Biology I Post Labs

In this lab, two experiments were performed. The overall finding of the first experiment was that there is a greater number of flies with red eyes than black eyes. In the second experiment, we found that flies with wings and red eyes had the greatest amount, while flies without wings and sepia eyes ...

In this lab, the number of untreated cells and treated cells was counted during interphase and the dividing phase.

This post lab summarizes the methods of the experiment. This includes the following: gloves worn to handle acidic and basic solutions, eleven cuvettes were prepared, and replicate samples were made for each pH value.

In this lab, the absorbance and mean absorbance was found for three different NaCl solutions. Observations were made based on the color of the solutions.

This is an introduction to the purpose of the lab, which is to study the effects of osmosis and permeability of cells.

The overall finding of the experiment was that the non-starved Tetrahymena cells have a greater number of vacuoles than the starved Tetrahymena cells. This was determined by observing starved and non-starved Tetrahymena cells under a microscope at different times and counting the number of vacuoles ...
