Tell a story from the perspective of an oxygen molecule traveling thorugh the body.

Explanation:

Me oxygen enters into the human body as a component of air through human nostrils. I enter into the windpipe which get divided into branchial tubes. These bronchial tubes are distributed in the lungs. The brochioles are tiny air sacs which further distributed to the alveoli. I move to alveoli and then further to the capillaries. Through capillaries i move to other body parts along with the blood.

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.

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.
