TEAS 7 science practice questions

1. What is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning?

Correct answer: C

Rationale: The cerebrum is the correct answer. It is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning. The brainstem (option A) is responsible for basic life functions such as breathing and heart rate, not higher cognitive functions. The cerebellum (option B) is responsible for coordination and balance, not higher cognitive functions. The thalamus (option D) acts as a relay station for sensory information, but it is not the largest part of the brain nor responsible for higher cognitive functions.

2. When an atom gains or loses electrons, it becomes a(n):

Correct answer: C

Rationale: When an atom gains or loses electrons, it becomes an ion. Gaining or losing electrons alters the atom's electron count and charge, creating a positively or negatively charged ion. A molecule is formed when two or more atoms are chemically bonded. An isotope is a variation of an element with a different number of neutrons. A compound consists of two or more different elements chemically bonded together.

3. Where is the pineal gland located in the body?

Correct answer: C

Rationale: The pineal gland is correctly located at the center of the brain, between the two hemispheres. It is a small endocrine gland often referred to as the 'third eye' due to its unique location. Choices A, B, and D are incorrect as the pineal gland is not situated below the larynx, above the kidney, or at the base of the brain.

4. Which of the following cations is found at the center of a heme?

Correct answer: C

Rationale: The correct answer is Iron (II) (Fe2+), which is the cation found at the center of a heme group. Heme contains an iron (II) ion that is coordinated within the porphyrin ring structure. This iron ion is crucial for the function of heme in binding and transporting oxygen in hemoglobin and myoglobin. Choice A (Cr (III)) is incorrect as chromium is not typically found at the center of a heme group. Choice B (Cu (II)) is incorrect as copper is not the cation typically present in heme. Choice D (Iron (III)) is also incorrect as heme predominantly contains iron (II) at its center, not iron (III).

5. Where does bile, a substance that aids in digesting fats, originate from?

Correct answer: C

Rationale: Bile is produced by the liver to aid in the digestion and absorption of fats. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to facilitate fat digestion. The stomach (option A) is responsible for the initial digestion of food through gastric juices but does not produce bile. The pancreas (option B) secretes digestive enzymes like lipase to further break down fats in the small intestine but does not produce bile. The gallbladder (option D) stores and concentrates bile but does not produce it.
