The Insecticidal Potential of Chili Pepper Leaf Extract Against Termites Abstract. The goal of this research is to determine the insecticidal effects of chili pepper leaf extract on termites. Chili pepper leaves were collected then air-dried and oven-dried until brittle. The leaves were then pulverized and milled using the Willey mill. After this‚ the powdered leaves were boiled in water and filtered. After the preparation of the extract‚ termites were gathered in two containers. One of the containers

Biochemistry is the chemistry of biological systems. The practical component of biochemistry is aimed at developing your interest in and understanding modern biochemical and molecular biological experimentation. The techniques learnt in the biochemistry lab will be applicable to all life sciences. THE OBJECTIVES OF THE BIOCHEMISTRY LABORATORY INCLUDE: (1) Learning the theory behind the techniques and biochemical pathways (2) Learning the physical skills and techniques of modern experimental biochemistry

Multimedia Graphic Bell Labs: A Hive of Invention But we idealize America’s present culture of innovation too much. In fact‚ our trailblazing digital firms may not be the hothouse environments for creativity we might think. I find myself arriving at these doubts after spending five years looking at the innovative process at Bell Labs‚ the onetime research and development organization of the country’s formerly monopolistic telephone company‚ AT&T. Why study Bell Labs? It offers a number of lessons

Jeanine Campa Biology 101 10/20/2010 Ecology-Interspecific Interactions Lab Intro: Ecology is the study of how organisms interact within their environment. Every species interacts with its surroundings‚ whether it’s within their populations‚ community‚ ecosystem‚ etc. In this lab‚ we will be comparing two different species and how they grow alone as well as together‚ in the same environment. More specifically‚ in this lab‚ we will be dealing with one of the most important ideas in ecology‚ the

Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this lab a colorimeter is used to find the

In each station there was a positive and a negative control. If the substance was the same as the negative control then it was negative. If the substance was the same as the positive control than the substance is positive. In the first lab we did the Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then
