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 endocrine system communicates through chemical messengers called:

Correct answer: B

Rationale: The correct answer is B: Hormones. The endocrine system communicates through hormones, which are chemical messengers produced by glands and released into the bloodstream to target specific cells or organs in the body. Enzymes are biological molecules that catalyze biochemical reactions, antibodies are part of the immune system, and neurons are cells that transmit nerve impulses. In this context, enzymes, antibodies, and neurons do not play roles in the endocrine system's communication process, making them incorrect choices.

3. Where does bile, a substance that aids in digesting fats, originate from?

Correct answer: C

Rationale: Bile is produced by the liver to aid in the digestion and absorption of fats. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to facilitate fat digestion. The stomach (option A) is responsible for the initial digestion of food through gastric juices but does not produce bile. The pancreas (option B) secretes digestive enzymes like lipase to further break down fats in the small intestine but does not produce bile. The gallbladder (option D) stores and concentrates bile but does not produce it.

4. Which of the following statements is true about the dependent variable?

Correct answer: C

Rationale: The correct answer is C. The dependent variable is the factor that is being measured or observed in an experiment. It is the outcome that is affected by changes in the independent variable. In graphical representations, the dependent variable is usually plotted on the y-axis, not the x-axis. Choice A is incorrect because a factor that remains constant is referred to as a constant, not a dependent variable. Choice B is incorrect as the independent variable's data is typically plotted on the x-axis. Choice D is incorrect because the dependent variable's data is usually plotted on the y-axis. Therefore, choice C accurately describes the dependent variable.

5. Which hormone, produced by the pancreas, is involved in the regulation of blood sugar levels by inhibiting the release of insulin and promoting the release of glucose into the bloodstream?

Correct answer: D

Rationale: The correct answer is D, Somatostatin. Somatostatin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels by inhibiting the release of insulin and promoting the release of glucose into the bloodstream. It acts as a counterbalance to insulin, preventing excess insulin secretion and ensuring the availability of glucose when needed. Therefore, somatostatin helps maintain blood sugar balance in the body. Choices A, B, and C are incorrect. Insulin is responsible for lowering blood sugar levels, while glucagon and cortisol have roles that differ from the functions described in the question.
