Science TEAS Practice Test

1. In order to be included in the formation of a scientific conclusion, evidence must be:

Correct answer: B

Rationale: For scientific evidence to be included in the formation of a scientific conclusion, it must be reproducible. Reproducibility is a fundamental aspect of the scientific method, ensuring that the same experiment will yield the same results if repeated. This allows other researchers to verify the findings and conclusions drawn from the evidence, enhancing the reliability and validity of the scientific process. While quantitative data can be important in supporting evidence, it is not a strict requirement for evidence to be included in scientific conclusions. The term 'obvious' is subjective and does not necessarily guarantee the reliability or reproducibility of the evidence, making it an unreliable criterion for scientific conclusions. Therefore, choice B, reproducible, is the correct answer as it aligns with the fundamental principles of the scientific method, emphasizing the importance of replicating results for establishing reliable conclusions.

2. What is the function of the stratified cuboidal epithelium lining the salivary glands?

Correct answer: C

Rationale: The correct answer is C: Secretion. The stratified cuboidal epithelium lining the salivary glands is responsible for secretion. This type of epithelium, made of multiple layers of cube-shaped cells, is specialized for secretion and protection. In the salivary glands, these cells secrete saliva to aid in the digestion process. Choice A, Protection, is incorrect because while the epithelium does provide some level of protection, its primary function in the salivary glands is secretion. Choice B, Gas exchange, is incorrect as the salivary glands are not involved in gas exchange processes. Choice D, Absorption, is also incorrect as the main role of this epithelium in the salivary glands is not absorption but rather secretion of saliva.

3. What property best describes the characteristic that nuclear forces are much stronger than electromagnetic forces at the nuclear level?

Correct answer: A

Rationale: The correct answer is A: Short-range interaction. Nuclear forces are much stronger than electromagnetic forces at the nuclear level because they are short-range interactions that act over distances on the order of the size of an atomic nucleus. This short-range nature of nuclear forces allows them to be much stronger than the long-range electromagnetic forces, which weaken with distance according to the inverse square law. Choice B, long-range interaction, is incorrect because nuclear forces are short-range. Choice C, repulsive force, is incorrect as nuclear forces include both attractive and repulsive components. Choice D, dependent on charge only, is incorrect because nuclear forces are not solely determined by charge but also involve other factors like spin and isospin.

4. What is the name of the long bone found in the upper arm?

Correct answer: C

Rationale: The correct answer is the humerus. The humerus is the long bone located in the upper arm, between the shoulder and elbow. Option A, Femur, is incorrect as it is the long bone found in the thigh. Option B, Tibia, is incorrect as it is a long bone found in the lower leg. Option D, Radius, is incorrect as it is a bone located in the forearm, not the upper arm.

5. Which of the following is a function of the kidneys?

Correct answer: B

Rationale: The correct answer is B: 'To filter waste from the blood.' The kidneys are vital organs responsible for filtering waste products from the blood, regulating fluid and electrolyte balance, and producing urine. Choice A is incorrect because the production of digestive enzymes primarily occurs in the pancreas and salivary glands. Choice C is incorrect as the production of white blood cells mainly takes place in the bone marrow and lymphatic system. Choice D is incorrect as the production of red blood cells occurs in the bone marrow.
