The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

COLORS When the eye sees a color it is immediately excited and it is its nature‚ spontaneously and of necessity‚ at once to produce another‚ which with the original color‚ comprehends the whole chromatic scale. Goethe‚ Theory of Colors COLOR PRINCIPLES Hue‚ Intensity & Value HUE Hue is the base color for example‚ pure red or blue. INTENSITY Intensity (also called saturation) is the amount of color. The lower the saturation‚ the more gray the color is. VALUE

Purpose Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries‚ even when the surrounding temperature varies and is of higher or lower temperature than what is normal. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body so as to maintain a relatively constant core temperature of approximately 36.7 degrees celsius. If this was unable to take place the body may not be able to functions properly and it could result

Jars were filled with a 100ml of federalized water‚ and a mark at the 100ml was made as indication to ensure the correct amount of water was given if the jars needed to be topped up. With a Q-tip‚ 10 green Lemna leaves with growing roots were placed into each of the ten designated jars. The five room temperature jars were placed into

December 1‚ 2010 Classical Design versus Modern Design There are many different design styles. Some are very similar‚ such as traditional and classical and some are complete opposites‚ such as classical and modern. These two design styles are opposite in just about every way. In the modern design style the focus is on simplicity and asymmetry whereas in the classical design style the focus is on balance and symmetry. In the modern design style there is a feeling of less is more.

The Effect of Temperature on Blow-fly Larvae INTRODUCTION Calliphoridae- comonly known as a blowfly‚ are living organisms which usually are the first insects to colonise a body after death. The blowfly larvae are very useful in forensic entomology. The oldest larvae give an approximate time of death of body. Family: Calliphoridae Order: Diptera Name: Calliphora vicina Aim: To check the influence of temperature of environment on living functions and activity of Blow-fly larvae.

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved
