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

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

    Diffusion is important because it is how particles are moved into a cell and out. Diffusion is the movement of a particle from an area of higher concentration to an area of lower concentration (Reasoner 2011). Passive diffusion and facilitated diffusion are the two major types of diffusions. Passive diffusion, also known as simple diffusion, is when particles move freely through the lipid bilayer of the plasma membrane (Tortora and Derrickson 2014). Facilitated diffusion is when and integral membrane helps the particles move across the membrane because the solutes are too highly charged to move through the plasma membrane (Tortora and Derrickson 2014).…

    Therefore, you would characters the cell by first looking at the osmolarities and then base its tonicity on that. An aqueous solution when compared to a cell could be described as hyperosmotic: where the solution has a greater concentration of solutes than the other solution; hypo-osmotic: where the solution has a lesser concentration of solutes than the other solution; and isosmotic: where the two solutions have the same concentration of solutes. For example, when the environment of a cell is a Salt marsh, depending on its location the salt concentrations will differ and the cell will go through an osmotic regulation. Therefore, animals in different environments would have to adapt its cells to its environment differently than others would in different environments. When refereeing to tonicity, if an animal cell is in a hyperosmotic solution, the environment is be referred to as hypertonic…

    Diffusion is the movement of atoms or molecules from an area of high concentration to an area of low concentration down a concentration gradient. Osmosis is the spontaneous movement of water particles from a region of high concentration to a region of low concentration through a selectively permeable membrane. What is osmotic pressure? Osmotic Pressure is the minimum amount of pressure needed to be applied to a solution to prevent the inward flow of water across a selectively permeable membrane. Identify and discuss various buffer systems found in the body.…

    This effect is generally observed at low ionic interactions. The solubility of a protein is a complexed function of the physiochemical nature of the protein, pH, temperature, and the concentration of the salt used. It is also dependent on whether the salt is kosmotropic (stabilizes water) the proteins usually increases slightly (salting in). But at high concentrations of salt, the solubility of the proteins drop sharply . PRINCIPLE : Proteins are surrounded by the salt counterians (ions of opposite net charge) and this screening results in decreasing electrostatic free energy of the protein and increasing the activity of the solvent, which in turn, leads to increasing solubility.…

    -If a starch solution would be used, the change in the final mass would be more drastic. More molecules would have been able to enter the solution in the dialysis bag easier, therefore, increasing the final mass of the solution. 3.

    Introduction The cell membrane provides a boundary between the intracellular environment and the extracellular environment. The membrane is selectively permeable only allowing some substances to pass through while some can’t. The cell membrane consists of two phospholipid bilayers. Each layer has an electrically charged, hydrophilic head, while the tail is an uncharged hydrophobic. The electrically charged head of these layers face toward the water as the uncharged tails face each other.…

    Various particles move easily and “freely through the lipid bilayer of the plasma membrane”. (Tortora and Derrickson 2014) This particular passive process is called Simple Diffusion. Simple Diffusion allow for a substance to “move down its concentration gradient”. (Brown 2011) Other types of process include Channel- Mediated Facilitated Diffusion and Carrier-Mediated Facilited Diffusion. This process is focused on solutes with different charges or polarity.…

    The inner membrane contains enzymes to help with aerobic respiration, and is folded to increase the surface area therefore increasing the rate of reaction for the production of ATP. The chloroplasts have three membranes: an inner and outer membrane and thylakoids stacked into grana. The inner and outer membrane holds the stroma, which makes up most of the mass of the organelle. The outer membrane is partially permeable to allow small molecules or ions to pass through. Chlorophyll is stored in the thylakoids for photosynthesis.…

    Carbohydrates are the molecules that are moved across the membrane during this mechanism. This process requires energy (ATP). Passive transport does not require energy to move molecules and other substances across the membrane. Proteins are the molecules, during this mechanism, that are transported across the membrane. Osmosis is the diffusion of free water across the semi-permeable membrane, whether it is artificial or cellular, so that both sides are equally balanced.…

    NADH and FADH2 can be used in the electron transport chain to create ATP by oxidative phosphorylation. During oxidative phosphorylation which takes place in the inner mitochondrial membrane, NADH and FADH2 are used to pump hydrogen ions across the membrane against proton gradients (chemiosmosis process). A protein complex, ATP synthase which is in the membrane and enables protons to pass in different directions, enables ATP production when the protons move down the gradient. It takes ATP to pump a proton against a gradient and since protons have already been pumped against the gradient (done by…
