TEAS version 7 quizlet science Questions

Question 1 of 5

What is the muscular tube that connects the mouth to the stomach?

Correct Answer: B

Rationale: The correct answer is B: Esophagus. The esophagus is indeed the muscular tube that connects the mouth to the stomach. Food is transported down the esophagus via peristalsis, a series of muscle contractions. The pharynx is the area behind the mouth and nasal cavity, the trachea connects the larynx to the bronchi in the lungs, and the larynx is the voice box located in the throat. Therefore, choices A, C, and D are incorrect in the context of the question.

Question 2 of 5

What term describes the bouncing back of waves after striking a surface or boundary?

Correct Answer: C

Rationale: The correct answer is 'Reflection.' Reflection is the term used to describe the bouncing back of waves after striking a surface or boundary. Diffraction, on the other hand, refers to the bending of waves around obstacles. Refraction is the bending of waves as they pass from one medium to another. Interference involves the combination of two or more waves that results in a new wave pattern. Therefore, in this context, choices A, B, and D are incorrect as they do not specifically relate to the bouncing back of waves after striking a surface or boundary.

Question 3 of 5

What is the longest bone in the human body?

Correct Answer: C

Rationale: The femur is indeed the longest bone in the human body. It extends from the hip to the knee, providing crucial support for the body's weight and enabling various movements. The tibia and fibula are bones in the lower leg, while the humerus is located in the upper arm. Therefore, choices A, B, and D are incorrect in this context.

Question 4 of 5

Which macromolecule serves as the repository of genetic information in all living organisms?

Correct Answer: B

Rationale: - DNA is the macromolecule that serves as the repository of genetic information in all living organisms. It carries the genetic instructions necessary for the growth, development, functioning, and reproduction of organisms. - RNA (option A) is involved in various cellular processes, including protein synthesis, but DNA is the primary molecule responsible for storing genetic information. - Proteins (option C) are essential for various cellular functions but do not serve as the primary repository of genetic information. - Carbohydrates (option D) are important for energy storage and structural support but do not store genetic information.

Question 5 of 5

Which vitamin requires the lymphatic system for proper absorption from the intestine?

Correct Answer: C

Rationale: The correct answer is Vitamin D. Vitamin D requires the lymphatic system for proper absorption from the intestine. Unlike vitamins A, C, and B12, which are absorbed directly into the bloodstream, vitamin D is absorbed into the lymphatic system first before entering the bloodstream. Therefore, options A, B, and D are incorrect as they do not rely on the lymphatic system for absorption from the intestine.
