Maize Experiment: Methods
The maize, or corn, experiment was conducted to observe the results of a monohybrid or a dihybrid cross between two different types of corn. This particular experiment required samples of various types of dried corn, preferably corn the sustain features between color and texture. These different colors and textures include purple, yellow, sugary (smooth), or starchy (wrinkled), respectively. The experiment is started by taking an individual stalk of corn from each type available, in this case three different types. Each stalk of corn was then observed carefully and their kernels were being observed, and counted
with the data being recorded and grouped together. After each stalk of corn is counted and the data is recorded, a chi squared test was conducted to answer some questions about the phenotypes and genotypes of the different stalks of corn and the progeny that would result if the originals were crossed (monohybrid or dihybrid). After observing and doing some calculations while utilizing chi squared tests and Punnett squares, the results were recorded and the questions are now able to be answered.
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
Corn is a high commodity in the U.S; our ham, eggs and pancakes for breakfast, California BLT at lunch, or double cheese hamburger for dinner were all produced with U.S. Cor...
The results of this experiment are shown in the compiled student data in Table 1 below.
Conclusion In my conclusion, the potatoes with the lowest concentration gained the most mass, and would become hard relating back to the Turgor theory I stated earlier. In contrast to this, the potatoes in the most concentrated solution lost the most weight thus becoming plasmolysed and limp also relating back to the background I have mentioned earlier. Evaluation In general the experiment was succesful the results were consistent and also were in accordance with the theories made at the start.. The experiment could have been improved by: · More subjects used instead of potatoes · More potatoes · Wider time ranger · Different molarities Using this variety of methods could have improved the experiemnt, however I was generally satisfied with the results of this osmosis experiement.
Corn, or maize, plays a vital role in many areas of the world today, and each location views and handles corn in a different way. How they manage corn can show small details about the area and culture as a whole. Not only is corn a staple today, it also had a huge presence in the ancient Native American’s lives; corn is sometimes revered as a deity and other times as a gift to the people from the Creator or a hero of the culture.
Maize was first introduced to the Europeans by the Taino Indians. The American Indians used this crop for a variety of reasons to even include worshipping “maize gods”. Maize would be able to provide for humanity more than any other crop. The Old World had the labor power and land to produce such crop. Continuously growing in the vast majorities of fields, the crop is protected by its husk from the weather, birds and rodents. Being able to grow in most any type of weather condition, mai...
* Amount of sugar solution in each test tube. * The potatoes have to have the same mass.
Materials used in the experiment included 5-7 g of the potato tissue, 50ml of 2.0M phosphate buffer coffee filter and guaiacol dye.
WHEN Zhang Yimou made his directorial debut, Zhang Yimou made his directorial debut, Red Sorghum, in 1987, he was better known as a cinematographer whose talent had been crucial to the success of critically acclaimed films like Zhang Junzhao's One and Eight (1984, released 1987) and Chen Kaige's Yellow Earth (1984). Not only did Red Sorghum become a seminal film of the Fifth Generation, it also won the Golden Bear at Berlin in 1988, becoming the first mainland Chinese film ever to be awarded the highest honour at a major international film competition.
Each Biology 108 section planted these pots and the data from every section was to be combined for an overall data sheet. Our group in section 6 had the role of planting 5 of the experimental pots with the assigned number of wheat seeds or mustard seeds or both.
After the disillusionment following the 1832 Reform Act, British radicals were determined to make their voice heard in the next decade. As a matter of fact, the limited extension of franchise greatly disappointed the people in favour of reforms, and the protectionist attitude of the government was considered as a threat to both the British economy and the well-being of the working-class. In 1815, the Corn Laws had been implemented to regulate the prices of corn and protect the domestic production from the cheaper products of the continent. However, these measures were widely contested in the mid-nineteenth century because they stood for the old conservative England and were thought to be harmful to the development of the country. In a time of popular mobilisation and radical agitation, movements claiming the repeal of the
The purpose of this experiment is to compare the ability of students in tasting PTC. The hypothesis formulated for genotypes states that there is a significant difference between tasters and non- taster, with the null hypothesis stating that there is no significant difference between taster and non- taster. During the phenotypic observation two different hypothesis were formulated as well, there is significant difference between the three observed phenotype and the null hypothesis states that there is no significant difference between the three phenotype. Through observation and calculation it is concluded that there is a significant difference between the Genotypes. On the other, there is no significant difference between the phenotype.
According to writer and environmentalist Vandana Shiva, "the crucial characteristic of monocultures is that they do not merely displace alternatives, they destroy their own basis"(1993, p.50). If the self-destruction of a monoculture is really so simple, it seems that continuous cropping agriculture should long have been abandoned for a more suitable method. Unfortunately, the problem is far more complex. This paper will focus on the effects of corn monoculture on soils in general, the development of the monoculture in the United States and the effects this had on soil in this country. Through the exploration of other models, suggestions will then be made on how to modify the continuous cropping system in the United States into a more sustainable one.
According to Steven Aitchison “Never give up on your dreams. The waiting can seem painful, but the regret of not going for it will be even more painful.” In other words readers learn that when you accomplish something it feels good, but when you don’t, you regret not working. In Wilson Rawls’ Where the Red Fern Grows, he develops the theme of never give up on your dreams and goals, fore you will regret.
== = This experiment is based on the concept of Osmosis. Osmosis is the diffusion of water molecules from a region of high water concentration to a low water concentration through a semi permeable membrane (in this case, the cell potato cell membrane). The cell walls of the potato cells are semi permeable meaning that water molecules (which are small) can fit through but other bigger molecules such as glucose cannot pass through. The water molecules can flow both ways through the membrane, letting molecules both in and out.
