Lab Report #1 Facilitated diffusion By: Kelsey Clark Biology 2401 C1L Dr. Fanini October 2‚ 2017 Facilitated Diffusion Facilitated Diffusion is a type of passive transport that allows for lipid insoluble molecules or molecules that are too large to pass through a membrane. The molecules are able to pass through by binding with protein carrier molecules and moving down the concentration gradient. The rate of diffusion will continue to increase until the carrier proteins are saturated

-Get into the world of Fun! This handout is about population ecology‚ YEAH!!!- [Chapter 53 Handout] What is a population? Population: Group of individuals of the same specie living in the same general area. * Why is population ecology important? * Allows for monitoring of organisms impact on environment and also helps to regulate impact. * Helps to preserve populations of organisms. * Ecologists efforts have helped to preserve endangered animals such as the BALD EAGLE TOOLS

influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent was to measure

Title: Egg Osmosis Purpose: The purpose for doing this lab is to show how Osmosis takes place. It is supposed to show how the eggs would react to a change in their environment. The way to show how it would change would be putting eggs in different controlled environments. Each of the eggs will be put in three different environments. Vinegar‚ Karo Syrup‚ and water. Each egg will have to have a documented reaction that each will have. Introduction: The lab will allow us to see and explain each

The cells in the solutions of distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions

making the bacteria take on various phenotypic characteristics. Background Information: Genetic transformation is one of the most important processes in biotechnology. Essentially‚ genetic transformation involves the process where a cell (in this lab‚ a bacterial cell) takes up foreign DNA from its surroundings and incorporates it into its own DNA. This gene transfer is accomplished with the aid of a plasmid‚ a

The plants used in this experiment are called Wisconsin fast plants‚ due to their extremely short life cycle. In just 40 days‚ the plants germinate‚ grow‚ flower‚ and die‚ which makes them convenient to study in classroom experiments. They are members of the crucifer family and are related to other plants like broccoli and cabbage. In this experiment‚ 8 fast plant seeds were planted in a self-constructed bottle-growing system‚ and they were left to grow for 7-14 days. The Net Primary Productivity

S5E1 Gaseous Diffusion 1.0 ABSTRACT In this experiment‚ our objective is to find out the gas diffusion coefficient‚ D of acetone in the air. This experiment is conducted at a temperature of 50ºC and atmospheric pressure. The method that is applied to conduct this experiment is called the Winkleman method where the level of acetone (Z) is determined every 15 minutes by using a microscope. With the level of acetone being determined‚ a graph of t/L+Lo (min /mm) vs. L-Lo (mm) is plotted and the

In the structure of a eukaryotic plant cell consist of a membrane-closed nuclei and organelles‚ since they developed a process in which they manufacture their own food. The Chlorophyll‚ which gives the plant the green color captures sunlight to convert water and carbon dioxide into glucose and carbs‚ in which are used for the repetition of the cycle. Not only does the plant cell consist of a membrane‚ unlike other eukaryotic cells it additionally

Egg Osmosis Lab The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked
