TEAS Test 7 science quizlet

1. What is the scientific term for a broken bone?

Correct answer: B

Rationale: The scientific term for a broken bone is a fracture. Osteoporosis is a condition characterized by weak and brittle bones, not a broken bone. A sprain involves an injury to a ligament, not a bone. Dislocation occurs when the ends of bones are forced out of their normal positions at a joint, which is different from a fracture.

2. The kidneys are bean-shaped organs that perform several vital functions. Which of the following is NOT a primary function of the kidneys?

Correct answer: C

Rationale: The correct answer is C. The kidneys do not produce red blood cells. This function is carried out by the bone marrow. The primary functions of the kidneys include filtering waste products from the blood, regulating blood pressure, and maintaining water balance in the body. Red blood cells are produced in the bone marrow, not in the kidneys. Choices A, B, and D are incorrect as they are primary functions of the kidneys, which involve filtering waste products, regulating blood pressure, and maintaining water balance in the body, respectively.

3. What is the muscular tube that transports sperm from the testes to the urethra called?

Correct answer: B

Rationale: The correct answer is the vas deferens. It is the muscular tube responsible for carrying sperm from the testes to the urethra. After sperm is produced in the testes, it moves to the epididymis for maturation and storage. The seminal vesicle contributes fluid to semen, but it is not the tube that transports sperm. Cowper's gland also adds fluid to semen but is not involved in transporting sperm. Therefore, the vas deferens is the accurate choice for the muscular tube that transports sperm.

4. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.

Correct answer: C

Rationale: Ionic bonds typically form between metals and non-metals, where one atom donates electrons (cation) and the other accepts electrons (anion). This results in the transfer of electrons. Metallic bonds, on the other hand, occur between metal atoms where electrons are shared among a sea of delocalized electrons, leading to the characteristic properties of metals like malleability and conductivity. Choice A is incorrect because ionic bonds involve electron transfer, not sharing. Choice B is incorrect as ionic bonds are strong, not weak, and are non-directional, while metallic bonds are strong and non-directional. Choice D is incorrect as ionic bonds do not form discrete molecules but rather a lattice structure, whereas metallic bonds form extended structures.

5. Which term describes the quantity of matter in an object and is measured in kilograms or grams?

Correct answer: B

Rationale: Mass is the quantity of matter in an object and is commonly measured in kilograms or grams. It is a fundamental property of matter and remains constant regardless of the object's location. Weight, in contrast, refers to the force of gravity acting on an object and is measured in newtons. Volume represents the amount of space an object occupies and is typically measured in cubic units like cubic meters or cubic centimeters. Density, on the other hand, is the mass of an object per unit volume, and its unit is, for example, kilograms per cubic meter. Therefore, the correct answer is 'Mass' as it specifically describes the quantity of matter in an object, regardless of the gravitational pull on it. 'Weight,' 'Volume,' and 'Density' do not directly represent the quantity of matter in an object but rather different properties related to it.
