Answer:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.
I believe the correct answer from the choices listed above is option D. Based on the time scale, it would be that <span>the atmosphere was formed after microscopic life appeared on Earth that is the correct inference. It is very clear in the picture as the microorganisms appear before the atmosphere. Hope this answers the question. </span>

Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.
Answer:
C would be the incorrect statement.
Explanation:
When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.
Hope this helps :)
