TEAS 7 science quizlet Questions

Question 1 of 5

In physics, what does the term 'net force' refer to?

Correct Answer: A

Rationale: In physics, the term 'net force' refers to the total force acting on an object, considering all individual forces acting on it. It is crucial in determining the object's motion and acceleration as it represents the overall force applied to the object. Choice B, 'Force due to gravity,' is incorrect as it refers to a specific force acting on an object due to gravity. Choice C, 'Force in motion,' is incorrect as it does not define the concept of net force. Choice D, 'Force of friction,' is incorrect as it specifically refers to the force opposing motion when two surfaces are in contact.

Question 2 of 5

What is the difference between heat and temperature?

Correct Answer: B

Rationale: Heat and temperature are distinct concepts. Heat is a form of energy that transfers from a higher temperature object to a lower temperature object, while temperature represents the average kinetic energy of particles in a substance. Heat is quantified in units like Joules or calories, whereas temperature is typically gauged in degrees Celsius or Fahrenheit. Therefore, choice B correctly distinguishes between heat and temperature, making it the correct answer. Choices A, C, and D are incorrect because they do not accurately define the difference between heat and temperature. Choice A erroneously suggests they are the same, choice C confuses the direction of heat and temperature flow, and choice D provides inaccurate units for measuring heat and temperature.

Question 3 of 5

What is the difference between exhalation (expiration) and inhalation (inspiration)?

Correct Answer: A

Rationale: Exhalation (expiration) involves active muscle contraction, specifically the diaphragm and intercostal muscles, to decrease the volume of the thoracic cavity and push air out of the lungs. In contrast, inhalation (inspiration) is a passive process where the diaphragm and external intercostal muscles contract to increase the thoracic cavity volume, allowing air to flow into the lungs. Choice B is incorrect as exhalation removes carbon dioxide-rich air and inhalation brings in oxygen-rich air. Choice C is incorrect because both exhalation and inhalation can occur through the nose or mouth. Choice D is inaccurate as inhalation humidifies and warms the air, while exhalation cools and dries it.

Question 4 of 5

What is the primary function of hematopoietic tissue?

Correct Answer: C

Rationale: The primary function of hematopoietic tissue is the production of blood cells. Hematopoietic tissue, primarily found in the bone marrow, is responsible for generating red blood cells, white blood cells, and platelets. These blood cells are vital for oxygen transport, immune response, and blood clotting. Choices A, B, and D are incorrect as they do not reflect the main function of hematopoietic tissue. Building and repairing bone is primarily carried out by osteoblasts and osteoclasts, supporting and connecting tissues is a role of connective tissues like tendons and ligaments, and contracting for movement is a function of muscle tissue.

Question 5 of 5

What is the term for a group of organisms that can interbreed and produce fertile offspring?

Correct Answer: D

Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring, which is a fundamental concept in biology. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. Genus (option A) refers to a taxonomic rank that includes one or more closely related species, not the ability to interbreed. Phylum (option B) and kingdom (option C) are higher taxonomic ranks that encompass a broader range of organisms, not specifically defined by interbreeding and fertile offspring production. Therefore, the correct answer is 'Species.'
