Chapter I Introduction A. Background of Study | Termite is a common name for numerous species of social insects that can damage wooden structures such as furniture or houses. Of about 2000 known species‚ most are distributed in tropical countries and some inhabit the temperate regions of North and South America; two have become established in southern Europe. Termites are known also as white ants‚ a misnomer based on superficial similarities in the appearance and habits of these

In Alfred Wallace’s article‚ The War in Cardboard and Ink: Fifty Years of Civil War Board Games‚ he provides insight and examples of how war games have advanced since they were first released. Details supporting the advancement include; video games‚ addressing conflicts‚ audience‚ popularity‚ materials‚ and art cover. Throughout the article‚ Wallace provides four ways war games are played; board games‚ miniature games‚ solitaire games‚ and video games. Although Wallace also claims that‚ video games

insecticidal potential of chili pepper leaf extract against termites. The garden vegetables pepper‚ Capsicum annuurn‚ of the Solanaceae‚ or nightshade family‚ is grown throughout the world and produces not only the green‚ bell-shaped‚ sweet peppers that are common garden varieties‚ but also the hot peppers used for such spices as paprika‚ chili‚ and cayenne. Most cultivated peppers belong to one of two major groups. The Grossum group yields the globose‚ mild-flavored sweet-peppers and the pimiento

1985‚ Kumar et al. 1994‚ Jayanetti & Follett‚ 1998)‚ the young bamboo culms in particular or that has been insufficiently treated with preservatives usually deteriorate rapidly by the action of a mixed population of soil microorganisms and termites. Fungi and termites may still colonize even to those bamboo regarded as adequately treated with preservative. The decay and the attack rates on these bamboo may be slower‚ and the patterns of fungal colonization may also differ from untreated or less adequately

Stroop was interested in the effects of interference and he tested it using colors‚ blocks and symbols to do this. Stroop used names of colors printed in incongruent ink‚ the same color ink‚ and in black ink to see if there was an effect that could show interference. He wanted to know how interference could be effected by stimuli like color and symbols. By looking at other research that was done before he dove into his studies on interference‚ he was able to gain insight on the subject. One of them

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Environmental Health Sciences Center Community Outreach & Education Program CHROMATOGRAPHY (Adapted from: Forensic Science Activities. University of Colorado Boulder Hughes Initiative. .) DESCRIPTION: Students will use paper chromatography to separate ink molecules and identify the pen used on an unknown sample of handwriting. Students will graph and analyze data they collect using paper chromatography. PURPOSE/GOAL: Students will be able to: • Gain understanding of the purpose of chromatography. • Measure

Chromatography Lab Questions Pre-Lab Questions 1. A pencil is used rather than a pen to mark the “starting line” in step two because a pen or marker while be used to place a small dot of ink in the center of the X that is made with a pencil. 2. Capillary action is filling of pores in a solid with a liquid. Capillary action is caused by spotting or absorption and is allowed to seep or flow through. 3. The type of pen that will probably give better separation in this paper chromatography

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal
