You can carry out a test ,
1- take a sample of the air in a test tube
2-add limewater to the test tube
3- result : if it turns milky/cloudy it has microorganisms
4- reason: because every microorganism respires , and so it produces Carbon dioxide .
and limewater is the test to show the presence of Carbon dioxide .
It should be 1000x which is the total magnification of the whole thing... I believe. Would you happen to be doing a microscope quiz
1. All cells are similar in structure and function.
2. Cell contains hereditary information that is passed from cell to cell during cell division.
3. Living cells can be created from dead cells. All cells perform similar metabolic activities.
hope this helps
