Science TEAS Practice Test

Correct Answer: C

Rationale: The correct answer is C: An inference. This is because the statement "someone must have forgotten to water it" is not a direct observation but a conclusion drawn based on the observed condition of the dead flower. In making this statement, the speaker is connecting the lack of water to the flower being dead, which requires logical reasoning. A: A classification - This choice does not apply as the statement does not categorize or group anything. B: An observation - While the initial part of the statement is an observation (the flower is dead), the second part goes beyond just stating what is observed to drawing a conclusion based on that observation. D: A collection - This choice does not make sense in this context as the statement does not involve gathering or assembling items.

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: Tendons. Tendons are fibrous connective tissues that attach muscle to bone, allowing for movement. Ligaments (A) connect bone to bone, muscles (C) are the tissues responsible for movement, and bones (D) are the rigid structures that make up the skeletal system. Tendons play a crucial role in transmitting the force generated by muscles to move bones, making them the correct choice in this scenario.

Correct Answer: B

Rationale: The correct answer is B. If an organism is AB, it means they have alleles A and B. In gametes, each gamete carries only one allele. Therefore, gametes with AA are not possible as they lack the B allele. Gametes with AB are possible since they can carry either A or B allele. Gametes with BB are not possible as they lack the A allele. Gametes with AB are possible as they can carry either A or B allele.

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.
