150L: Introduction to Biology I Instructor: Dr. Bethany Bowling Osmosis and Diffusion Report Estimating the Osmolarity of Plant Cells--Potato YAO ZHANG 03/26/2012 Introduction: It is undeniable that all cells have the kinetic energy. It will led the cells move randomly around to others. For this molecular movement‚ there are two results that might happen. Diffusion is one of them. Diffusion is the movement of molecules that between the high concentration and the low concentration

Lab 1 – Ubiquity of Microbes Bacteria are the most widely distributed organisms in the biosphere. They are found in all different types of soil‚ water and even in the bodies of other living organisms. Every single place that humans have explored on the Earth‚ have shown to contain microbes. Bacteria are living organisms and like all living organisms‚ they require energy and carbon sources in order to metabolize and reproduce. And like all living organisms they respond to changes in their environment

Motion in 2D Simulation Go to http://phet.colorado.edu/simulations/sims.php?sim=Motion_in_2D and click on Run Now. 1) Once the simulation opens‚ click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. 1. The green vector moves in the direction of the mouse until the red ball catches up to it. 2. The blue and green vectors

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport‚ without requiring bulk motion. Thus‚ diffusion should not be confused with convection‚ or advections‚ which are other transport mechanisms that utilize bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach

effect of concentration of acid on the rate of diffusion in agar blocks? Aim: To investigate how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement of molecules along

Examples of active transport are endocytosis‚ exocytosis‚ and phagocytosis. Passive transport does not require energy it is powered by the concentration gradient of the molecule. Examples of passive transport are diffusion‚ facilitated diffusion‚ filtration‚ and osmosis. In our Osmosis Lab I used a Grade a large egg from the grocery store. Its circumference is 5 ½ inches it is smooth with no cracks. I carefully place the egg in a clear plastic cup and fill the cup with vinegar. I immediately notice

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements of
