Science TEAS Practice Test Questions

Question 1 of 5

Which of the following is NOT a component of the genitourinary system?

Correct Answer: C

Rationale: The correct answer is C: The rectum. The genitourinary system consists of organs involved in reproduction and waste elimination. The rectum is part of the digestive system, not the genitourinary system. The kidneys (A), urethra (B), and bladder (D) are all essential components directly involved in the production, storage, and elimination of urine. The rectum plays a role in the elimination of solid waste and is not part of the genitourinary system.

Question 2 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 3 of 5

Which system is responsible for transporting nutrients, gases, and wastes in the body?

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.

Question 4 of 5

The average life expectancy at birth in the United States at the beginning of the 21st century was about 75 years. The average life expectancy at birth in the middle of the 19th century was only about 40 years. Which of the following factors are likely to have contributed to the longer life expectancy in the 21st century? (Select the one that does not apply)

Correct Answer: A

Rationale: The correct answer is A: The human body has evolved to become more resilient to its environment. This statement is not likely to have contributed to the longer life expectancy in the 21st century. Evolution occurs over long periods of time, not within a span of a few hundred years. Advances in medical technology and treatments (B), higher standards of basic cleanliness (C), and the creation of vaccines (D) have all played significant roles in increasing life expectancy by preventing and treating diseases, improving overall health, and reducing mortality rates. These factors are directly linked to improvements in healthcare and sanitation practices, which have had a tangible impact on life expectancy.

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.
