were able to build immunity to them‚ whereas the diseases they brought to the new world killed upwards of 90% of the native population. One plant from the Columbian Exchange was the potato. Originally from South America the crop came to the old world and became extremely important. Marie Antoinette turned the potato plant’s flowers into a fashion statement‚ and wore them as encouragement for French people to eat potatoes. They became the most important food source to the people of Ireland. When

When potatoes are harvested and shipped with other ingredients‚ a great deal of fuel is exhausted‚ creating smog or air pollution. In addition‚ freezing the potato slices uses ten times more electrical energy than fresh food. This process worsens the greenhouse effect because hydro fluorocarbon coolant‚ which is used for freezing potato‚ rises up into the stratosphere and traps heat. Processing potatoes is another factor in pollution of natural water. Because two thirds of a gallon of wastewater

Diffusion and Osmosis in an egg Low concentration 1.1 Diffusion is the process of molecules spreading from areas of high concentration to areas of low concentration. High concentration 1.1 Osmosis is the diffusion of water molecules through a semi-permeable membrane from the area of low concentration of solute to the area of high concentration of solute. 1.2 Diffusion is important to living cells because it’s the way they take in materials from the environment‚ and they also prevent themselves

sales floor‚ and eventually‚ your hand. In fact‚ potato chips contain two cancer-causing materials; Butylated hydroxyanisole (BHA) and butylated hydrozyttoluene BHT. They are used to keep oils in foods from oxidizing and becoming rancid. Oxidation affects the flavor‚ color‚ and odor of foods and also reduces some nutrients (Berkley Wellness). These chemicals are oxidants‚ when in the human body; they turn into cancer-causing reactive compounds. Potato chips aren’t the only foods that contain these
