Microevolution refers to changes that occur within a single species or group or organisms. Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type. For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls
The aim would be to determine the effect of different types of grass on the movement of a ball

Inferences can then be made from this results and then conclusions drawn subsequently.
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks
One of the main reasons why there is a need to create additional three kingdoms was due to the invention of the microscope. The scientific device paved way for a more intensive study of the tiny organisms most considered as single-celled which cannot be seen by the naked eye.
