    Camren Allen Concept Check 1.1: 1.) A biosphere has an ecosystem that consists of all living things in an area. An ecosystem consists of communities which hold organisms that live in a specific area. A community consists of populations of all the individual organisms in a specific area. A population consists of living things called organisms. Organisms break down into organs and organ systems which are more complex parts of organisms. Organs and Organ Systems are created by tissues which is

    Introduction: This lab helps further our understanding of essential principles behind diffusion and osmosis. Permeability‚ concentration gradients‚ plasmolysis‚ water potential‚ and equilibrium were also concepts that were delved into in this lab. Understanding how diffusion and osmosis works is essential to understanding biology. Each time a cell has something move into or out of it‚ some sort of principle studied in this lab is occurring. Diffusionosmosis‚ and passive and active transport are

    Alisha Prakash Biol 111-513 The Properties of Water; Osmosis and Diffusion Hypothesis: When animal and plant cells are placed in a solution‚ the movement of water is effected by the solute concentration of the solution. If animal and plant cells are placed in a more concentrated solution‚ the solution becomes hypertonic to the cells‚ causing water to exit the cells. This changes the appearance of the cells‚ causing the cells to look darker (more concentrated) and shriveled up. Null Hypothesis:

    Danielle Christian AP Bio FRQ #2 January 22nd‚ 2013 A.) Graph #1 A.) Calculation The rate of reaction from 0-30 minutes is 0.34667; r=10.4μM /30 minutes B.) Explanation The reaction was observed after 30 minutes because the reaction rate eventually slows down and the enzyme reaches its maximum potential. Since the enzyme is using the substrate so quickly‚ the substrates concentration depletes. That means the rate will slow down. Our graph shows that after about 40 minutes‚ the enzyme

Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

    Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for
