TEAS Test 7 science quizlet Questions

Question 1 of 5

What is the tough, fibrous connective tissue that attaches muscle to bone?

Correct Answer: C

Rationale: Tendons are the correct answer as they are the tough, fibrous connective tissues that attach muscle to bone. They play a crucial role in transmitting the forces generated by muscle contraction to the bones, facilitating movement. Fascia surrounds muscles and provides support, perimysium is the connective tissue sheath around muscle fibers, and ligaments connect bone to bone, stabilizing joints, which makes them distinct from tendons.

Question 2 of 5

Which property of a substance refers to its ability to be stretched into thin wires?

Correct Answer: C

Rationale: Ductility is the property of a substance that allows it to be stretched into thin wires without breaking. It is a crucial property for materials used in wire production. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be stretched into wires. Viscosity is the measure of a fluid's resistance to flow, not its ability to be stretched. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not stretched into wires.

Question 3 of 5

How can a concave mirror be used?

Correct Answer: A

Rationale: A concave mirror can be used to focus light to a single point. This property is known as converging light rays to a focal point. When light rays parallel to the principal axis strike a concave mirror, they converge at a specific point called the focal point. This ability to focus light makes concave mirrors useful in applications such as reflecting telescopes and shaving mirrors. Choice B is incorrect because concave mirrors can create both real and virtual images, depending on the object's position relative to the mirror. Choice C is incorrect as concave mirrors can magnify, reduce, or maintain the size of objects, depending on the object's position and the distance from the mirror. Choice D is incorrect as concave mirrors do not scatter light but instead have the ability to reflect and focus light to produce clear images.

Question 4 of 5

What happens to the gravitational potential energy of an object as it falls freely?

Correct Answer: A

Rationale: The correct answer is A: 'It decreases.' When an object falls freely, its height decreases, resulting in a decrease in gravitational potential energy. The potential energy is converted into kinetic energy as the object accelerates due to gravity. This conversion process continues until the object reaches the ground or its lowest point, where the gravitational potential energy is minimal or zero. Choice B is incorrect because gravitational potential energy decreases, not increases, during free fall. Choice C is incorrect as gravitational potential energy changes due to the change in height. Choice D is incorrect as the gravitational potential energy does not instantly become zero but decreases gradually as the object falls.

Question 5 of 5

Why do Neon (Ne) and Helium (He) belong to Group 18 (Noble Gases)?

Correct Answer: A

Rationale: Neon (Ne) and Helium (He) belong to Group 18 (Noble Gases) because they have complete and stable outer electron shells. The stability of these outer electron shells is due to the balance of attractive forces between the positively charged protons in the nucleus and the negatively charged electrons in the outer shell. This balance is maintained by the electromagnetic force, which is responsible for holding atoms together and determining their chemical properties. Gravity (Choice B) is a force of attraction between objects with mass and is not responsible for the stability of electron shells. The strong nuclear force (Choice C) and weak nuclear force (Choice D) are forces that act within the nucleus of an atom and are not directly related to the stability of outer electron shells in determining an element's group in the periodic table.
