ATI TEAS 7 science review Questions

Question 1 of 5

Which type of cartilage allows for smooth movement at joints and absorbs shock?

Correct Answer: B

Rationale: Fibrocartilage is the correct answer. It is found in areas requiring both support and resilience, such as the intervertebral discs and knee joints. Fibrocartilage contains collagen fibers for strength and proteoglycans for resilience, making it suitable for functions that involve smooth movement at joints and shock absorption. Hyaline cartilage, while providing structural support, is not primarily responsible for smooth movement and shock absorption. Elastic cartilage is more flexible and is found in locations like the ear and epiglottis, but it is not known for its shock-absorbing properties. Choosing 'None of the above' disregards the correct option of fibrocartilage, which is specifically designed for the functions described in the question.

Question 2 of 5

Bile, a digestive juice, is produced by which organ?

Correct Answer: B

Rationale: Bile is a digestive juice produced by the liver. It is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The stomach (Choice A) produces gastric juices, not bile. The pancreas (Choice C) produces digestive enzymes and bicarbonate but not bile. The small intestine (Choice D) is where bile is released to aid in digestion but is not the organ that produces bile.

Question 3 of 5

What is the purpose of the periosteum, the tough outer layer of bone?

Correct Answer: B

Rationale: The periosteum, the tough outer layer of bone, serves the purpose of providing protection to the bone and nourishing it through the blood vessels it contains. It acts as a protective layer for the bone structures. Choices A, C, and D are incorrect because the periosteum does not produce red blood cells (which is the function of bone marrow), form joint surfaces (which is typically the role of articular cartilage), or store minerals (which is primarily done by bone tissue itself and not the periosteum).

Question 4 of 5

How is the muscular system benefited by regular exercise?

Correct Answer: B

Rationale: Regular exercise is beneficial for the muscular system by improving muscle strength and endurance. Exercise helps to build and maintain muscle mass, increase muscle strength, and enhance muscle endurance. It does not decrease muscle mass, make muscles less flexible, or increase the risk of muscle tears when done properly. Therefore, the correct answer is improving muscle strength and endurance, as it aligns with the positive effects of regular exercise on the muscular system.

Question 5 of 5

What is the atomic number of an element?

Correct Answer: A

Rationale: The atomic number of an element is the number of protons in an atom's nucleus. This number is crucial as it determines the element's identity and its position on the periodic table. Option B is incorrect because the number of neutrons can vary in isotopes but is not the atomic number. Option C is incorrect as the number of electrons in an atom's valence shell can vary based on the element's charge, not defining the atomic number. Option D is also incorrect because the number of isotopes is not the atomic number of an element.
