TEAS 7 science practice questions

1. What is the term for a group of organisms with the same genetic makeup?

Correct answer: B

Rationale: In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. A population (option A) refers to a group of individuals of the same species living in the same area. Genotype (option C) refers to the genetic makeup of an individual organism. Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, the most appropriate choice for the question is 'Clone,' as it specifically refers to organisms with the same genetic makeup.

2. Which of the following is a characteristic of alkenes?

Correct answer: A

Rationale: Alkenes are hydrocarbons that contain at least one carbon-carbon double bond. This double bond is a key characteristic that distinguishes alkenes from other types of hydrocarbons. Option A correctly identifies this defining feature of alkenes, making it the correct answer. Choices B, C, and D are incorrect. Choice B is incorrect because alkenes are unsaturated hydrocarbons due to the presence of double bonds. Choice C is incorrect as alkenes do not contain only single bonds; they have at least one double bond. Choice D is incorrect because alkenes are not derivatives of ammonia; they are a distinct class of organic compounds with carbon-carbon double bonds.

3. 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.

4. Identify the INCORRECT function of the liver.

Correct answer: D

Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

5. 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.
