Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest

The different cell membrane transport mechanisms The cell membrane is referred to as a ‘fluid mosaic model’ because the protein part within the cell membrane used to be though of as an even layer spread over the outside and the inside of the phospholipid. Now we are starting to think that it is spread unevenly‚ more like a mosaic than a layer. The phospholipid part of the cell membrane is fluid; this means that its molecules are constantly moving about. Through the molecules constantly moving

Conclusion to Motion Lab Kerreon Wright 3rd Period Ms. Gislason The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible

Conclusion to HIV Aids Media has a powerful role to play in educating the world. It was years ago‚ that Acquired Immune Deficiency Syndrome‚ the disease now recognized all over the world as AIDS‚ was first detected and recorded in Asia. Over the past two decades‚ the infection rate has grown rapidly in Asia‚ which is now second number to Africa in the number of HIV positive people. In Pakistan‚ HIV and AIDS was first detected in 1986 and according to UNAIDS estimates‚ this country now has over

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

Analysis and Interpretation Trends of the data: With the cross-sectional area on the whole it seems to increase as the river progresses‚ with Site 1 being 9.23 and Site 5 being 18.13. However Site 4 has a higher figure than Site 5‚ yet this was due to the fact that we could only use part of Site 4‚ as one half of the river was completely dry‚ so the results from that site are likely to be an anomaly. Looking at the Bedload in the bar graphs it is clear that with the pebble roundness the pebbles

Introduction and Conclusion Ignacio Reyes COM 220 October 05‚ 2012 Mary Mc Williams I would start off my paper writing about different types of drugs and the effects it has on society these days. The drugs‚ the side effects‚ and how these affect our loved ones. From experience I can say that using drugs and going the wrong way will always bring problems to the table‚ emotionally and financially. I will also be talking about drugs and where they come from‚ who the bad people

. Chemistry helps sustain bacteria by protecting the bacteria from outside organisms in the environment out and keeping the bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment
