These chambers were to see the yeast cells in a microscopic view and if or if not our hypothesis were true. The materials that were used a compound light microscope, a Pasteur pipette, and a hemacytometer to view the cell count of collected yeast. The methods that were go about was simple, to view the two cultures and compare them both. As a result of the t-s value was .035, as the value was lower than the critical value it’s said it’s being rejected. Thus as our experiment has been rejected our hypothesis comes in a stand still whether antibiotic dose really effect yeast cell cultures.
The serving size indicates the amount that is good for 1 person as well as how many serving are in the container. It is best to stay below 5% and NOT go over 20%. For instance, the percentage of the total fat in the can of Healthy Choice is only at 2%, which is great because fats are not a source of nutrition, therefore, it is best to limit them. The 6 Key Food Facts To further understand the nutrition label, we must be able to identify the six key food facts that are presented. 1.
Fact or Guess: Hypotheses and The Scientific Method John Storrs SC235 Unit 1 January 10, 2012 Kaplan University Professor Travis Kibota Hypotheses and The Scientific Method Assignment Question 1: Read the scenario below and then analyze what is wrong with the hypothesis given. Renee has noticed that a few of her friends have better eyesight than she does. She watches what they eat and then decides to come up with a hypothesis. Her hypothesis is as follows: My friends who eat tasty food for lunch have the best eyesight. Initially, Renee has completed a brief observation period, provided her hypothesis; however, concluded prematurely without conducting any type of study.
The number of swimming brine shrimp for Trial 4 was slightly less than that of Trial 1. This could be due to oxygen levels in the lab, or it could be due to human error in counting the numbers of eggs from the procedure, or counting the numbers of swimming brine shrimp and dead brine shrimp in analysis. Additionally, actual amounts of ethanol concentrations could have slightly varied due to human error in measuring the ethanol consistently among groups causing slightly variable viability rates. Water may also have splashed out of the dishes, contributing to a flaw in measurement. In the future, the entire study should be performed by individual groups in order to aid elimination of error.
6. Footnote with daily values (DVS) the percent daily helps to recognize whether or not food is rich in nutrient. This is where the rule 5/20 comes in like if the food item you have only contains 5% DV than that food item is not beneficial for a human body be careful though certain nutrients. A food should only have ½ cup serving size but the serving size may be 21/2 servings when looking at calories it should show you the amount of energy that you will get from a single serving. The nutrients are what you will want to get the least like cholesterol, Trans fat, and fat.
Less germinated in the presence of 1% ammonium nitrate compared to the spores not in the presence of ammonium nitrate. In other studies done, when ammonium is used to provide the nitrogen source for photosynthetic spores, they will not grow or germinate properly, and may show abnormalities and inhibited growth (Melan & Whittier, 1990). That is exactly what our experimental data showed us. After preforming the tests and compiling all the replicate data, we found that in the control group there was an average of 50.5 germinated spores per plate. In the plates containing 1% ammonium nitrate there was an average germination rate of 28.5 spores per plate.
Carmen believed that the more salt, the lower the temperature is. It is incorrect. The lower amount of salt, the less time it took to freeze. 3. I would suggest to Carmen that she maybe would give herself more time to let the water freeze because when she added 5 grams of salt, it did not freeze in enough time of the experiment.
Based on the pictures that we saw, there was a lot of wild life that didn’t depend too much on water. We developed the hypothesis that construction nearby is not having an adverse effect on the Turtle Bay Estuary. We predicted the estuary will fall around 4 ppt, making it safe to live in. Method To properly assess the conductivity based on the salinity, we created six different solutions with a certain balance of the Turtle Bay Estuary stock sample and distilled water. Using a conductivy probe for each sample, we will determine the salt content of the water.
Then they stay there until they become thirsty again. A couple of errors may have been that we had not used that many pill bugs. In my investigation we only used about 4 pill bugs witch may not be enough to know for sure. If my conclusion is right however, then the only explanation I have is that the pill bugs used kinesis. This is a random turning point or movement of an animal in relation to stimulus.
This restaurant was only three hundred and eighty four square feet of space; however by having such a limited amount of space Cathy was able to keep cost down. Cathy opened this restaurant for seventeen thousand dollars an amount that was far less than he anticipated. Opening restaurants in malls Cathy concluded was a way to get more selling capacity per dollar (Fame, 2005). The menu for the restaurant was simple, it consisted of five items; boneless chicken breast sandwich, potato fries, coleslaw, lemon pie, and lemonade. Over the course of years new items would be added to the menu; however the original Chick-fil-A sandwich would always be the leading sandwich.
