How Cold Affects The Body B Y: G E N E S I S P O N C E How Cold Affects The Body The body tries to maintain body temperature by vasoconstriction and shivering. Shivering is the body’s main involuntary defense against the cold producing body heat by forcing muscles to contract and relax rapidly. Vasoconstriction is the tightening of blood vessels Vasoconstriction occurs in the uncovered skin when it is exposed to cold temperatures. The reduced blood flow in the skin conserves body heat

increase the concentration and so the rate of photosynthesis of the crops. The additional cost of the carbon dioxide is worth it because of the increased yield‚ which means that there will be more product made. (http://www.passmyexams.co.uk/GCSE/biology/factors-affecting-rate-of-photosynthesis.html) Some companies may use this idea for environmental use. Instead of pumping the wasted carbon dioxide into the atmosphere as a pollutant they redirect it into big greenhouses where plants such as tomatoes

Experiment 9 : The effect of substrate concentration on enzyme activity Objective To find out the relationship between the substrate concentration and the rate of reaction by determining the number of bubbles produce Hydrogen peroxide (H2O2) is a by-product of biochemical metabolism. An accumulation of hydrogen peroxide can be deadly‚ so it has to be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. The chemical

Properties of Different Bonds An ionic compound forms from a nonmetal and metal element. A covalent compound is formed by two non metal elements. A metallic compound is formed by two metal elements. Metallic compounds have generally high melting points‚ are loose and flexible with their electrons‚ conduct electricity well‚ and have low solubility in water. Ionic compounds are generally crystals‚ have a high melting point‚ and usually have high solubility in water and conduct electricity well when

How The Media Affects Society The media is undoubtedly a significant and influential aspect in modern day society. As a means of communication in a world very much advanced in technology‚ the media touches all types of people through various forms such as the radio‚ newspapers‚ televisions etc. The question remains: what information is left unbiased and untarnished? The people within society must sort through the many bits of information fed to them and unfortunately‚ in most cases‚ all bits

Animal Diversity The number of animal varieties familiar to us is vast as the animal world is diverse. Each distinct variety or type of animals is recognized by scientist as a species. Animals of most species are free-living forms but of others are parasitic in bodies of other animals or even plants. According to their habitats animals are divided into the following types Aquatic animals :- They live in water . Animals living in sea water are called marine & those live in river‚ponds‚streams

How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately
