After collecting samples of the material found growing on last month's leftovers at the back of your fridge, you realize that yo
u have discovered a new type of organism. You find that the cells have distinct microscopic subunits within them. Further, several of these subunits seem to be involved in the production and transfer of certain molecules. One molecule appears after a messenger molecule is sent from a subunit to another one. The first molecule then travels to another location, where it is covered in membrane and (eventually) released from the cell. What type of cells do you think these are?
Microscopic subunits within the cell represent the organelles found only in complex eukaryotic cell. The communication between those organelles via signal molecules are also a good example of the functioning of eukaryotic cell.
Eukaryotic cell is a cell that contains a nucleus and organelles, and is enclosed by a plasma membrane.
First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst.
