Can someone answer these questions for me 20pts

1. (Carnivorous) They don't rely as much on the mechanical breakdown of foods in the mouth as much as they usually eat their prey whole. They also have U-shaped stomachs.They regurgitate indigestible things (e.g. Large Bones). They have shorter, spiralling intestines, but this means it also has a large surface area.

2. One difference is that humans have lungs so that is used to oxygenate the blood while shark has gills. Another difference is that Sharks use the heat from their muscles, so rather then expelling it into the outside environment that actually use that to heat their blood and transfer the heat from warmer blood to passing colder blood.

3. I positioned my shark to be dorsal side up and have its ventral side facing down.

4. The pectoral girdle is in a location where the cartilage is very thick.

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.

i think its through the fallopian tube
