PART B YOU WILL NOW DESIGN AN EXPERIMENT TO STUDY THE EFFECT OF A FACTOR AFFECTING VITAMIN C IN FRUIT JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit

passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1 Acetylcholine is an organic chemical that functions in the brain and body as a neurotransmitter it is an ester of acetic acid

construction material and magnetic materials fields. Temperature of ball mill has an important impact on the quality of products. To understand the issue of temperature control of ball mill can better finish grinding. Temperature of ball mill is big issue. Appropriate temperature must be set in production. Temperature not only affects the properties of ball mill material but also the grinding performance of grinding materials. The normal temperature of ball mill is high and there are many reasons

Title of Experiment: The Effect of Temperature on the Hatching Success of Brine Shrimps. Abstract In this experiment‚ 40 brine shrimp eggs are put into a test tube containing salt water at different temperature such as 25°C and 35°C respectively. The eggs are left from two days to hatch. After two days‚ the number of eggs successfully hatched are observed and counted. Introduction Brine shrimp is the common name for a primordial crustacean that reaches less than 1.3 cm in length and is usually

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

Biochemistry CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature up to 50oC speeds

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

PHYTOGRAPHY: THE ROOT Name: Carl G. Buscato 3‚ 2012 Score: _____ Section: K28 Date: December I. INTRODUCTION The roots of most plants are found underground although there are plants that have their roots suspended in the air as in orchids. The entire mass of roots is called the root system. The root arises from the radical which later becomes the primary root. Branches that develop from the primary roots are called secondary roots are the tertiary roots. The primary function of the root is absorption

plasma membrane of a cell is extremely important to the transportation of substances into and out of the cell. The outer membrane of a cell is made up of lipids and proteins. Most of the lipids in plasma membranes are phospholipids. The phospholipids have a hydrophilic head and two hydrophobic tails. When engulfed in water‚ they arrange themselves such that all the hydrophobic tails clump together‚ surrounded by the hydrophilic heads‚ protecting the tails from the exposure to the water. In cells‚ which
