1. The lab exercise requires that one use a microscope in which a commercially prepared slide of silk fibers is supplied. What should one do to complete the microscope setup starting from the point in which the microscope is plugged in and placed on the lab bench in front of the user to the point at which the slide is being clamped onto the stage. One can assume that the microscope is set up such that the stage is in its lowest position and that the low power

It will be easy to discover and count the heart rate of Daphnia as long as the Microscope is set up correctly. The goal of this project is to measure the heart rate of Daphnia whether it will increase or decrease after a caffeine is added. Basically this lab report will explain the experiments on Daphnia and observe the effect of different
