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.

Answer:
The animal cells produce the collagen but the plant cell does not produce collagen that responsible for producing the complex structure of protein and carbohydrates that is called extracellular matrix cell. Collagen is an important protein that provides strength to the structural integrity. On the other hand, the plant has not collagen so they have their extracellular supportive structure. The cell wall is so rigid and covered by the cell that protects it that provides shape and support to it. The plant cell also made up of molecules and these are called cellulose. These cellulose structured into the fibers that are called micro-fibrils
Answer:
Carbon can bond with many elements
Explanation:
Carbon can bond with many elements, including itself, to form macromolecules. Moreover, it can form four bonds, and that makes possible many different arrangements of the atoms in the molecules.
A is <em>wron</em>g. Carbon is among the seven smallest elements in the Periodic Table.
C is <em>wrong</em>. Carbon is found in living things because it can form macromolecules, not the other way around.
D is <em>wrong</em>. Carbon can bond with many other elements beside itself.
