The Effects of ECB on Corn Crop Yield Abstract In this experiment we explore the infestation of ECB (European Corn Borer) on different types of corn and how it effects the corn crop yield. The corn is grown in a controlled environment with the only changing variables being the type of corn and the concentrations of the infestation of the ECB. Varying levels of infestation are tested on a corn crop throughout a 140 day growing season‚ at the end of the season the crops are then measured for

In recent history‚ many people have become wary of the infamous genetically modified organisms (GMOs)‚ which are commonly found in many foods and products‚ from corn to cotton. However‚ there are a series of documented dangers associated with GMOs and they have caused a divide between those who support GMOs and hope to reassure the consumer that GMO’s are safe‚ versus those who oppose GMOs and promote the removal of them from their favorite products. Despite strong arguments from both sides‚ there

business model to agriculture. In this business model‚ companies invest heavily in research and development‚ and recoup the expenses though the use of biological patents. Monsanto’s genetically modified corn is usually called Bt corn. Bt comes form Bacillus thuringiensis which is a soil-dwelling bacterium‚ commonly used as a biological pesticide. You may wonder why does the name of GM corn come from pesticide. The production of genetically modified corn is carried out as follows: the corn ’s DNA is

to the people. Instead of helping the people these notifications seem to be providing health problems (Agadoni). The products that the scientists put within these crops prove to only increase allergies for the people. Scientists use a bacteria‚ "Bacillus thuringensis"‚ to keep the insects away from the crops while they are being grown. Smith has proved that the only thing BT keeps away is the chance for the the immune system to fight off allergies. The test that was ran was performed on mice‚ and

Systematic Identification of Bacillus subtilis and Serratia marcescens Through a Battery of Tests and Plates Introduction: The purpose of this experiment was to use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to

Genetic engineering of plants (crops) Pros|Cons| Less tillage needed‚ especially with crops containing herbicide tolerance transgenes‚ therefore conserves fertility through minimizing soil damage through compression. |GE agriculture claims low tillage weed control: this can be achieved by ending the practice of monoculture and instead introducing proper crop rotations designed specifically to combat the weeds of the particular locality. Monoculture creates a weed paradise. | All countries face

Among the reports‚ several have shown the relationship between GMO cytotoxicity as well as the teratogenic potential in mammals. Specifically the toxins glyphosate‚ and Bacillus thuringiensis (Bt) present a combined area of concern as these herbicide resins and insecticidal toxins are present in Roundup-tolerant GM plants such as corn‚ soybeans‚ canola‚ cotton‚ sugar beets‚ and alfalfa.

Essay 3 - Argumentative Essay Topic: Genetically modified food should be strictly controlled due to its various detrimental effects on the environment as well as human health. Every time we go to supermarkets or any grocery stores‚ we would not know whether the vegetables‚ fruits or even meats being sold are genetically modified. To make this situation worse‚ most consumers do not pay much attention to what they are eating‚ when they are actually devouring genetically engineered food. Despite

(Wu‚ 2006) The prefix ‘Bt’ from Bt-Corn originates from Bacillus thuringiensis (Bt)‚ a species of soil bacterium that produces the insecticidal crystal protein or delta endotoxins‚ toxins that kill crop pests.
