Answer:
b
Explanation:
cause I had the same question
<span>Alright.. this is what I have in mind... then you can judge if I'm totally crazy:
As in any other experiment we wish to only hold 1 variable, while other thinkable variables are held constant.
In addtion to that we need to ref. soil and call that 0.
Now some theory: We know from medicals they can have synergetic effect if mixed. Same can go for nutrients, we therefor test each soil mixed and alone and see the effect.
We call the nutrients A, B and C, (continue with more if you like)
Now this is our setups:
0, A, B, C, AB, AC, BC, ABC.
In this way we can make compare to a ref soil (0) and also check for synergetic effects... this is a bit considered a multivariable experiment, but we also have A, B and C as ref. against the mixed soils.</span>
Mars' atmosphere is made mostly of carbon dioxide, much like Venus. It is not as hot as Venus because the Martian atmosphere is extremely thin. Venus has a thick layer of carbon dioxide gas surrounding the planet. This is why it is the hottest planet in the solar system even though it is not the closest to the sun. Carbon dioxide is a greenhouse gas so it has the ability to trap infrared radiation. The atmosphere on Mars is thin and so it will not trap as much heat as the Venusian atmosphere.
