Amutation between a cytosine and a thymine is known as a ( fill in the blank using a one word answer, spelling counts).

Transition

Explanation:

Transition is a kind of mutation that occurs when a purine base is substituted by another purine base (or a pyrimidine base by another pyrimidine base).

Therefore, since cytosine and thymine are both pyrimidine bases, the mutation is known as TRANSITION

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 eggs of the insects should be the first thing collected at the scene.
