TEAS Test 7 science Questions

Question 1 of 5

What is the primary function of coronary arteries?

Correct Answer: B

Rationale: The primary function of coronary arteries is to supply oxygenated blood to the heart muscle itself. The heart is a muscle that needs a constant supply of oxygen and nutrients to function properly. Coronary arteries branch off the aorta and specifically deliver oxygenated blood to the heart muscle, ensuring its proper function. Choice A is incorrect because coronary arteries do not deliver blood throughout the entire body but specifically to the heart. Choice C is incorrect as coronary arteries carry oxygenated blood away from the heart. Choice D is incorrect as the primary function of the coronary arteries is not to regulate blood pressure but rather to provide oxygenated blood to the heart muscle.

Question 2 of 5

What is the purpose of genetic counseling?

Correct Answer: C

Rationale: The purpose of genetic counseling is to provide information and support to individuals and families with genetic risks. Genetic counselors aim to explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support to help individuals make informed decisions regarding their genetic health. Choice A is incorrect because genetic counseling is not focused on treatment but rather on providing information and support. Choice B is incorrect as genetic counselors do not primarily diagnose genetic diseases in newborns but rather provide guidance and support based on existing diagnoses. Choice D is not the purpose of genetic counseling; genetic counselors do not collect DNA samples for research purposes but instead focus on assisting individuals and families in understanding and managing their genetic risks.

Question 3 of 5

Which element is a good conductor of electricity but is not a metal?

Correct Answer: C

Rationale: The correct answer is graphite. Graphite is a non-metal that is a good conductor of electricity due to its unique electronic structure. While metals are typically known for their conductivity, graphite is an exception to this rule. Copper (choice A), silver (choice B), and gold (choice D) are all metals and are known for their excellent conductivity. Therefore, they do not fit the criteria of the question, which specifically asks for an element that is a good conductor of electricity but is not a metal.

Question 4 of 5

Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?

Correct Answer: C

Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. Therefore, it does not primarily consist of photosynthetic organisms with cell walls made of cellulose. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic, so they do not fit the description. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This accurately describes plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.

Question 5 of 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.
