PsyDAG you are on this site too so stop acting like you are not cheating... anyways well do anyone got the answer I also need it

The answer is:

The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.
o7

Just respond I need the answers stop fighting. Not to be rude. also don't talk about others about cheating when your in here. Your here for a reason and it's not to just start fights. 10 year old kid. so calls people "cheaters"

Wow

Ragahahah thanka uuuu

Can somebody help me with question 1? Or is this the wrong site for question number 1???

We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.

What choices do you choose?

Choices do not need to be duplicated.
