TEAS Test 7 science
1. Which condition is commonly associated with frequent, painful urination?
- A. Diabetes
- B. Urinary tract infection (UTI)
- C. Kidney stones
- D. All of the above
Correct answer: D
Rationale: Frequent, painful urination can be indicative of various conditions. Diabetes may cause increased urination due to high blood sugar levels, UTIs can lead to pain and frequent urination, and kidney stones can also result in painful urination. Therefore, all of the options (A, B, and C) are correct in this scenario, making option D, 'All of the above,' the correct answer. Option D encompasses all the conditions commonly associated with frequent, painful urination, making it the most comprehensive and accurate choice.
2. Where is the scaphoid bone located in the body?
- A. Wrist
- B. Shoulder
- C. Spine
- D. Face
Correct answer: A
Rationale: The correct answer is A: Wrist. The scaphoid bone is one of the carpal bones located in the wrist. It is a small boat-shaped bone that is frequently involved in wrist injuries, such as falls onto an outstretched hand resulting in a scaphoid fracture. Choices B, C, and D are incorrect as the scaphoid bone is not located in the shoulder, spine, or face. Understanding the anatomical location of bones is crucial for diagnosing and treating injuries accurately.
3. How are mass and inertia related?
- A. Mass is a measure of inertia
- B. Mass has no relationship with inertia
- C. Inertia is a measure of weight
- D. Inertia increases with decreasing mass
Correct answer: A
Rationale: Mass is a measure of inertia. Inertia is the resistance of an object to changes in its state of motion, and mass quantifies this resistance. Objects with more mass have greater inertia, meaning they are more resistant to changes in their motion. Therefore, mass and inertia are directly related, with mass being a fundamental factor that determines the level of inertia an object possesses. Choice B is incorrect because mass and inertia are indeed related. Choice C is incorrect as inertia is not a measure of weight but rather a property related to an object's mass. Choice D is incorrect because inertia actually increases with increasing mass, not decreasing mass.
4. What is the fluid-filled, jelly-like substance within the cell that suspends the organelles called?
- A. Nucleus
- B. Cytoplasm
- C. Plasma membrane
- D. Golgi apparatus
Correct answer: B
Rationale: The correct answer is B, cytoplasm. Cytoplasm is the fluid-filled, jelly-like substance within the cell that suspends the organelles. The nucleus, not the correct answer, is the organelle that contains the cell's genetic material. The plasma membrane, another incorrect choice, is the outer boundary of the cell that regulates what enters and exits the cell. The Golgi apparatus, also an incorrect choice, is an organelle involved in processing and packaging proteins.
5. How does the stability of an atom's nucleus influence its radioactive decay?
- A. Stable nuclei never undergo radioactive decay.
- B. Unstable nuclei are more likely to decay through various processes.
- C. Decay releases energy, making stable nuclei more prone to it.
- D. The element's position on the periodic table determines its decay rate.
Correct answer: B
Rationale: Unstable nuclei are more likely to decay through various processes. The stability of an atom's nucleus is a crucial factor in determining whether it will undergo radioactive decay. Unstable nuclei have an excess of either protons or neutrons, causing an imbalance in the nucleus. To achieve a more stable configuration, these nuclei will undergo radioactive decay by emitting particles or energy. On the contrary, stable nuclei are less likely to undergo radioactive decay as they possess a balanced number of protons and neutrons. Choice A is incorrect because stable nuclei can still undergo radioactive decay, albeit less frequently. Choice C is incorrect as decay does not make stable nuclei more prone to it; rather, it stabilizes them. Choice D is incorrect because an element's decay rate is primarily determined by the nucleus's stability, not its position on the periodic table.
