TEAS version 7 quizlet science Questions

Question 1 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 2 of 5

Which element shares the same group (family) on the periodic table with helium (He)?

Correct Answer: A

Rationale: Elements within the same group share similar electron configurations in their outermost shells, resulting in comparable chemical properties. Helium and Neon both belong to Group 18 (Noble Gases), explaining their similarities. Boron, Carbon, and Oxygen are not in the same group as Helium on the periodic table. Boron is in Group 13, Carbon is in Group 14, and Oxygen is in Group 16, which are different from Helium's Group 18.

Question 3 of 5

The outermost layer of your skin, responsible for waterproofing and providing a barrier against pathogens, is the:

Correct Answer: B

Rationale: The correct answer is B: Stratum corneum. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells that are constantly shed and replaced. It serves as a protective barrier against pathogens and helps to prevent water loss from the body. Choice A, Stratum basale, is the deepest layer of the epidermis where new skin cells are produced. Choice C, Stratum granulosum, is a layer of the epidermis where the cells begin to flatten and lose their nuclei. Choice D, Stratum spinosum, is a layer of the epidermis where cells become irregular in shape and have spiny projections.

Question 4 of 5

What is the law that states energy can neither be created nor destroyed?

Correct Answer: B

Rationale: The correct answer is the Law of Conservation of Energy. This law states that energy cannot be created or destroyed, only transformed from one form to another. The Law of Conservation of Matter (Choice A) is related to mass and the preservation of mass in a closed system, not energy. The Law of Universal Gravitation (Choice C) describes the force of attraction between objects with mass. The Law of Inertia (Choice D) states that an object will remain at rest or in uniform motion unless acted upon by an external force.

Question 5 of 5

When light interacts with a perfectly smooth surface, like a mirror, the dominant interaction is:

Correct Answer: D

Rationale: When light interacts with a perfectly smooth surface like a mirror, the dominant interaction is specular reflection. Specular reflection occurs when light rays are reflected off a smooth surface at the same angle as the incident angle, resulting in a clear and sharp reflection. Refraction, which involves the bending of light as it passes from one medium to another, is not the dominant interaction with a perfectly smooth surface. Diffraction, the bending of light waves around obstacles, is not the dominant interaction with smooth surfaces. Total internal reflection occurs when light is reflected back into a medium due to encountering a boundary at an angle greater than the critical angle, but it is not the dominant interaction on a perfectly smooth surface like a mirror.
