TEAS Test 7 science quizlet Questions

Question 1 of 5

Which blood vessels are responsible for carrying oxygenated blood away from the heart to the rest of the body?

Correct Answer: B

Rationale: Arteries are the blood vessels responsible for carrying oxygenated blood away from the heart to the rest of the body. Their thick, muscular walls allow them to withstand high pressure and efficiently transport blood to various tissues and organs throughout the body. Veins (choice A) carry deoxygenated blood back to the heart, capillaries (choice C) facilitate the exchange of nutrients and waste products between the blood and tissues, and venules (choice D) are small blood vessels that collect blood from the capillaries and gradually converge into veins.

Question 2 of 5

Which hormone deficiency can lead to stunted growth and developmental delays in children?

Correct Answer: C

Rationale: The correct answer is C, Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in children. A deficiency in growth hormone can lead to stunted growth and developmental delays. Estrogen and testosterone are sex hormones that do not directly influence growth in the same way as growth hormone. Insulin primarily regulates blood sugar levels and is not the primary hormone responsible for growth and development in children.

Question 3 of 5

Which layer of the skin is responsible for new skin cell production?

Correct Answer: B

Rationale: The correct answer is B, Stratum basale. The stratum basale, also known as the basal layer or stratum germinativum, is the deepest layer of the epidermis and is responsible for new skin cell production through cell division. It contains basal cells that continuously divide to produce new keratinocytes, which move up through the layers of the epidermis. Choice A, Stratum corneum, is the outermost layer of the epidermis consisting of dead cells filled with keratin. It serves a protective function but is not involved in new skin cell production. Choice C, Stratum granulosum, is a layer of the epidermis where keratinocytes undergo changes in their structure and composition. It is involved in the process of keratinization but not in new skin cell production. Choice D, Stratum spinosum, is a layer of the epidermis where cells become interconnected by desmosomes. While it plays a role in providing strength and support to the epidermis, it is not primarily responsible for new skin cell production.

Question 4 of 5

What happens to the gravitational potential energy of an object as it falls freely?

Correct Answer: A

Rationale: The correct answer is A: 'It decreases.' When an object falls freely, its height decreases, resulting in a decrease in gravitational potential energy. The potential energy is converted into kinetic energy as the object accelerates due to gravity. This conversion process continues until the object reaches the ground or its lowest point, where the gravitational potential energy is minimal or zero. Choice B is incorrect because gravitational potential energy decreases, not increases, during free fall. Choice C is incorrect as gravitational potential energy changes due to the change in height. Choice D is incorrect as the gravitational potential energy does not instantly become zero but decreases gradually as the object falls.

Question 5 of 5

What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?

Correct Answer: B

Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.
