Question

which statement is an inference? a thermometer shows that the air temperature is 56°f. a mineral sample of galena produced a gray - black streak when test based on previous data, ten hurricanes may occur in the year 2013. a weather vane indicates the wind is coming from the west. 8 multiple choice 2 points the current knowledge concerning cells is the result of the investigations observations of many scientists. the work of these scientists forms a well body of knowledge about cells. this body of knowledge is an example of hypothesis controlled experiment theory research plan 9 multiple choice 2 points in order to advance to the level of a theory, a hypothesis should be obviously accepted by most people. a fully functional experiment. in alignment with past theories. repeatedly confirmed by experimentation. 10 multiple choice 2 points conclusions based on an experiment are most likely to be accepted when they are consistent with experimental data and observations they are derived from investigations having many experimental variables scientists agree that only one hypothesis has been tested

Explanation:

• Question 8: A theory is a well - established body of knowledge based on the investigations and observations of many scientists. The knowledge about cells is built over time through multiple studies, which fits the definition of a theory. A hypothesis is a tentative explanation, a controlled experiment is a method of testing, and a research plan is a design for an investigation.
• Question 9: For a hypothesis to become a theory, it needs to be repeatedly confirmed by experimentation. Popular acceptance (not based on evidence) is not sufficient. A hypothesis is not an experiment itself. Alignment with past theories is not the key factor; experimental confirmation is.
• Question 10: Conclusions are most likely to be accepted when they are consistent with experimental data and observations. Having many experimental variables can complicate and make results less reliable. Testing only one hypothesis doesn't ensure acceptance if the data is inconsistent. Hypotheses based on one experimental design lack the robustness of multiple confirmations.

Answer:

• Question 8: theory
• Question 9: repeatedly confirmed by experimentation
• Question 10: they are consistent with experimental data and observations
