Pinto beans or in other words common beans are the most abundant beans in both Americans, making it major source of daily nutrients for large number of civilians. This experiment was done to examine if the number of seeds used in a specific area would affect the growth process using two pots (Control, Experiment). Control pot had two Pinto beans, while the Experiment pot had four seeds. Both pots were placed in the same room with same amount of water supply and light.…
My hypothesis that the germinated peas would consume more oxygen than the non-germinating peas was accepted. Looking at the results the germinated pea results of how much oxygen was consumed was much higher than the ungerminated peas. The hypothesis that the P. savitum would rise in oxygen consumptions as its temperature rose was accepted as well. Looking at the data and the line graph, it is clear that as each temperature got higher the amount of oxygen consumed went up as well. Most enzyme activity after 45ºC generally become denatured and can’t function properly.…
5 Table of contents….. 6 Experimental procedure….. 7 Work cited…..8 Experimental procedure Experiment: First off I wanted to see how I could compare bread without water to bread with water so I got two pieces of bread and took a bottle of regular water and wet one of them down then I put them in a ziploc bag for a little over a week.…
All of this matters and is important to know about because it is key to understand the background of the experiment beforehand. This investigation relates to past research based on the…
ABSTRACT: The purpose of this lab is to describe possible genotypes of corn and plants in procedure 17.2, and find their color and height ratio; in procedure 17.3 codominance will be observed in human blood, and the blood types of unknown samples will be determined. In procedure 17.4, Rh positive and Rh negative will be tested for in blood samples. A unit of heredity on a chromosome is called a gene.…
The author, Michael Pollan, believes that feeding corn to cattle is bad for the cattle. To begin, Pollan states that, “Basically, almost all of the cattle in the feedlot are sick and it’s their corn-based diet that makes them ill” (58). He explains that since all feedlots feed corn to their cattle, most of the cattle are sick which means the cattle aren’t healthy. He also goes on to explain that, “Cattle rarely live on feedlots diets for more than 150 days…” (59). This means that the cattle on a feedlot don’t live for a long time which means there is a large amount of deaths in a feedlot.…
Native Americans stored corn until it dried out. The dried corn was made into hominy by soaking corn into water until the kernels split open. These would be fried over a fire. Native Americans would also ground corn into cornmeal. Corn was put into the hollowed out mortar and then by pounding the corn with the pestle, this would grind it up into a powdery form.…
In this experiment, the problem that was being investigated was the effect of Miracle Gro on the germination of lentil seeds over a period of three days. This problem was investigated in the interest of Ms. Semaan and her past experiences with lentils. She and her family had previously grown lentil seeds seasonally and compared them to her relatives’ seeds in terms of growth and height. More often than not, the relatives’ lentils grew better than those of Ms. Semaan and her family, and she had wanted to know the reason why these results had occurred.…
Denby: The first five paragraphs develop the archetypes of the popular girl and head jock that are constantly used in the typical teen movie genre and accentuates the fact that these archetypes inaccurately reflect reality for the majority of teens in high school. When Denby asks “Do genre films reflect reality?” he assumes that we know what genres, films, and reality are. Both of the terms “genre” and “film” can be easily defined, but “reality” can change from person to person.…
Abstract The purpose of this experiment was for the researcher to study one of the process of digestion which is absorption, and seeing if starch and glucose could diffuse through the dialysis tubing, and could the two be absorbed by the small intestines, and if so or not, why? To begin, in this experiment, the researchers gathered different solutions, such as, starch and glucose, filling half of each mixtures in a single dialysis tube. The researchers carefully then rinsed and pat dry the dialysis tube, to insure that the nutrients were removed. By placing the tube in a 250-mL beaker, submerged in 50-mL of distilled water.…
In this experiment, we set out to determine the osmolarity of a potato. In order to do this, we placed potato pieces in seven different solutions of varying sucrose molarity. First, we weighed each potato piece to obtain the initial weight, shown in Figure 1. Then, we split the pieces vertically before placing them in the cubs containing the sucrose solutions. In each cup was a solution of sucrose with a molarity ranging from 0.0M to 0.6M. After placing the potatoes in the cups, we allowed them to incubate for an hour and half, swirling each cup every fifteen minutes.…
The independent variable in this experiment was time which was 10 minute intervals. The dependent variable was the weight of the raisin before and after each interval. And the control was the water temperature each raisin was placed in, which was Hot, room temperature, and cold. Hypothesis:…
Title Sugar water versus salt water: What effect did they have on seed germination? Purpose The purpose of this experiment was to figure out what types of water would have an effect and what that effect would be on seed germination. Background information Plants need nutrients to survive.…
Cecilia Wong Nature of the task and the research question: Two centimetre piece of potato is bathes into different salt solutions (0%, 5%, 10%, 15%, 25%, 35%) over a period of time, to determine the effect of different salt solutions on osmosis. To investigate the effect of increasing the concentration of sodium chloride (0%, 5%, 10%, 15%, 25%, 35%) on the process of osmosis, by calculating the mass change of the potato core (g, ±0.01g) at room temperate of lab (25.0˚C) Table 1: Raw data Table of Random uncertainties Equipment Limit of reading Random uncertainties Electronic balance 0.01g ± 0.01g Ruler 0.5cm ±0.5cm Table 2: Quantitative raw data The mass of the potato core (g, ±0.01g) at different sodium chloride concentrations (0%, 5%,…
In experiment 2.1, absorbance readings for both heated and unheated corn and tapioca starch were taken. For both starch’s the heated results came to be much higher then the un-heated as seen in Table 2.1. Iodine reacts with the amylose compound in starch where it gets trapped in the amylose coils and blue-ish colour is formed after the addition of Lugols reagent (Fennema and others 2008). The absorbance readings came out higher for heated corn starch because iodine had more amylose to react with. As corn-starch is heated gelatinization occurs where amylose is released since the starch granule is disrupted.…
