1. Describe the trends/outcomes with reference to that shown in the Results.
The results, table and graph, show that brown, jasmine and white rice all absorbed different amounts of water. The average amount of water absorbed after 60 minutes by white rice was 94.3 mL’s whereas jasmine rice absorbed and average of 66.3 mL’s of water after 60 minutes and brown rice absorbed the smallest amount of water of all three with an average of 49.7 mL’s after 60 minutes. They all gradually increased during the 60 minutes of the experiment but as the line graph and table shows, the highest amount of water was absorbed in the first 10 minutes for all three types of rices.
2. Was the outcome different or same as your hypothesis? Explain why or why not.
Yes, the outcome was the same as my hypothesis which stated “white rice absorbs the most water”. White rice absorbs the most water because according to it has been stripped of the husk, germ and bran. This is for better flavour, texture, appearance and so it lasts longer in storage but also results in better absorbency as it is quite soft compared ...
In the experiment “ Talking to plants “ from Mythbusters, potential problems include the use of greenhouses with no sound insulation, a non-homogeneous location and the use of only one specie to infer on a population. In another scientific study, researchers chose to use “ a noiseless growth chamber to prevent any effects from extraneous noise “ and the use “ growth chambers under continuous light at 28 c and 65-75% relative humidity “ in order to maintain a homogeneous location for all plants during the experiment (Jeong et al., 2008) . This helped further explain the findings because with the use of noiseless chambers you can assure that the only noise that the plant was receiving was the one given in the treatment and a valid conclusion
For part one of the experiment, my team asked the question of which cell fraction of the measured pea seedlings will have a higher ratio of chloroplasts? My group tested for the activity of chloroplasts with three different pairs of cell fractions by two conditions of light and dark in three readings. The first two cell fractions, pellet one and two (P1, P2), are the hard sediments found at the bottom of a tube after it has been centrifuged (which are specimen, like the mitochondria and chloroplast, that are isolated from the rest) (Leicht and McAllister, 2016). The last cell fraction used was the supernatant two (S2), which is just the free liquid surrounding the pellet after the centrifuging of P2 (Leicht and McAllister, 2016). To test for this, DCIP (a chloroplast isolation buffer) was used to
I believe that the first unknown solution is made up of molecular compounds. This is because the solution had very little conductivity, meaning there was not an equal amount of ions broken down in the solution. The solution had no scattering, which means the molecular compounds were fully dissolved in their solvent, which was not water. When tap water was added to solution 1, the color changed from green to blue. If water was the original solvent, we would not see this color change. The absorption spectrum follows most of what the color green would absorb on its own: red, blue, and purple wavelengths. However, there was some absorption of the green wavelength. The first solution has the highest overall absorbance
Osmosis is a type of diffusion which is only applied on water and is a passive process which does not require an input of energy from the cell; this is because materials are moving with the concentration gradient. Osmosis is a process that occurs at a cellular level, which entails the spontaneous net movement of water through a selectively permeable membrane, from a region of high to low water concentration, in order to equalise the level of water in each region. This form of diffusion takes place when the molecules in a high concentration are too large to move through the membrane. The term semi-permeable or selectively permeable means that some substances can easily pass through the cell membrane, whereas others cannot. The significance of osmosis to cells is great, since it is the osmotic pressure that maintains the shape of an animal cell and provides support in the plant cells. Many factors affect the rate of osmosis including size of particles and temperature however in this particular experiment the factor investigated is the concentration of sodium chloride. Tubes of potatoes will be used to demonstrate the fact...
The lignin in plants is less hydrophilic compare to cellulose a hemicellulose, it present the absorption of water.
Most of water consumed in China is not rationally used. The cause which intensifies the water shortage in China is water inefficient use. For instance, 65%-70% of Chinese water usage is spent on agricultural needs, but more than half of this amount evaporates percolates and loses (Roberts 2009). Besides, majority of another 20%-25% which is occupied by China’s industry is not recycled (Brown 2008a, 16; Roberts 2009). Obviously, improving water distribution technologies and management quality can be one of the options to reduce the water scarcity in China. There are many different methods of improving the water distribution efficiency. Firstly, irrigation technologies should be improved. Farmers in China may use drip and shrink irrigation methods instead of traditional “surface” ones such as furrow and flood irrigation. Drip irrigation method is used mostly in arid and semi-arid zones and it increases the efficiency of irrigation by transporting the water directly to the roots of irrigated plant. The emitters sprinkle the soil under the roots with water which is introduced to the plant by pipes, diminishing water evaporation, deep percolation and leak. In contrast, fur...

Observations: The experiment shows that the lower the concentration of the sugar solution, in the Petri dish, the mass of the potato increased.
I chose to volunteer at Rice Care Center and Therapy Suites in Willmar, Minnesota. I chose to volunteer here because, I work in Therapy Suites and primarily interact with short-term patients. Since patients are there for rehabilitation, I do not get a lot of time to build relationship as they are busy with physical and occupational therapy and often have company throughout the day. During my time volunteering, I decided to go to the long-term units, Cushman Cottage and Sophia House, and spend time with the residents there. Another reason I decided to volunteer here is because not every resident gets company or a phone call for days, maybe even weeks at a time. I strongly believe everyone, regardless of age and status, craves interaction with another human being.
In the essay " Rice for Thanksgiving " by Jocelyn Fong who is a full american, partial asian young girl is a young girl who admires her untraditional thanksgiving, and meaning. Fong loves thanksgiving, due to her Grand mothers special dish " Rice and Gravy " as said in the essay Her Grandmother always celebrated the American way, She even never got around to teaching Fong's father their native language. " I believe in rice and gravy, I am half Asian and completely American. " by Fong saying that, she completely accepts the mix she is by referring to the mix of food that is a tradition. You should celebrate holidays the way it makes you happy, with your very own culture regardless the fact if it is different.
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
... els of sucrose solution to distilled water (see molarity table above) and I placed each of the mixtures into the correct beakers. 5. Then I weighed all the potato chips on an electronic balance (see results) and recorded the results. 6. I placed 5 pieces of potato into each beaker and left them for approx 36 hrs. 7. After this time I drained out the solutions from the beakers and I carefully placed them in order of molarity on a paper towel. 8. I dried the potato chips gently and then weighed each potato piece and recorded the results. 9. As I had extra time I made a second experiment and also recorded those Results: Molarity (M) Starting Weight (g) (Results 1) Final Weight (g) (Results 1) Percentage Change (%) (Results 1) Start Weight (g) (Results 2) Final Weight (g) (Results 2) Percentage Change (%) (Results 2) These values clearly support my prediction, and even though there are some anomalous results, there is an overall negative trend across the whole set of results, proving them accurate. Analysis of Results: The sucrose concentration of the solution into which the potato tissue is placed affects to what degree it grows or shrinks. As you can see from the graph the results show a clear negative correlation, a very obvious inversely proportional trend. From this a conclusion can be drawn. When the water concentration is high, the potato gains water, as seen by the 0.0 molarity solution. When the water concentration is low, the potato loses weight and therefore decreases in mass, as seen in the 1.0 concentration solution. This proves my hypothesis correct. The results were quite widely ranged, as seen on the graph, wit ......

After finishing the trials, our group subtracted the mass of the glassware without water from the mass of the glassware with water in order to find the mass of the water in grams. Then, we divided the mass of the water by the density(g/cm^3) of the water in order to find the volume (mL). An example calculation from the 5.00mL pipet is: (4.9285mL+4.8839mL+4.9367mL+4.9265mL+4.9134mL)/5 = 4.9178. In most cases, the temperature of the water was around 23 degrees celsius, making the density about .998408 g/cm^3 for many of the trials. The densities we used were found online. The next calculations we performed were to determine the average volume of the water in each person’s five trials by adding up all of the volumes(mL) and dividing that number by five. Using the average volume, we then calculated the

My social experiment, took way too much thought to complete. I could not think about what I should do for this project until about noon on that beautiful Sunday. I invited a couple of friends to go with me to Walmart, but I was unsuccessful and I only got one friend to accompany me. Even so, we had fun.
