poured into the Hydrogen peroxide filled flask. When the catalase and Hydrogen peroxide meet a reaction will occur and the hydrogen peroxide will be broken down into water and oxygen. The oxygen released from the reaction will be recorded by the Gas Pressure sensor. This step will be repeated five times for each necessary trial‚ then the next catalase extract will be

oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest was helium. In fact‚ helium and lab gas had a density below 0. Anyways

There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used.

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

Homeostasis Lab: The Effects of Exercise on Homeostasis Purpose: To discover the effect that various levels of exercise have on specific body parameters. Hypothesis: If a subject walks up and down a flight of stairs for eight minutes‚ then they start to sweat more‚ their heart rate‚ body temperature‚ and breathing rate will increase‚ and there will be a change in their skin color on their arms and face‚ because the body will be trying to maintain homeostasis. Materials: You will

The Gene Lab 1. Introduction The purpose of this report is to inform dog breeders of a very common genetic disease known as Progressive retinal atrophy (PRA). The report will also inform buyers of the disease so they are aware of the disorder and they can check to dog’s pedigree for the disease. PRA could affect any dog‚ as a result of this it is recommended that the offspring should be examined by a board-certified veterinary ophthalmologist and screened for the existence of the disorder.

the normal 30 minutes which could mean that the potatoes did not go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time
