A teacher had her students write down hypotheses about an experiment. Which is a valid hypothesis?
A. Energy gets transferred among all the organisms of a food chain
B. All living organisms are made from at least one cell
C. If people like the smell of burning wood, then they would not like the smell of gasoline***
D. If earthquakes occur, the. Tornados could occur at the same time
The answer is “ IF PEOPLE LIKE THE SMELL OF BURNING WOOD, THEN THEY WOULD NOT LIKE THE SMELL OF GASOLINE”. I just took the the test and got it right
Ah, hypotheses, the playground of a scientist's imagination! Let's take a closer look at these options, shall we?
A. "Energy gets transferred among all the organisms of a food chain." Well, that's a pretty solid hypothesis focusing on the energy flow in a food chain. Kudos to option A!
B. "All living organisms are made from at least one cell." Ah, the good ol' cell theory! That's not just a hypothesis, my friend, it's a well-established scientific fact. So while it's a true statement, it doesn't quite fit the bill as a hypothesis.
C. "If people like the smell of burning wood, then they would not like the smell of gasoline." Ah, an olfactory experiment! This one's intriguing. However, it's more of a prediction rather than a hypothesis. A hypothesis would propose a cause-and-effect relationship between variables, but in this case, we're missing the "why" factor.
D. "If earthquakes occur, then tornados could occur at the same time." Oh boy, this hypothesis seems like it's cooking up quite a chaotic weather recipe! However, earthquakes and tornados are two separate phenomena with different causes, so this hypothesis doesn't quite hold water.
So, option A, "Energy gets transferred among all the organisms of a food chain," takes the trophy for being a valid hypothesis. Hooray for energy shuffling in food chains!
To determine which of the given options is a valid hypothesis, we need to understand what a hypothesis is. A hypothesis is an educated guess or prediction based on prior knowledge or observations. It is a statement that proposes a relationship between variables, which can be tested through experimentation.
Let's evaluate each option:
A. "Energy gets transferred among all the organisms of a food chain"
This is a valid hypothesis as it proposes a relationship between organisms in a food chain and the transfer of energy.
B. "All living organisms are made from at least one cell"
This is a valid hypothesis as it proposes a relationship between living organisms and the presence of cells.
C. "If people like the smell of burning wood, then they would not like the smell of gasoline"
This option is not a valid hypothesis because it does not propose a verifiable relationship between two variables. Additionally, individual preferences for smells are subjective and can vary.
D. "If earthquakes occur, then tornados could occur at the same time"
This option is not a valid hypothesis because it suggests a relationship between earthquakes and tornadoes, which is not supported by scientific evidence. Earthquakes and tornadoes are caused by entirely different natural phenomena.
Therefore, the valid hypotheses are options A and B.
I’m not sure if this is correct but I’m pretty sure it’s If Earthquakes occur, then tornados could occur at the same time. Let me know if this helped 😎
surely not C
the two smells are quite different, but surely there are people who like both.
what do you know about living things? ...
