Jane sets up an experiment to find out if kittens prefer skim milk, 2% milk, or whole milk. she puts out a cup of skim milk for 5 kittens and then measured how much the kittens drank during a day. the next day, she used the same kittens and put out a cup of 2% milk. the last day, she used the same kittens and put out a cup of whole milk. she discovered that the kittens preferred whole milk. there are many problems with this experiment. each of the following would improve the experiment except which one?

answer: if she breaths she a thho

explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
