Identify which statement below is a hypothesis, and explain why. How could you determine whether the hypothesis is correct? a. Ocean water is too salty.
b. water heats faster if it contains salt.
c. Space probes have discovered small amounts of water on the moon.

b.

I would heat 2 equal quantities of water, one containing salt and one without with equal conditions (container, heat source, etc) and compare the amount of time it takes to heat from an equal starting point to an equal finish point.

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.

the fossil record provides evidence of a common ancestor to many species.
