body heat. (What Attracts Gnats?) For example‚ soccer games ending late in the evening‚ and sweat pouring from everybody gnats tend to swarm up around most of the people out on the field. Gnats and fruit flies are very similar. The only difference between the two‚ is that gnats form big groups outdoors‚ while fruit flies are mostly found indoors. Either way they’re living‚ they’re both extremely annoying. There are many different types of gnats‚ which are Fungus Gnats‚ Drain Flies‚ Midges‚ Sand

Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

Cell Biology Lab - Homework 1 Due to the week of Oct. 6-10th This is NOT a lab group project. Do the work individually. You may use any source other than your fellow students. Show your work‚ use your own words and cite all references. 1. (20 points) The HeLa S3 cancer cell line is considered to be “continuous” due to acquired mutations that enable the cells to evade senescence. This property is one of several hallmark characteristics of cancer cell lines. Describe three hallmark characteristics

7 July 2013 Brain regions where ideas become contagious identified by Will Parker How do ideas spread? Why do some videos go viral? UCLA scientists have taken a first step toward answering these questions by identifying the brain regions associated with the successful spread of ideas. The research‚ reported in the journal Psychological Science‚ has broad implications and could lead to more persuasive advertisements and better ways for teachers to communicate with students. The study suggests

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill

The Variation of Yeast Cells When Adding an Antibiotic Biology 1401- A October 21‚ 2013 Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was
