“The History of Water on Mars” Essay Water is a very abundant resource in our solar system. You can find water attached to most of the colder and farther planets. When I speak of water though‚ I mean ice water. Not the silky drink you have every day‚ but the very high-pressure sealed water that is usually found below the sediment and crust. “But shouldn’t that be where liquid water comes from?” is what most ask‚ and sometimes the answer is yes‚ but there are many situations that vary. Just like

the current water shortage on Oahu. For the purpose of this paper‚ our group has chosen to discuss what we believe to be the top three most feasible technological solutions. In order of current usability they are; 1. Water recycling 2. Desalination 3. OTEC (Ocean Thermal Energy Conversion) Water Recycling Water recycling here on Oahu is an important part of ensuring a sustainable water supply for future generations. Through the natural water cycle‚ the earth has recycled and reused water for millions

Peer pressure‚ it has been questioned alot. Students are pressured to do good in school‚ they are also pressured by their family. So‚ children are pressured to grow up too fast‚ by many ways; Such as‚ pushed by their parents to get good grades‚ teens get pressured by a tradition to a college that was carried onto the families by generation and the pressures to get a job.

Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and they can then be moved

Purpose: How will salt and plain water affect plant cells? Hypothesis Clear water: If you place carrots and celery in plain water they will become flaccid and then eventually start to loose its colour and pieces of the celery or carrots will fall off. I know this because the vegetables will continue absorbing water putting the vegetable in a hypotonic solution. Pieces of the vegetable could break off because the cells are not getting what they need. The cells need to create glucose and oxygen

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution
