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.
No rotted plants are in the limntic zone because the water is to deep for sunlight to reach them.
Tissues invaded by viruses, which attempt to replicate themselves by taking over cellular machinery, secrete small proteins called <span>interferon</span> to protect nearby cells and hinder further multiplication of the viruses.
