D. a cell nucleus divides
I believe in both carbon dioxide and oxygen
It’s the second one. In photosynthesis plants take carbon dioxide and water to make glucose and oxygen. Hope this helps!
I believe it's "pollen".
When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.
Hope this helps!
The part of the cell membrane that acts as a barrier are the Hydrophobic tails!
