Different types of cells within an organism

a) are the same

b) do not have functions

c) serve different functions

d) can survive on there own

The correct option is C. Different types of cells within an organism serve different functions.

Explanation:

All kinds of cells found in the body emerge from the stem cells. The stem cells divide by a process of cell differentiation and make specialized cells. Each cell is specialized to perform its own functions. For example, nerve cells in the body transmit signals in the body whereas white blood cells of the body are involved in providing immunity to the body. The specialized cells work together and make specialized tissues.

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.

the answer would be..
