Science TEAS Practice Test

Correct Answer: B

Rationale: The correct answer is B: Quantitative data is more accurate than qualitative data. This statement is false because the accuracy of data depends on the research question and the methodology used, not on whether it is qualitative or quantitative. Both types of data have their strengths and limitations. Quantitative data is numerical and lends itself to statistical analysis, but it can lack depth and context. Qualitative data, on the other hand, provides rich insights into perspectives and behavior but may be subjective. Therefore, it is essential to use both types of data in scientific research to gain a comprehensive understanding of a research problem.

Correct Answer: C

Rationale: The correct answer is C: The pancreas. The pancreas functions as both an endocrine and exocrine gland. It secretes digestive enzymes (exocrine function) into the small intestine and produces hormones such as insulin and glucagon (endocrine function). This dual role allows the pancreas to regulate both digestion and blood sugar levels. Incorrect Answers: A: The kidney - Functions mainly in filtration and regulation of fluid balance, not as an endocrine/exocrine gland. B: The spleen - Primarily involved in immune function and blood filtration, not as an endocrine/exocrine gland. D: The stomach - Secretes digestive enzymes, but does not have a significant endocrine function like the pancreas.

Correct Answer: C

Rationale: The correct answer is C: An inference. This is because the statement "someone must have forgotten to water it" is not a direct observation but a conclusion drawn based on the observed condition of the dead flower. In making this statement, the speaker is connecting the lack of water to the flower being dead, which requires logical reasoning. A: A classification - This choice does not apply as the statement does not categorize or group anything. B: An observation - While the initial part of the statement is an observation (the flower is dead), the second part goes beyond just stating what is observed to drawing a conclusion based on that observation. D: A collection - This choice does not make sense in this context as the statement does not involve gathering or assembling items.

Correct Answer: A

Rationale: The correct answer is A because it provides a logical and evidence-based explanation for the need for weight loss. Losing weight can lower blood pressure, increase energy levels, and promote overall health, which are all scientifically proven benefits. Choice B is irrelevant to the health benefits of weight loss. Choice C focuses on social perceptions rather than health benefits. Choice D oversimplifies the process of losing weight, which is not always easy and requires effort and commitment.
