TEAS version 7 quizlet science

1. The control center of the cell, containing genetic information (DNA), is the:

Correct answer: C

Rationale: The correct answer is C, the nucleus. The nucleus is the control center of the cell and houses the genetic information in the form of DNA. The Golgi apparatus (choice A) is responsible for packaging and processing proteins, the ribosome (choice B) is involved in protein synthesis, and the endoplasmic reticulum (choice D) is involved in protein and lipid synthesis. Therefore, choices A, B, and D are not the correct answers as they do not house the genetic information or serve as the control center of the cell.

2. What lab equipment would most likely be used to precisely measure the volume of a liquid solution?

Correct answer: C

Rationale: A graduated cylinder is the most suitable lab equipment for precisely measuring the volume of a liquid solution. Graduated cylinders are designed with calibrated markings that allow for accurate volume measurements of liquids. The other choices are not appropriate for measuring liquid volume: Flasks are used for mixing or storing liquids, triple beam balances are used for measuring mass, and test tubes are typically used for holding small amounts of substances during experiments.

3. An object is initially at rest. Which of the following will definitely NOT cause it to move?

Correct answer: B

Rationale: The correct answer is B because if an object is initially at rest and no force is acting on it, it will remain at rest due to Newton's First Law of Motion. This law states that an object at rest will stay at rest unless acted upon by an external force. Choices A, C, and D all involve forces acting on the object, which would cause it to move according to Newton's laws of motion. Choice A, a constant force acting on the object, would cause it to move at a constant velocity. Choice C, a force that increases in magnitude over time, would accelerate the object. Choice D, a force that decreases in magnitude over time, would decelerate the object.

4. Which of the following lobes in the cerebral cortex is primarily responsible for processing and integrating sensory information received from the rest of the body?

Correct answer: C

Rationale: The parietal lobe is the correct answer because it is primarily responsible for processing and integrating sensory information received from the rest of the body, including touch, pressure, temperature, and pain. This lobe plays a crucial role in spatial awareness, perception, and attention to sensory stimuli. It helps individuals make sense of the world around them and is essential for various sensory processes. The frontal lobe (choice A) is more associated with functions like reasoning, planning, and problem-solving. The occipital lobe (choice B) is responsible for processing visual information. The temporal lobe (choice D) is involved in functions like memory, auditory processing, and language comprehension, but it is not the primary lobe responsible for processing and integrating sensory information from the body.

5. What is the largest lymphatic vessel in the body?

Correct answer: B

Rationale: The thoracic duct is the largest lymphatic vessel in the body, responsible for draining lymph from most parts of the body except for the right upper quadrant. The jugular vein, subclavian vein, and aorta are not part of the lymphatic system; they are blood vessels and do not serve as lymphatic vessels. Therefore, choices A, C, and D are incorrect as they are not associated with the lymphatic system's transport of lymph.
