JavaArray An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation‚ its length is fixed. You have seen an example of arrays already‚ in the main method of the "Hello World!" application. This section discusses arrays in greater detail. An array of 10 elements. Each item in an array is called an element‚ and each element is accessed by its numerical index. As shown in the preceding

The Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of

Experiment: Turgor in Potato Tissue 1. We labelled three test tubes A‚ B‚ C‚ D and added initials of people in our group. 2. Used a syringe or graduated pipette to put 20 cm3water in tube A and 10 cm3 in tube B. 3. Put 20 cm3 of 17% solution in tube C and 10 cm3 in tube B; put 20 cm3 pure sucrose solutions in tube D. 4. Working on the dissecting board I cut the ends off large potato. I was careful with the knife and cut it onto the dissecting board away from myself. 5. Used a cork

Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when the molecules in high concentration are too large to move through the membrane. Three factors that determine cell membrane permeability are shape‚ size‚ and polarity. For this experiment‚ it must
