two different ecosystems will be explored and the level of their biodiversity on certain area. Research question “To what extend is one ecosystem more diverse than other one?” Hypothesis If ecosystem has more number of species and organisms within those species‚ it will have higher biodiversity. Justification of hypothesis According to formula for Simpson`s diversity index‚ D = N (N-1) / Σ n (n-1)‚ where N is total number of organisms‚ while n is sum of individuals within a specie‚ we can see that

Hanging at a Constant Determining the effect mass has on acceleration Block 5 11/25/12 Purpose: The purpose of this lab is to determine the effect of additional mass added to a cart’s existing mass‚ without changing the applied force‚ on the acceleration of the cart. We will test this effect by hanging a constant mass to a cart and use a computer program‚ LoggerPro‚ to calculate the acceleration which is expressed through the

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

Introduction: There are two main types of passive transport; diffusion and filtration (Marieb 68). In this experiment the focus is the importance of diffusion‚ the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse). Diffusion or osmosis occurs until dynamic equilibrium is reached‚ or has been reached

Botany Lab ------------------------------------------------- Introduction This study observed the effects of different body fluids and solutions relative to breaking down bacteria‚ specifically in the human body. The enzymes we studied‚ lysozomes‚ help the body lyse‚ or break down bacteria by targeting peptidoglycan in bacterial walls. The solutions and fluids studied were saliva‚ mucus‚ tears‚ a stock solution of lysozomes‚ and distilled water. The solutions were placed in agar containing Micrococcus

Experimental Laboratory Report: An investigation into the rate of osmosis Liana Gohery - 98332250 12/12/2014 Word count - ………3000……….. 1. Abstract This study was conducted to investigate the effect of concentration gradients on the rate of osmosis. Osmosis is the cellular transport of water‚ this study was conducted to show the significance of the rate at which this occurs. Dialysis bags were filled with three different concentrations of sucrose solutions and two with water. They were

Biology 101 Popcorn experiment Lab partners Robert Barham Michelle hall Diva Mancada Kelley Pritt 1 Introduction Popcorn‚ or popping corn‚ is a type of corn which explodes from a kernel and puffs up when heated. It is a popular snack food‚ especially in movie theaters. Popcorn can be salted or sweetened. Air popped popcorn is naturally high in fiber‚ low in calories and fat‚ contains no sodium and is sugar free. This can make it an attractive snack for people with caloric or

Meiosis and Genetic Diversity in Sordaria 979554296 Biology 110 Lab Introduction: In Israel there exists multiple spots in the mountains called Evolution Canyons‚ which are all located between a southern facing slope (SFS) and a northern facing slope (NFS). What’s particularly interesting about these locations is that despite the two slopes being on opposite sides of a small canyon‚ they exhibit extremely contrasting conditions. The SFS receives multiple times the UV radiation from the sun
