Question

what is the following statement? \if a substance is exposed to uv light, then it will change\ (options: a observation, b inference, c hypothesis). question 39 (1 point) what is the following statement? \the plant needs more sunlight or its going to die.\ (options: a observation selected, b inference, c hypothesis).

Explanation:

First Question (about UV light statement)

A hypothesis is a testable prediction in an "if - then" format. The statement "If a substance is exposed to UV light, then it will change" is a prediction of what will happen under a certain condition, fitting the definition of a hypothesis. Observation is describing what is seen, and inference is a conclusion from observations, so this is a hypothesis.

An inference is a conclusion or interpretation based on observations or prior knowledge. The statement "The plant needs more sunlight or it’s going to die" is an interpretation of the plant's situation (needing sunlight to survive), not a direct observation (which would be describing the plant's appearance, size, etc.) or a hypothesis (which is a testable prediction). So it is an inference.

Answer:

c. Hypothesis
