TEAS Test 7 science quizlet Questions

Question 1 of 5

Which hormone deficiency can lead to stunted growth and developmental delays in children?

Correct Answer: C

Rationale: The correct answer is C, Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in children. A deficiency in growth hormone can lead to stunted growth and developmental delays. Estrogen and testosterone are sex hormones that do not directly influence growth in the same way as growth hormone. Insulin primarily regulates blood sugar levels and is not the primary hormone responsible for growth and development in children.

Question 2 of 5

What is the study of the geographical distribution of organisms and the factors that influence it known as?

Correct Answer: C

Rationale: Biogeography is the scientific discipline that focuses on studying the geographical distribution of organisms and the factors that influence their patterns of distribution. This field investigates the reasons behind why species are located where they are, taking into account historical events, ecological interactions, and physical geography. Paleontology (option A) specifically deals with the study of fossils and the history of life on Earth, mainly focusing on extinct organisms. Taxonomy (option B) is the science that involves classifying and naming organisms based on their characteristics. Population genetics (option D) is concerned with the study of genetic variation and evolutionary processes within populations of organisms. Therefore, in the context of studying the distribution of organisms across space and time, biogeography is the most appropriate choice.

Question 3 of 5

What force keeps a car moving along a curved road?

Correct Answer: D

Rationale: The correct answer is D: Friction between the tires and the road. When a car travels along a curved road, the friction between the tires of the car and the road provides the necessary centripetal force required to keep the car moving in the curved path. This friction allows the tires to grip the road and prevent the car from sliding off the curve due to inertia or momentum. Choices A, B, and C are incorrect because gravitational force, normal force from the road, and air resistance do not play a significant role in keeping a car moving along a curved road. While these forces may have other effects on the car's motion, they are not the primary force responsible for maintaining the car's trajectory along a curve.

Question 4 of 5

What is the term for a solution that has a lower concentration of solute compared to another solution?

Correct Answer: B

Rationale: An unsaturated solution is the term used for a solution that has a lower concentration of solute compared to another solution. In an unsaturated solution, more solute could still be dissolved. The other options are incorrect. A saturated solution (A) contains the maximum amount of solute that can be dissolved and is in equilibrium with undissolved solute. A dilute solution (C) has a low concentration of solute, but it does not imply a comparison to another solution. A concentrated solution (D) has a high concentration of solute compared to the solvent, which is opposite to what is described in the question.

Question 5 of 5

Which muscles play a significant role in the process of forced exhalation by contracting to reduce the thoracic cavity volume?

Correct Answer: D

Rationale: The abdominal muscles play a significant role in forced exhalation by contracting to reduce the thoracic cavity volume. When these muscles contract, the pressure within the thoracic cavity increases, assisting in the expulsion of air from the lungs. This action helps to compress the abdomen and push the diaphragm upwards, further decreasing the volume of the thoracic cavity and aiding in the exhalation process. The diaphragm (Choice A) is mainly involved in inhalation by contracting and moving downward to increase thoracic cavity volume. External intercostal muscles (Choice B) and internal intercostal muscles (Choice C) are primarily involved in the process of inhalation by expanding the thoracic cavity during normal breathing, rather than forced exhalation.
