rainforest can provide jobs food and water. Rain is very common in the rainforest because of its high humidity rate. Rainforests have a humidity rate of 77% to 88% all year long. The rain forest is an environment that is rainy and humid. The rain forest only has one season because it’s weather and temperature never change. The temperature never changes because of the high humidity rate and waters thermal resistance. The rain forest has direct sunlight that provides light and heat but indirect

Does pornography affect your life? It might if you are part of the “28‚258 people surfing porn” (Tech Crunch) that happens every one second. According to Gaddis (2009)‚ Pornography has existed for a long period of time although it has not been a serious problem that causes major issues until now in the 21 century. The pornography business has become a multibillion dollar industry. Access to pornography has become so easy to access that you do not have to even drive to your local shop for a playboy

speed up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier to reaction. This is called the activation energy. Even though enzymes can alter the rate of reaction

To what extent does heat exposure affect an athlete? Heat exposure is a factor that is essential to be considered by athletes to maximise performance level. Researchers have investigated that excessive heat exposure or exercise hyperthermia has detrimental effects on exercise physiology. Little is understood regarding the effects of hyperthermia and how heat exposure affects the body. Localised heat studies using water immersion to increase muscle temperature have been conducted to investigate the

It is used in prescription and over the counter drugs. It increases blood pressure‚ mental alertness‚ and gastrointestinal motility. Cardiovascular development with caffeine and other small molecules can be studied relatively easy using zebrafish. The cardiovascular system is complete in two days after fertilization

Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. Introduction

source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless‚ flammable liquid that is categorized under bio-fuel. Brazil is the largest suppler and consumer of ethanol in the world. Ethanol functions
