TEAS 7 science practice questions

1. What is the relationship between force and acceleration according to Newton's second law?

Correct answer: A

Rationale: According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is mathematically expressed as F = ma, where F represents force, m represents mass, and a represents acceleration. Therefore, an increase in force will result in a proportional increase in acceleration, supporting the statement that force is directly proportional to acceleration. Choice B is incorrect as it suggests an inverse relationship, which is not consistent with Newton's second law. Choice C is incorrect because force and acceleration are indeed related as per Newton's second law. Choice D is incorrect as force can cause acceleration or deceleration depending on the direction of the force relative to the motion of the object, but it does not exclusively cause deceleration.

2. Which of the following is an end product of cellular respiration?

Correct answer: B

Rationale: The correct answer is B: ATP energy. During cellular respiration, glucose is broken down to produce ATP, which is the primary energy currency of cells. While oxygen is required for cellular respiration to occur, it is not an end product but rather a reactant. Carbon dioxide and water are byproducts of cellular respiration, alongside ATP. Therefore, options A, C, and D are incorrect as they are not end products of cellular respiration.

3. Which of these organisms belongs to the kingdom Protista?

Correct answer: C

Rationale: A) Coral belongs to the kingdom Animalia, specifically in the phylum Cnidaria. B) Yeast belongs to the kingdom Fungi. C) Euglena is a unicellular organism that belongs to the kingdom Protista. It is a type of protist that has characteristics of both plants and animals. D) Mushroom belongs to the kingdom Fungi. Therefore, among the options provided, only Euglena belongs to the kingdom Protista.

4. DNA has both a 'sense' and 'antisense' strand. What is true about the antisense strand?

Correct answer: B

Rationale: The correct answer is B. The antisense strand runs 3' to 5', which is opposite to the direction of the sense strand. It serves as the template strand for transcription, where an RNA molecule is synthesized complementary to the antisense strand. Choice A is incorrect because the antisense strand runs in the opposite direction. Choice C is incorrect as the antisense strand is primarily involved in transcription, not replication. Choice D is incorrect as the direction of DNA storage is not determined by the antisense strand.

5. Bile, stored in the gallbladder, aids in the digestion of which nutrient?

Correct answer: C

Rationale: Bile, produced by the liver and stored in the gallbladder, aids in the digestion of fats. Bile emulsifies fats, breaking them down into smaller droplets to increase the efficiency of fat digestion by enzymes like lipase. This process enhances the absorption of fats in the small intestine, facilitating the body's utilization of essential fatty acids and fat-soluble vitamins. Carbohydrates are primarily broken down by enzymes like amylase, proteins by pepsin and other proteases, and vitamins have varying digestion and absorption processes, which do not involve bile. Therefore, the correct answer is fats as they are directly influenced by bile in the digestion process.
