TEAS Test 7 science quizlet

1. Tendonitis is an inflammation of which part of the body?

Correct answer: B

Rationale: Tendonitis specifically refers to the inflammation of tendons, which are the thick cords that connect muscles to bones. The correct answer is tendons. Choice A, muscles, are not affected in tendonitis, but rather in myositis, which is the inflammation of muscles. Ligaments (Choice C) connect bones to other bones, while cartilage (Choice D) is a smooth and flexible tissue that covers the ends of bones at a joint. Therefore, the correct term for inflammation of tendons is tendonitis.

2. Mesosomes are the internal extensions of which of the following?

Correct answer: B

Rationale: Mesosomes are the internal extensions of the cell membrane, not the capsule, cell wall, or chromatin body. They play a crucial role in cell division and are essential for various cellular processes such as respiration and cell wall formation. Mesosomes are not associated with the capsule (choice A), cell wall (choice C), or chromatin body (choice D), making these options incorrect.

3. What is the Golgi apparatus?

Correct answer: D

Rationale: The Golgi apparatus is an organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It consists of a series of flattened sacs called cisternae and plays a crucial role in processing proteins synthesized in the endoplasmic reticulum. Option A is incorrect because the network of tubules that transport proteins and lipids throughout the cell is typically associated with the endoplasmic reticulum. Option B is incorrect as the structure described is more characteristic of a vacuole, which stores water and nutrients. Option C is incorrect as protein synthesis primarily occurs in the ribosomes, not the Golgi apparatus.

4. What element is responsible for the red color of blood?

Correct answer: B

Rationale: The correct answer is B: Iron. Hemoglobin, the protein responsible for carrying oxygen in red blood cells, contains iron in its heme group, contributing to the blood's characteristic red color. Magnesium (choice A), copper (choice C), and zinc (choice D) are not responsible for the red color of blood. Magnesium is an essential mineral involved in various physiological processes, copper is a trace element important for enzyme function, and zinc is a micronutrient essential for multiple cellular functions but not related to the red color of blood.

5. What is the name of the muscle responsible for pumping blood throughout the body?

Correct answer: D

Rationale: The correct answer is D, Cardiac muscle. The cardiac muscle is specifically designed to pump blood throughout the body and is found in the heart. In contrast, the bicep, tricep, and deltoid are skeletal muscles responsible for joint movement, not for pumping blood. The bicep is responsible for elbow flexion, the tricep for elbow extension, and the deltoid for shoulder abduction.
