Question

a student wondered if butterflies would show any differences in their wing color if, as caterpillars, they were grown in the dark or grown in bright white light. which statement would be a possible hypothesis for an experiment to test this idea? 1. caterpillars exposed to bright white light will show more blue and green in their wings when they become butterflies than caterpillars kept in the dark. 2. will caterpillars kept in the dark have brighter wings when they become butterflies than caterpillars exposed to bright white light? 3. ten caterpillars will be kept in the dark and ten caterpillars will be exposed to bright white light and allowed to develop into butterflies. 4. results show that caterpillars kept in the dark and those exposed to bright white light had the same wing color when they became butterflies.

Explanation:

Step1: Understand the concept of hypothesis

A hypothesis is a testable prediction.

Step2: Analyze each option

• Option 1: "Caterpillars exposed to bright white light will show more blue and green in their wings when they become butterflies than caterpillars kept in the dark" is a prediction that can be tested by an experiment (comparing wing colors of two groups of caterpillars - one in light, one in dark).
• Option 2: "Will caterpillars kept in the dark have brighter wings when they become butterflies than caterpillars exposed to bright white light?" is a question, not a hypothesis (hypothesis is a statement, not a question).
• Option 3: "Ten caterpillars will be kept in the dark and ten caterpillars will be exposed to bright white light and allowed to develop into butterflies" is a description of an experimental setup, not a hypothesis.
• Option 4: "Results show that caterpillars kept in the dark and those exposed to bright white light had the same wing color when they became butterflies" is a result statement, not a hypothesis.

Answer:

1. Caterpillars exposed to bright white light will show more blue and green in their wings when they become butterflies than caterpillars kept in the dark.
