Science TEAS Practice Test Questions
Question 1 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 2 of 5
Which of the following layers of the skin does not contain blood vessels?
Correct Answer: C
Rationale: The correct answer is C: Epidermis. The epidermis is the outermost layer of the skin and is avascular, meaning it does not contain blood vessels. This is important for maintaining its protective function and preventing blood loss in case of injury. The hypodermis (A) contains blood vessels that supply the skin with nutrients and regulate temperature. The dermis (B) is rich in blood vessels, providing nourishment to the skin and regulating temperature. Option D (Hyperdermis) is not a recognized layer of the skin, making it an incorrect choice.
Question 3 of 5
Which of the following statements is FALSE regarding the use of qualitative and quantitative data in scientific research?
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.
Question 4 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.
Question 5 of 5
Which of the following is not a type of muscle tissue?
Correct Answer: D
Rationale: The correct answer is D: Adipose. Adipose tissue is a type of connective tissue that stores fat, not a type of muscle tissue. Skeletal, smooth, and cardiac tissues are the three main types of muscle tissue. Skeletal muscles are attached to bones, smooth muscles are found in organs and blood vessels, and cardiac muscles are specific to the heart. Adipose tissue does not have the contractile properties of muscle tissue, making it the correct choice.
