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.
Because the molecules that are being transported is moving against its concentration gradient. in other words, its moving from where its low in concentration to where its high in concentration
What happens to energy as it flows through the food chain and food webs of an ecosystem The chemical energy storied as nutrients in the bodies and wastes of organisms flows through ecosystems from one trophic level to the next and through this flow energy also is lost as heat.Explanation:
