The first land plants appeared around 470 million years ago. All of the following are evolutionary traits that enabled plants to survive in a dry environment EXCEPT: a. Cell walls made up of cellulose.
b. Roots and root hairs, which absorb water and nutrients from the soil.
c. Photosynthetic pigments, which absorb light energy and provide energy to carry out photosynthesis.
d. Stomates, which open close to exchange photosynthetic gases and minimize water loss.

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.

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati

the answer u all are looking for is 4000000000000000000000 million years.
