Hey guys, i need help with these questions for my bio class and i would love it if you could!

1) How would knowing the carbon cycle be useful to biologist in making a study of food chains or food webs? *I finished this one*

2)The proteins in the cells of a wheat plant are different from the proteins in your cells. How can the difference be explained? What must happen when you use wheat as a nutrient for the formation of your proteins?

3)many botanists believe that the concentration of carbon dioxide in the air was much greater during the carboniferous period, when most of the large coal deposits were being formed, thean it is all present. What might be the basis for their belief?

4) in what ways do you contribute to the carbon cycle?

5) Are animals needed for carbon to cycle within a community? Explain

6) Do you think a sugar moecule has order and organization? How does this question relate the use of sugar as a source of energy by living things?

7) Imagine you could count the numbers of structures in one of your cells/ For each of the following pairs, choose one that would be more numerious in each cell: (a) atoms or prtons (b) nucleotides or DNA molecules;(d) enzymes or amino acids

8) In terms of calories why do you think seeds(small structures containing youg plants) and high in fat content? Examples are the peanut corn and sunflower seeds from which we get cooking oils. Why are such seeds good sources of food for humans.

9) Apply what you have learned about carbon dioxide and the carbon cycle to global warming. Suppose the temperature of the earth inreased by 5 c. What effects might this have? What if the tempeture increased 15 c?


Ok guys sorry for the crappy typing. I just got raped by all my teachers with all this homework and i really need help with Bio because because its my weakest subject!!

Also no crappy replies like i smell poo or something.
