Question

andreas wrote the following hypothesis: \if the number of livestock on earth increases, then the amount of methane gas in the atmosphere will increase because cows produce methane gas as a by - product of digestion.\ what scientific question is his hypothesis most likely addressing? o what is the effect of livestock on the amount of methane gas? o what is the effect of livestock on earth? o what is the effect of methane gas on the atmosphere? o what is the effect of methane gas on digestion in livestock?

Explanation:

A hypothesis is a proposed explanation for a phenomenon. Andreas' hypothesis is about the relationship between the number of livestock (the independent variable) and the amount of methane gas (the dependent variable). The first option directly asks about the effect of livestock on methane gas, which aligns with the hypothesis. The second option is too broad as it doesn't mention methane. The third option flips the variables (focuses on methane's effect on atmosphere instead of livestock's effect on methane). The fourth option also has the variables reversed (methane's effect on digestion instead of livestock's effect on methane).

Answer:

What is the effect of livestock on the amount of methane gas?
