Science TEAS Practice Test

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.

Correct Answer: C

Rationale: The correct answer is C: White blood cells. White blood cells, specifically lymphocytes, are responsible for producing antibodies as part of the immune response. Platelets are involved in blood clotting, not antibody production. Red blood cells carry oxygen and do not play a role in immune responses. Plasma cells are a type of white blood cell that produces antibodies, but they are a specialized subset of white blood cells and not the main component responsible for antibody production.

Correct Answer: C

Rationale: The correct answer is C: Circulatory system. This system, composed of the heart, blood vessels, and blood, is responsible for transporting nutrients, gases, and wastes throughout the body. The heart pumps blood carrying oxygen and nutrients to cells and removes waste products. The blood vessels distribute these substances to tissues and organs. The respiratory system (A) is responsible for gas exchange but not for transporting nutrients and wastes. The digestive system (B) processes food and absorbs nutrients but does not transport gases. The nervous system (D) coordinates body functions and transmits signals but does not transport nutrients, gases, or wastes.

Correct Answer: B

Rationale: The correct answer is B: Liver. The liver is primarily responsible for detoxification in the body as it processes and removes toxins, drugs, and other harmful substances from the bloodstream. It metabolizes these toxins into less harmful compounds that can be excreted from the body. The kidney, although important for filtering waste and regulating electrolytes, is not primarily responsible for detoxification. The lung primarily functions in gas exchange, and the heart is responsible for pumping blood throughout the body, not for detoxification. Therefore, the liver is the correct choice for the organ primarily responsible for detoxification.

Correct Answer: B

Rationale: The correct answer is B: Endocrine system. The adrenal glands are a crucial part of the endocrine system as they produce hormones such as cortisol and adrenaline. These hormones regulate various bodily functions like metabolism, stress response, and blood pressure. The immune system (A) is responsible for defending the body against pathogens, not producing hormones. The lymphatic system (C) is involved in immunity and fluid balance, but not hormone production. The respiratory system (D) is responsible for gas exchange in the body, not hormone regulation. Therefore, the adrenal glands being part of the endocrine system is the most accurate choice.
