Beet Cell Lab Purpose: The purpose of this Lab was to see how much pressure or stress the beet tissue would hold. Hypothesis: I hypothesize that the higher % of the solvent that the higher the colour intensity will be shown on the ph colour scale. The lower the solvent then the less colour shown. Materials: *Test Tubes (4) *Cork Borer *Beets *Water *1% Acetone *50% Acetone *1% Methanol *50% Methanol Procedure: *Cut 4 uniform cylinders of beet using a cork borer with a 5-mm

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

conditions do cells gain or lose water? Did water move into the cell or out of the cell while it was surrounded by hypotonic solution? The water moved into the cell‚ because there was less water inside the cell than outside (there were fewer water molecules inside). 2. In which direction did the water move though the cell membrane when the cell was surrounded by the hypertonic solution? The water moved out of the cell because there was a higher concentration of water inside the cell than outside

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers

organelle in any eukaryotic cell. It is enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores. Within the nucleus is the DNA responsible for providing the cell with its unique characteristics. The DNA is similar in every cell of the body‚ but depending on the specific cell type‚ some genes may be turned on or off - that’s why a liver cell is different from a muscle cell‚ and a muscle cell is different from a fat cell. When a cell is dividing‚ the nuclear
