3. [bws.02] which of these is an example of a hypothesis? observe a plant kept in the dark wonder why plants grow well in sunlight leaves may change color due to temperature add different quantities of water to three potted plants

Option C, Leaves may change color due to temperature

Explanation:

Hypothesis is basically an assumption which is then examined based on practical grounds and can be proven false or true with logical consequences.  

Here, the assumption “leaves may change color due to temperature” is an assumption which can be tried and tested for establishing its ethnicity.  

While all other statements such as “observe a plant kept in the dark” and “add different quantities of water to three potted plants “ are  simple statements  in which something is being done/or asked to be done. While in statement “add different quantities of water to three potted plants” is a question about a pre established fact and hence it cannot be considered as an assumption.

Thus, option C is correct.

the answer is c

explanation:

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.
