In what ways are fats and steroids similar to each other, and in what ways are they different? Fats and steroids are both hydrophilic lipids, but fats help with metabolism while steroids provide insulation.
Fats and steroids are both hydrophobic lipids, but fats serve as energy while steroids serve as hormones.
Steroids contain a four-carbon ring while fats consist of glycerol and fatty acids, but both are proteins.
Steroids help with transport while fats store energy, but both are proteins.

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.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
