The investigation on the average mass of DNA with the mass of banana‚ strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana‚ strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome

MATERIAL AND METHODS Stability of cell membrane using pH For the lab experiment for testing the stability of beet cell membranes using pH‚ many materials were used as follows. Obtaining a beet we punch out cores‚ using a cork borer. After washing the cores we put each one inside a separate test tube‚ and added a different pH solution in each one. After 3 minutes in these exposure solutions‚ we took the beet out with a dissecting needle. Then transferred each beet to a separate test tube containing

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

NT1210 Chapter 4 Lab 4.1.1 Standards are put in place to make everything work together error free. Because Stability‚ Consistency‚ Minimization of packet errors. 4.1.2 Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult. 4.1.3 Hospitals‚ security systems‚ PA & recording studios. The drawback of STP cables is that they will increase the total cost of an installation.

Procedure Access the virtual lab and complete the experiments. Part One (Flame Test): 1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame: Barium-green Calcium-red Sodium-yellow Rubidium-purple Potassium-blue Lithium-pink 2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.: Unknown 1-yellow. I think it is Sodium because

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher
