Mometrix TEAS 7 science practice test Questions
Question 1 of 5
What is the relationship between mass and weight on Earth's surface?
Correct Answer: C
Rationale: The correct answer is C: Weight is greater than mass. Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that object. On Earth's surface, weight is greater than mass because gravity pulls objects towards the center of the Earth, resulting in a force that we perceive as weight. Choice A is incorrect because mass and weight are not equal; weight is a force, while mass is a measure of the amount of matter. Choice B is incorrect because mass is not greater than weight; weight is the force exerted due to gravity. Choice D is incorrect as mass and weight are related; weight is dependent on mass and the gravitational force acting on the object.
Question 2 of 5
Where are most of the body's immune cells located?
Correct Answer: A
Rationale: - The majority of the body's immune cells are located in the blood. Immune cells, such as white blood cells (leukocytes), circulate throughout the body via the bloodstream to detect and fight off infections and foreign invaders. - While immune cells are also present in other parts of the body like the lymph nodes, spleen, and bone marrow, the blood serves as a primary conduit for immune cells to travel to different tissues and organs to carry out their functions. - The brain (option B) is protected by the blood-brain barrier, which limits the entry of immune cells into the brain to prevent inflammation and damage. - The skin (option C) contains immune cells like Langerhans cells that help protect against pathogens, but the largest concentration of immune cells is found in the blood. - The large intestine (option D) also houses a significant amount of immune cells due to its role in interacting with the external environment through the gut-associated lymphoid tissue, but the primary location for most of the body's immune cells is the blood.
Question 3 of 5
Which property of a wave determines its energy?
Correct Answer: B
Rationale: The energy of a wave is determined by its amplitude, which is the measure of its maximum displacement from the equilibrium position. Waves with higher amplitudes carry more energy as energy is directly proportional to amplitude. Therefore, the correct answer is B) Amplitude. Choice A (Wavelength) does not determine the energy of a wave; it is related to the spatial length between wave crests. Choice C (Frequency) is not the property that determines a wave's energy; it refers to the number of complete oscillations a wave undergoes in a given time. Choice D (Velocity) is the speed at which a wave propagates through a medium and is not directly related to its energy.
Question 4 of 5
What type of energy does an object in motion possess?
Correct Answer: B
Rationale: The correct answer is B. Kinetic energy is the energy possessed by an object in motion. When an object is in motion, it has the ability to do work due to its motion, which is known as kinetic energy. Potential energy, choice A, refers to stored energy that has the potential to do work but is not related to motion. Thermal energy, choice C, is related to the temperature of an object, not its motion. Chemical energy, choice D, is energy stored in the bonds of chemical compounds and is not directly related to an object's motion.
Question 5 of 5
Which gland is responsible for producing the fluid that carries sperm in the male reproductive system?
Correct Answer: D
Rationale: The correct answer is D: Seminal vesicles. Seminal vesicles are responsible for producing a significant portion of the fluid that makes up semen, providing nutrients and protection for the sperm. While the testes produce sperm, the scrotum is the external sac that holds the testes, and the prostate gland also contributes to semen production but is not solely responsible for it.
