Meghann Kiphart AP Biology Lab Report Number One Mrs. Irvine Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of water

Jhoselyn Adames June/12/2012 Scientific Critique of "_Osmosis Jones_" SYNOPSIS The 2001 film‚ _"Osmosis Jones"_‚ focuses on the representation of the human organism and the daily conflicts a body faces in order to maintain function. The film _"Osmosis Jones"_ is a film that tries to capture the attention of children ages eight to fourteen‚ by exposing the mechanisms of the human body. It is able to reveal the dangers of maintaining an unhealthy diet and some of the consequences that are associated

he mass and length of the potato piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length

Osmosis Practical Report Introduction: To determine the biological changes that occur to potato cores over a period of time in different solutions of sucrose and to relate these changes to the phenomenon of osmosis. Method: We soaked several discs of potato cuted using a cork borer with around 1 centimeter of diameter and 2 milimeters of lenght into sucrose solutions with a different range of concentrations from 0 to 1.0M. Then we weighed all the potato

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the
