December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms

1. Why do flowers have such a pleasant scent? What would be the practical reason? The practical reason for flowers having such a pleasant scent is to attract birds and insects such as bees. By attracting them to the flower‚ the bird or insect will be more likely to spread the pollen of the flower around‚ allowing for reproduction of that flower. 2. What is the reason behind evolutionary adaptation of flowers into bright colors? The reason behind the evolutionary adaptation of flowers

Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

Complete the following questions and submit via Blackboard 1. List two events which occur during prophase of mitosis: 1. An aster is formed by fibers radiating from the centrioles of the cell. 2. Chromosomes are formed when the chromatin threads coil and then condense‚ and these chromosomes are two identical chromatids bound together by a centromere. 2. What is the main occurrence involving the chromosomes during

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

* Fungi are Eukaryotic‚ mainly multi cellular organisms includes molds and mushrooms * fungi lack chlorophyll * they are heterotrophic and cell walls contain chitin * more closely related to animals * supergroup Unikonta categorized as opisthokonts bc of single posterior flagellum * heterotrophs‚ secrete enzymes which digest food outside the body‚ the broken down food is then absorbed by hyphae * 3 types of fungi * decomposer fungi‚ absorb nutrients

Transport of vesicles facilitated by kinesin and the effects of mutations in nerve transmission in Caenorhabditis elegans Introduction A nerve cell is made up of three main structures: the soma‚ the axon and the synapse. When a nerve cell receives a signal‚ a protein called kinesin travels anterograde along the axon and guides the synaptic vesicles until it reaches the synapse. This triggers the release of the neurotransmitters stored within the vesicles. Once released‚ the neurotransmitters then

Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.
