Science TEAS Practice Test Questions
Question 1 of 5
Which of the following is true regarding T cells?
Correct Answer: D
Rationale: The correct answer is D because T cells play a crucial role in the immune response by recognizing and attacking infected cells or pathogens. They are a type of white blood cell, making choice B valid. Choice C is accurate as T cells mature in the thymus during their development. Choice A is incorrect because T cells are present in all individuals, not just those with leukemia.
Question 2 of 5
Which of the following statements is NOT true of most metals?
Correct Answer: B
Rationale: The correct answer is B, "Most of them are gases at room temperature." Metals are typically solid at room temperature, not gases. This is because metals have high melting points due to their metallic bonding structure. Choice A is true as most metals are good conductors of heat due to the free movement of electrons. Choice C is also true, as metals are ductile and can be drawn into wires. Choice D is incorrect, as metals do not make up the majority of elements on the periodic table. Nonmetals, metalloids, and noble gases also exist.
Question 3 of 5
In order to be included in the formation of a scientific conclusion, evidence must be:
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.
Question 4 of 5
What type of bond is formed when electrons are transferred between atoms?
Correct Answer: D
Rationale: The correct answer is D: Ionic bond. In an ionic bond, electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that are attracted to each other. This transfer of electrons leads to the creation of a strong bond between the atoms. A: Transfer bond is not a recognized term in chemistry. B: Static bond is not a valid type of bond in chemistry. C: Covalent bond involves the sharing of electrons between atoms, not the transfer of electrons like in an ionic bond.
Question 5 of 5
A dietitian wants to convince a patient to lose weight. Which statement below best communicates a scientific argument that justifies the need for weight loss?
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.
