We then obsevered the two slides for number of cells as well as for food vacuoles inside a cell using a microscope at times of 0,5,10,20, and 30 minutes. Results The following graphs show the results of this experiment. The tetrahymena sample that was introduced to concentrated tobacco had a lower cell/vacuole ratio than the tetrahymena sample that was not exposed to
Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.
Obtain a small sample of the red epidermal cells from the stalk of the rhubarb by carefully peeling away the layer with forceps. Prepare a wet mount slide of the rhubarb tissue in distilled water only. View your slide under low power on your microscope, and then switch to high power. Draw a diagram of the field of view, and label.
Now that was what we took
Title: How Ph Levels Affected the Fermentation of Beer Hypothesis: The beer will be left with more sugar deposit as the Ph levels increase because alpha/beta -amylase will no longer function. Predictions: Alcohol Percentage Analysis for the Control and the Experimental During this experiment, the pH level was increased, therefore Alpha-Amylase was favored. Due to the nature of Alpha-Amylase cutting randomly through a large carbohydrate molecule, it leaves bigger sugars in the flask, which cannot be digested by yeast. Due to this, less reactions should occur in the experimental, therefore leading to a lower percentage of alcohol production, compared to the control.
While performing the slime lab, we were trying to find the effect of borax on glue and water. We mixed glue and water together and added small amounts of borax water to it. We wanted to find the difference in stretchiness with different amounts of borax. After adding the borax, we measured how far the slime could stretch. We hypothesized that the slime would stretch farther when more borax was added.
If I had a chance to do any of these experiments again, I would choose to go more into depth for the dampness experiment. I would hold the experiment for a longer time period so that I can prove that if the mealworms were allowed to remain on the damp surface for excessive amount of time, the amount of dampness would become harmful to the mealworms as their bodies might start to rot and get infected. If I were to do the food experiment again, I would worms in the soil before putting the food into the container. I would do this because when I gave the worms a thin slice of apple (not part of experiment), they all came up to the surface of the soil to eat the apple. I could tell that the worms ate the apple because on the next day, only the skin
In every part of the surrounding, in which humans dwell in, no matter in water, land, air, or elsewhere, there reign tiny yet complex lives. The in depths study of these living organisms bring human a face to face consequence with an astounding miracle of the creation of God. The astounding part of the living organisms have led us some understanding of the awe-inspiring structure of every life from as small as 0.0000001 to over 0.1. These photomicrographs unveiled the miracle and astounding lives as illustrated below. This microscope image was captured by Spike Walker.
Next Hans Spemann 's first test was to make sense of how to part the two cells of an incipient organism considerably stickier than ocean urchin cells. Spemann formed a noose from a strand
Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
Focusing on the commodity of white bread, one might believe that consuming bread is an act of eating that has become a basic necessity in almost every home around the world. Many individuals would not question bread because it is always found on the shelves of grocery stores making its way into their homes in a cheap, fast and convenient way. For Aaron Bobrow-Strain, bread has become much more than a simplistic commodity, in his book he is able to use bread as a metaphor to illustrate issues of power and also examine the way that we think about our social lives (p. 167&169). His book reveals the history of white bread in order to describe the social dynamics associated with this commodity while also focusing on issues of racialization, gender
Conclusion In conclusion my hypothesis was right and the wet bread grew the most (and only) mould. I can logically assume that the more moisture the bread has, the more mould it will grow. This was a fair test because each of the bread pieces had equal time to grow. The End In this experiment the conductor finds out that mould needs moisture thus needs to be included to conduct the experiment.
Moisture- 4.0% maximum Solubility- 98.5% Color- white • SMP combines with the gluten in wheat to produce soft and moist dough for baking. • It increases the nutritive value. • It helps to give shine to the product.
