For example; I think conquering my addiction will be a good thing because that is one less thing to worry about in my life. But leaving my comfort zone is hard because I don’t like to change myself. Let’s see how my experience goes. Leaving my comfort zone experience is affected

1. INTRODUCTION OF POTATO CHIPS: Potato chips also called as potato crisps were invented in the year 1853 by Native American George Crum. The story behind the invention goes like this. George was employed as a chef at an elegant resort in Saratoga Springs‚ New York. One dinner guest felt George’s French fries too thick for his liking and rejected the order. In order to rile the guest Crum decided to make fries too thin and crisp. But seeing the browned‚ paper thin fries the guest

of osmosis of tap water of Solanum tuberosum L. Solanum tuberosum L.‚ also known as potato‚ was the selected plant to be tested because it was easy to measure the percentage change in mass due to the osmosis of water into the tissue. RESEARCH QUESTION How does the surface area to volume ratio of potato tissue (Solanum tuberosum L.) affect the rate of osmosis of tap water? HYPOTHESIS The smallest cube of potato (1x1x1)‚ having a higher surface area to volume ratio‚ will have the fastest rate of

Paranthropus robustus was named as such not because of their size but because of their large teeth and face size. In actuality‚ males were an average 3 ft 9 in tall‚ one hundred nineteen pounds‚ and females on average were approximately 3 ft 3 in‚ eighty-eight pounds (Smithsonian’s National Museum of Natural History‚ 2015). The name robustus comes from the fact that they had very large teeth with thick enamel and focused their chewing in the back of the jaw. Large zygomatic arches gave way for large

substances in the cells of a potato using Osmosis. I predict that the potato in the higher concentration of salt solution will lose an increasingly high amount of weight. I think this because the higher the concentration in salt‚ the more water particles will move through the potato cell’s semi-permeable membranes to try and balance the salt concentration. For example‚ if you placed a larger piece of potato into a beaker of an almost 100% salt solution; the potato would completely shrivel up because

Conclusion The research question that I asked myself before the experiment was “What is the osmotic potential of potato?” The answer I got after the experiment was that the osmotic potential of potato is very high because this experiment exactly showed what happened when there is Osmosis present and the following information will prove it. Our results greatly showed that there has been osmosis present. Osmosis is the diffusion of water through a partially permeable membrane from a region of lower
