1) Richard is remodeling his room. He wants to know which tile is the strongest and that will last the longest. To test the experiment, Richard will drop a 1lb rock, 2lb rock and a 6lb bowling ball. Whichever tile that breaks he will not use, and the most durable one, he will use. The independent variable is the durability and the dependent variable is the weight Richard will be putting one, since its changing.
He starts with Tile Type One he first drop the 1lb rock, there is no visible crack. Secondly, he drops the 2lb rock, a big crack goes through the middle. Lastly, he drop the 6lb bowling ball and the tile completely shatters. Richard now takes Tile Type Two and puts it up for the test. He drops the 1lb rock on the tile, the rock had …show more content…
This all works because in the membrane there are different membrane proteins that use ATP to work. One way is active transport. Active transport is when, for example, sodium, will pass though the protein channel and go to wherever there is a higher concentration of sodium. If there is more sodium in the cell, the sodium will want to go into the cell, because there is a higher concentration of sodium. Another way is called osmosis. This is when a semi-permeable liquid or solid goes in or out of the cell. This way also takes ATP to work. For example, water, if there a more sodium outside the cell, the water will move there because there is more substances on the other side. The second to last way is called diffusion. This is when there is a substance in water, say food coloring, the coloring will make equilibrium with the water. The coloring will evenly spread through the water, making it evenly distributed. The last way a substance moves in or out of a cell’s membrane is called facilitated diffusion. Facilitated diffusion is the spontaneous movement of a solute that goes into the channel protein. A solute goes into the pore of the channel, then the channel helps diffusion process and does not require energy. The molecule is released in the far side of the
