The line of best fit gives the respiration rate of day-old seedlings as the concentration of NaCl they are exposed to increases. As NaCl Concentration increases the rate of cellular respiration decreases by .108 ppm CO2/g per second. This overall decrease throughout the data further supports our hypothesis. Discusion: The data collected in the experiment does support our hypothesis. By examining the data as a whole a trend of decreased cellular respiration in seedlings soaked in solutions with increased NaCl concentrations.
The solution that have a molarity of 0, cause the object to be isotonic. If the temperature of the glucose solutions that had different molarities increased, the reaction of the potatoes weight would have happened faster. And vice versa, if the temperature of the glucose solutions that had different molarities decreased, then the reaction of the potatoes weight would have happened slower. If someone used animal cells instead of plant cells in this experiment, nothing would change because the only difference between plant cells and animal cells is the cytoplasm which has nothing to do with the experiment. A solution that is five percent glucose would be isotonic compared to red blood cells.
Since the vinegar had more water molecules than the egg, it was transferring the molecules to the egg to create equilibrium; therefore, the egg became larger. This proves that the egg has a higher solute concentration then the vinegar. However, when the egg was placed in the corn syrup, its masses greatly decreased. The corn syrup has no water molecules, so to create equilibrium, the egg transferred its water molecules to the corn syrup,
is the results of the effect of enzyme concentration on the potato enzyme. The 100% enzyme concentration had the highest average rate of O2 production being 7.79ml/min. This is because when there is a 100% concentration there is more molecules of the catalase for the hydrogen peroxide to react with. As the concentration is being diluted, the concentration of the catalase is decreasing so the molecules are less likely to collide and react. When the enzyme is at a 0% concentration there should not be any 02 produced and this is where some errors may have occurred.
Here are even more nutrition facts. Some foods contribute to burning fat. Green tea contributes to fat burning by increasing the body's metabolism and increasing energy level. Foods high in protein are more difficult to digest so they require more calories in the digestive process. Good nutrition practices may not be sufficient for some people they may require unique supplements such as CoEnzimeQ10 or
Plasmolysis takes place as the cell loses water. Whereas if the piece of potato were put into a solution that has a low concentration of sucrose then the potato piece would increase in mass because the water is moving into the cell, which means the water is moving from a higher concentration (solution) to a lower concentration (cell). The cell is hypertonic and the solution is hypotonic. If the potato piece were put into a solution that was of an accurate concentration (which means that it was neither concentrated nor dilute) then the potato slice would neither gain nor lose mass because the concentration of water and the solute (sucrose) is equal in both the cell and solution. Both, the cell and the solution are
This indicates that all of the solutions have been hypertonic in relationship to the potato tubes. The concentration of the solute (salt or sugar) has been higher in them than the concentration of the solute in the solutions that we have tested them in. Nonetheless, some solutions have been a closer match to the osmolarity of the potato tubes than others, such as 0.6 (M per mL) which has caused the tissue to lose -3.6% of its weigh only, compared to 1.0 (M per mL), which has caused the potato to lose -36.6% of its weight. Therefore, the net movement of water in the solutions that displayed a bigger loss in the weight of potatoes has been higher than solutions where the potatoes have only lost a small amount of their weight. This indicates the bigger the weight loss in the mass of the potato, the bigger the difference between the two concentrations of the potato and the solution that it is soaked
The crystallization results from the formation of monohydrate glucose crystals, which vary in number, shape, dimension and quality with the honey composition and storage conditions. The lower the water and the higher the glucose content of honey, the faster the crystallization. Temperature is important, since above 250C° and below 50C virtually no crystallization occurs. Around 14°C is the optimum temperature for rapid crystallization, but also the presence of solid particles (e.g. pollen grains) and slow stirring result in quicker crystallization.
Thus, as Malcolm Gladwell states, "rice farmers improved their yields by becoming smarter, by being better managers of their own time, and by making better choices" (Gladwell, 233). Because working in a rice field is ten to twenty times more labor intensive than working on a corn field, Rice farmers had to work harder than almost any type of farmer. However, their hard work led to a high yield of rice. Therefore, rice farmers were able to learn an important lesson: hard work pays off in the form of success. This lesson was passed on throughout Asian culture and has become an important virtue even in today 's society.
So they would take genes from something like a watermelon and put it into something like corn. Then once the corn grows it is much bigger than 3-4 inches so now the corn/corn stalk is 10-12 inches long and helps meet the demands of a singular person, so instead of one person buying around 5 heads of corn they would buy 1 or 2 and makes it much cheaper now that they are bigger and in greater numbers so it is much more ideal for the common farmer and even more important the economy as a whole. Bio engineer’s also have to create specifics according to the people’s demands such as how we needed more lettuce so they used the genes from both a watermelon and a tomato to make it bigger and for the stem to be much more durable yet much easier to pick. However in order for these things to work bio-engineer’s also have a difficult time deciding what genes go together and which ones do not. They do not want a product to be too squishy or too small or too big so they have to conduct many, many tests in order to figure out if the “new” plant is exactly what meets the demands of today’s people and
Flanagan explains in her article, “ American kids are fatter and sicker than ever.” Building gardens at each school will not only improve student 's attendance but will help them eat better. Not everybody agrees with putting gardens in each school the real question is, “what are you doing to prepare these kids for college?”(423) Building gardens in school can be a good thing or a negative thing. Flanagan is trying to make it seem that building gardens in school would make kids graduate high
The change in stimuli makes the chicken believe it is spring, and in consequence, lays eggs. Chickens and turkeys lay two or even three times the eggs than they would if in nature. After the first year of inhumane egg produce, those chickens are killed because the amount of eggs they produce each year gets fewer. These practices are why poultry meat is substantially cheaper than other meat, but at the cost of animal
