Question

you decide to investigate and conduct an experiment to find the reason.

you begin with the question, \how does temperature affect how often crickets chirp?\

select the statement(s) that would be an appropriate hypothesis when conducting the investigation above.

• if the cricket is happy, then it will chirp more often.
• if it is winter, then all the crickets will die.
• crickets only chirp in the summer months.
• if the temperature is cold, then the crickets will chirp less often.
• if the temperature is warm, then the crickets will chirp more often.

Explanation:

To determine appropriate hypotheses, we analyze each option based on the research question "How does temperature affect how often crickets chirp?":

1. "If the cricket is happy, then it will chirp more often": "Happiness" is not related to temperature, so this is irrelevant.
2. "If it is winter, then all the crickets will die": This focuses on survival (not chirping frequency) and season (not direct temperature), so it is irrelevant.
3. "Crickets only chirp in the summer months": This focuses on season (not direct temperature) and is a statement of "only" (not a testable hypothesis about frequency change), so it is irrelevant.
4. "If the temperature is cold, then the crickets will chirp less often": This directly links cold temperature to decreased chirping frequency, addressing the research question.
5. "If the temperature is warm, then the crickets will chirp more often": This directly links warm temperature to increased chirping frequency, addressing the research question.

Answer:

D. If the temperature is cold, then the crickets will chirp less often
E. If the temperature is warm, then the crickets will chirp more often
