Which of the following statements about minerals is false? a. minerals reflect light in different ways. b. the color of a mineral's powder doesn't change. c. the densities of many minerals are quite similar. d. a mineral can break in only one way.

B. The color of a mineral's powder doesn't change.

C. The densities of many minerals are quite similar.

D. A mineral can break in only one way.

A mineral is a naturally occurring inorganic compound. It is a chemical compound that usually found in crystalline form. The color of the mineral's powder can change because of the oxidation or reduction of particles present in it. The density of many minerals cannot be same because all mineral particles exhibit different composition of atoms or molecules which are responsible for physical and chemical structure of minerals. Hence, minerals vary in density. A mineral can be broken down into many ways like fracture, cleavage and other methods.  

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
