answer: D

Rationale: The correct answer is D: Ventral. The ventral cavity includes both the thoracic and abdominopelvic cavities. The frontal cavities are part of the ventral cavity, which is located towards the front of the body, while the dorsal cavity is towards the back. The dorsal cavity contains the cranial and vertebral cavities, not the frontal cavities. The thoracic cavity is part of the ventral cavity but does not encompass all the frontal cavities. The abdominopelvic cavity is also part of the ventral cavity, but it does not include all of the frontal cavities. Therefore, the ventral cavity is the correct choice as it encompasses all the frontal cavities.

5. Which of the following organs functions as both an endocrine and exocrine gland?

Correct answer: C

Rationale: The pancreas is the correct answer as it functions as both an endocrine and exocrine gland. The endocrine function involves secreting insulin and glucagon into the bloodstream to regulate blood sugar levels, while the exocrine function involves releasing digestive enzymes into the small intestine to aid in digestion. The kidney (Choice A) primarily functions in the excretory system by filtering blood and producing urine. The spleen (Choice B) is involved in the immune system and blood storage but does not have endocrine or exocrine functions. The stomach (Choice D) is mainly an organ of the digestive system, secreting gastric juices to aid in digestion, but it does not have a dual endocrine and exocrine function like the pancreas.
