The most important thing to note is that the vector does not get affected by the disease they are carrying. The vector can move from place to place without any hindrance and spread the disease to far away areas. This is the reason that vector borne diseases occur in large areas. Mosquitoes and flies are common vectors that carry germs and spread from people to people.
Cell division in Prokaryotes is more simple because prokaryotes only have one circular chromosome, no nucleus, and few other organelles. However, eukaryotes have multiple chromosomes contained within a nucleus and many other organelles.
Aerobic has to do with oxygen but, anaerobic has to do without oxygen. Glycolysis is included in anaerobic, creating 2 ATPS.
If I fertilize plant A with fish meal and plant B with artificial fertilizers, I will be able to prove that fish meal is better than artificial fertilizers.

In our example above, the scientist needs to keep all the variables consistent for both plants, except that one plant is fed fish meal and the other plant is fed with artificial fertilizers.
