Celery started with a pH of 6.05 and dropped down to a pH of 5.03 after 30 drops that is not nearly as drastic as alka seltzer. But, it shows how celery does not have a buffer because of the drop in pH and is not able to create more hydroxide ions when acid is added. Liver started with a pH of 6.50 and after 30 drops the pH dropped down to 6.03 which means the drop in pH is only .47 and looks similar to the data of the positive control of alka seltzer. The data in this lab follows the hypothesis of testing the HCI of liver and celery, then liver will contain a buffer and celery will not. This conclusion can be drawn because of celery’s large drop in pH and the data’s resemblance to the water data meaning celery cannot hydrolyze ions and keep a constant pH. Liver’s pH only changed by .47 which is not a dramatic change and can fall within scientific error and strongly relates to the alka seltzer data.
This could of happened because a bit more than 10 g of popcorn was added, someone with sweaty hands might have added extra bodily salts to the popcorn, or not all the water was squeezed out of the popcorn. Conclusion: In conclusion we did experiments to find out the salt and fat content in 10g of popcorn/chips. So that we could then compare it to what the packet says to see if that is correct or not. In the end our results did not correspond with the answers on the packet.
The egg had been acting as the cell in this experiment. Placing the egg in vinegar made it easier to see the effects of osmosis because there was no impermeable shell to prevent liquids or molecules from passing through. As previously stated, water molecules will diffuse from higher concentrated areas of water to lower concentrated areas of water. In the tap water example, there had been a higher concentration of water molecules in the water, not the egg. This means that the water molecules will pass through the cell membrane to enter the egg and reach a state of equilibrium.
(1997) find no evidence of deterministic patterns in Australia and Hong Kong equity returns. 3. Research Methodologies 3.1. Rescaled range (R/S) analysis Whether the stock price movement follows a random walk or not can be detected by the rescaled range analysis or R/S analysis.
The Marshmallow Theory Have you ever wondered, “where does willpower come in place for success”? Can a marshmallow and children be the best explanation? According to Walter Mischel, it is completely possible to use 4 year olds with marshmallows to determine what willpower has to do with success. He simply leaves the child alone with one marshmallow for several minutes. If the child waits till he comes back before eating the marshmallow, he gets a second one.
“The ideal industrial food consumer would be strapped to a table with a tube running from the food factory directly to his or her stomach,” is one example of Berry’s use of imagery. Berry provides the audience with a sarcastic, vivid image of a lazy person being tube fed straight from a food factory to emphasize how ridiculous everyone is becoming. Likewise, he does this to make the reader come to the conclusion that the way that many people eat has gotten out of hand. On a lighter note, Berry provides his audience with an appealing image. He says, “If I am going to eat meat, I want it to be from an animal that has lived a pleasant, uncrowded life outdoors, on bountiful pasture, with good water nearby and trees for shade.”
Through aqueducts, water was transported to the baths and heated through a hypocaust system that utilized the natural resources in Bath. The baths themselves required great cooperation, so it is no surprise that this value continued to contribute to Roman culture inside the public baths. I personally find that our culture can be oppressive in its inherent competitive nature. We should be able to cooperate and communicate in our personal and professional lives without impacting our opportunities for success.
Conical Flask I'm using a conical flask as it is a good way to react chemicals in because it allows a bung with a delivery tube to be connected to the top to collect the gas, whereas beakers you cannot. Gas Syringe I chose the gas syringe over the measuring cylinder in water because it allows me to see the product produced going up in smaller sizes because of the scale on the syringe. So the timer can be stopped exactly when it reaches the value needed. Bung and Delivery tube To ensure that no gas leaks out of the conical flask, so that the volume of gas inside is delivered to the syringe.
Thus for thirsty subjects whose active need is to quench thirst, a relevant advertisement could be more persuasive if it co-occurs with subliminal messages of thirst related words or picture. Similarly, Karremans, Stroebe, and Claus (2006) carried out an experiment which demonstrates the same idea. They exposed the thirsty subjects to the subliminal priming of the brand ‘Lipton Ice’ and demonstrated that it affected subject’s choice as well as purpose to
Similarly, on page 2 of “Insect Farmers” it says “It would also reduce the environmental footprint.” This is similar because both articles are saying that eating bugs is good for the environment with different reasons. The poisons that the average citizen uses to kill bugs washes away in the rain and could not only kill bugs, but other wildlife too. In both cases eating bugs is good for the environment in many different ways. A second similarity is that eating bugs is healthy for you.
Dog Fly Another of the dangerous pests near beaches is the dog fly. This fly is known to bite dogs and therefore gets its particular name but it does not hesitate to bit humans as well. They are a hazard slightly north but if the winds are right, the dog fly can be a pest in southwest Florida which is a persisting
Can heparin injections every 12 hours instead of every eight continue to provide protection against DVTs due to the life of the pharmacokinetics? 3. Could this research improve our patient scores for satisfaction if patients only had one injection a day, not three? 4. Would our satisfaction scores go up if we did not wake them in the middle of the night to do an eight-hour heparin subcutaneous injection?
Synthetic Sea delves deeper into the environmental burden that plastic is placing on the oceans. It shows the effects on not only the oceans, but on animal life as well. (2) Tamara explains why she feels that tap water is superior to bottled. Some of her reasoning for this is that bottled water regulation enforcement is the job of only one person who also possesses additional responsibilities. The evidence also found that bottled water is no cleaner than tap water when tested.
In fact, through a recent study at Princeton University, after observing changes in rats that consumed high fructose corn syrup, scientists were able to conclude that the cheap sugar substitute has addicting effects on the brain “similar to some drugs of abuse” (Parker, 2010). Behaviors that individuals who take in excess amounts of HFCS encounter such as binge eating, withdrawal, and craving, for instance, all relate to the same neurochemical change, where enkephalin mRNA, dopamine, and acetylcholine release in the nucleus accumbens, in the brain that occur in humans addicted to drugs (Avena, 2007). Thus, in the same way that a drug fiend depends on drugs humans begin to depend on High Fructose Corn Syrup, both needing their daily fix which is especially apparent in the growing number of overweight people since HFCS became present in nearly every processed food (Avena,
a lot of what Brian thinks he knows a lot about survival, but his knowledge often comes from tv shows and movies. however Brian begins to learn about his environment and matures his survival instincts. he first recognizes his disadvantage in nature, when he begins collecting collecting food and wood. he understands he has to get enough food and wood, not just for the present but also for the future incase he were to ever get hurt or injured. one of the best realizations that Brian figured out while in the wild is that, everything in the wild is constantly trying to eat.
