Science TEAS Practice Test

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: D

Rationale: The correct answer is D because the ulna, fibula, and humerus are classified as long bones. Long bones are characterized by their elongated shape, with a shaft and two distinct ends. The ulna and humerus are long bones of the upper extremities, while the fibula is a long bone of the lower extremity. A, the sacrum, is a triangular bone at the base of the spine and is classified as a flat bone. B, the clavicle, is also a flat bone that connects the sternum to the scapula. C, the patella, is a sesamoid bone located in the knee joint and is not classified as a long bone. Therefore, the correct answer is D, as the ulna, fibula, and humerus are examples of long bones based on their structure and function.

Correct Answer: D

Rationale: The correct answer is D: Help red blood cells transport oxygen. Hemoglobin is a protein in red blood cells that binds to oxygen in the lungs and releases it in tissues. It does not transport oxygen itself, but it aids red blood cells in carrying oxygen. Choice A is incorrect because hemoglobin carries oxygen, not transports it. Choice B is incorrect because hemoglobin binds to oxygen, not to red blood cells. Choice C is incorrect because hemoglobin primarily transports oxygen, not carbon dioxide.

Correct Answer: B

Rationale: To be included in the formation of a scientific conclusion, evidence must be reproducible. This means that the findings can be repeated by other researchers to ensure the validity and reliability of the results. Reproducibility is essential in scientific research to confirm the accuracy of the findings and allow for independent verification. Quantitative evidence, while important in providing numerical data, is not always necessary for forming a scientific conclusion. Qualitative evidence, which describes qualities or characteristics, can also contribute to scientific conclusions. The choice "C: Obvious" is incorrect because scientific evidence may not always be obvious and often requires careful analysis and interpretation. Choice "D: All of the above" is incorrect because not all scientific evidence needs to be quantitative, and while reproducibility is crucial, it is not necessary for evidence to be obvious to be included in forming a scientific conclusion.
