TEAS version 7 quizlet science Questions
Question 1 of 5
What is the SI unit of measurement for acceleration?
Correct Answer: D
Rationale: The SI unit of measurement for acceleration is meters per second squared (m/s�). Acceleration is defined as the rate of change of velocity over time. It is a vector quantity with dimensions of length per time squared. Meters per second squared (m/s�) represents the change in velocity (meters per second) over a specific time interval (seconds) squared. Choice A, meters per second (m/s), represents velocity, not acceleration. Choice B, Newton (N), is the unit of force. Choice C, Meters (m), represents only distance, not acceleration. Therefore, the correct unit for acceleration is meters per second squared (m/s�).
Question 2 of 5
What are the fundamental units of structure and function in all living organisms, including humans, termed?
Correct Answer: D
Rationale: Cells are the fundamental units of structure and function in all living organisms. They are the basic building blocks of life and carry out essential functions necessary for an organism to survive and function properly. Muscles, organs, and tissues are composed of cells, but cells are the smallest unit that can carry out all the functions of life. Muscles are made up of muscle tissue, which in turn is composed of muscle cells. Organs are structures made up of different types of tissues working together, and tissues are groups of cells with a similar structure and function. Therefore, while muscles, organs, and tissues are important components of living organisms, cells are the fundamental units that perform all the vital functions of life.
Question 3 of 5
Which type of muscle tissue contracts involuntarily and is found in organs like the heart and intestines?
Correct Answer: C
Rationale: Smooth muscle is the type of muscle tissue that contracts involuntarily and is found in organs like the heart and intestines. Skeletal muscle is responsible for voluntary movements, like those involved in skeletal system actions. Cardiac muscle is found in the heart and contracts involuntarily, but it is distinct from smooth muscle. The heart's muscle is specialized and forms the myocardium, which is not the same as the smooth muscle found in organs like the intestines. Therefore, the correct answer is C) Smooth muscle.
Question 4 of 5
Which vitamin requires the lymphatic system for proper absorption from the intestine?
Correct Answer: C
Rationale: The correct answer is Vitamin D. Vitamin D requires the lymphatic system for proper absorption from the intestine. Unlike vitamins A, C, and B12, which are absorbed directly into the bloodstream, vitamin D is absorbed into the lymphatic system first before entering the bloodstream. Therefore, options A, B, and D are incorrect as they do not rely on the lymphatic system for absorption from the intestine.
Question 5 of 5
Which of the following scenarios represents an example of static friction?
Correct Answer: C
Rationale: The correct answer is C. Static friction occurs when two surfaces are in contact but not moving relative to each other. Pushing a stationary object involves static friction as you apply a force to overcome the friction keeping the object stationary. Choices A, B, and D involve kinetic friction, which occurs when two surfaces are moving relative to each other. Option A involves moving the box across the floor, which is an example of kinetic friction. Option B involves the movement of a car around a curve, which also relates to kinetic friction due to the relative movement between the tires and the road. Option D describes braking a car to stop, where the moving car's wheels interact with the road, creating kinetic friction to slow down and stop the car.
