How does the input of olfactory information to the brain differ from other sensory input pathways? a. it does not require the cortex for higher order processing. b. direct connections to the thalamus are not made before information reaches the cortex. c. the first direct connection is to the thalamus and not to the medulla. d. prior to making connections with the medulla, sensory input travels through the spinal cord?

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.

b.have there own function.
