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. Diffusion‚ osmosis‚ and passive and active transport are

Lab Report 1: Natural Selection Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon‚ Fork‚ chopstick‚ and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food‚ the environmental chances‚ and see who

The purpose of this lab was to understand that because substances have different properties‚ such as mass‚ that can be separated by chromatography. In our experiment‚ we chose 4 different color source to separate in water. We made sure that all the sources were water soluble because only polar substances will dissolve in water. We chose a black wet-erase marker‚ a red marker‚ a green marker‚ and mixed food coloring to test. The chromatography paper was split into 4 sections‚ about 2 cm above the

This semester in English 101 has been very demanding for me. In previous years‚ I generally completed my writing assignments with ease and without having to put much thought or effort into them‚ but this year‚ I was required to work for many hours on each of my papers and to proofread them many times in order to receive a good grade. For example‚ I learned that if I wanted to reach my audience‚ I had to organize my paper in such a way that everyone could easily understand the organization and the

DENSITY OF LIQUIDS AND SOLIDS by Lab instructor: Due date: Results and discussion: The purpose of the experiment was to determine the densities of the unknown liquid and solid as precisely and accurately as possible in order to identify them. It was carried out first on distilled water in order to rule out systematic errors. A 10 mL beaker was placed on a top pan balance and “tared”. The beaker was then removed and 10 mL of distilled water was pipetted into it before it was placed
