wrote “It is remarkable that the same plant should be found on the sterile mountains of Central Chile‚ where a drop of rain does not fall for more than six months‚ and within the damp forests of the southern islands” (Chapaman). He was speaking of the potato‚ and its ability to adapt to a variety of climates‚ from the semiarid to the tropical wet. Potatoes also have high nutritional value. They supply every vitamin and mineral that a body needs except for vitamin A‚ vitamin D‚ and calcium (Chapaman).

commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted and towards a stimulus that is favored. Different stimuli which can cause taxis to occur are light‚ sound‚ moisture‚ heat‚ or chemicals. To narrow the possibilities‚ this specific trial will test whether potato bugs favor fresh water environments

SCM3006 Operations and Supply Chain Management Group Project Product: Baked Potato 1. Introduction 1.0 Introduce Baked Potato A baked potato is sometimes called a jacket potato in the United Kingdom. The baked potato has been popular in the UK and French for many years. In the mid-19th century‚ jacket potatoes were sold on the streets by hawkers during the autumn and winter months. In London‚ it was estimated that some 10 tons of baked potatoes were sold each day by this

functions unable to work properly. The focus of this study is to measure the effects of external factors of temperature‚ pH and enzyme concentration levels and how it effects the catalyst reaction times of catecholase and peroxidase enzymes using potato extract. A review on how enzymes react under certain external conditions gave a good foundation to base this experiments hypothesis when looking at concentration of enzymes‚ temperature and pH levels.

gradient. Hypothesis: Will a high concentration of salt solution affect the mass of a potato chip? Variables Controlled variables: -The sizes of the potato chips. Bigger size of potato chips will weigh heavier and the smaller potato chips will weigh lighter‚ if we don’t use the same size of potato chips throughout the experiment‚ we won’t get an ideal result‚ there will be great differences between the mass of potato chips. -The duration of experiment. The duration of the experiment must be the same

Diffusion of Ammonium hydroxide with red litmus paper Definition of diffusion 1. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out. 2 Diagram. 3. During the diffusion tube experiment I noted that firstly ammonium hydroxide was placed on to a piece of cotton wool. The cotton wool (with the ammonium hydroxide) was then placed in to a diffusion tube containing around 10 pieces of curled red

weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through osmosis therefore there will be no percentage of weight change in potato cubes 2) The

pressure exerted on either side of the semi-permeable membrane. A potato (Solanum Tuberosum) contains 92% water‚ which is an osmotically active component. The precise osmotic potential of sweet potatoes is however unknown. The osmotic potential of sucrose is know to be at 20 oC‚ the osmotic potential of sucrose is 2.436 MPa2. The rate of osmosis will be calculated by measuring the percentage change in mass of a piece of potato‚ that has been submerged in a specific concentration of sucrose over
