A teacher had her students down hypothesis about an experiment wich is a valid hypothesis.
energy gets transferred among all the organisms of a food chain
if people like the smell of burning wood, then they would not like the smell of gasoline
if earthquakes occur then tornado could occur at the same time
all living organisms are made from at least one cell
The valid hypothesis among the given options is: "All living organisms are made from at least one cell."
The valid hypothesis among the options provided is:
- Energy gets transferred among all the organisms of a food chain.
A valid hypothesis is a testable statement that proposes a possible explanation to a specific phenomenon. In this case, the hypothesis suggests that energy transfer occurs within a food chain, which can be tested and observed in an experiment.
To determine which of the hypotheses is valid, we need to evaluate each one.
1) "Energy gets transferred among all the organisms of a food chain."
To validate this hypothesis, we can look for scientific evidence or observations about energy transfer in food chains. You can find information from biology textbooks, scientific studies, or online sources. Look for information on concepts like trophic levels, energy flow, and the transfer of energy through different organisms in a food chain.
2) "If people like the smell of burning wood, then they would not like the smell of gasoline."
This hypothesis can be tested through surveys or experiments. To gather data, you can create a survey asking participants to rate their preferences for different smells, including burning wood and gasoline. Analyze the data and look for correlations or patterns between participants who like the smell of burning wood and their attitudes toward the smell of gasoline.
3) "If earthquakes occur, then tornadoes could occur at the same time."
To investigate this hypothesis, you would need to analyze data on earthquake and tornado occurrences. Look for correlations between the two phenomena in different regions and over different time periods. Scientific journals, weather databases, or geological surveys can provide reliable sources of information to study the relationship between earthquakes and tornadoes.
4) "All living organisms are made from at least one cell."
This hypothesis is based on the fundamental principle of cell theory. To confirm its validity, you can refer to biology textbooks, scientific research papers, or educational websites that explicitly state the cell theory. These sources should highlight that all living organisms are composed of one or more cells.
Remember, for any hypothesis, it is essential to gather and evaluate scientific evidence or observations to reach valid conclusions.
