It is a soil microbe that was used to put foreign genes into plants and made it possible to improve crops. At this time, some animals were also starting to have their genes modified in a similar way. In the 1990s, people who knew about GM foods wanted it to be regulated. They argued that the food is changed and should be treated as a food additive so they should be regulated by the FDA (Food and Drug Administration). At this time, there are still a lot of things unknown about GMOs and how it affects humans and the environment and going organic is the best option right now.
Genetically modified foods are plants that have had their genetic characteristics altered. 2. What foods can be created by genetic modification? Sweet corn, rice, tomatoes, rape plants, and animals 3. Name 4 examples of genetically modified crops.
By using the genes from two bacteria producing organisms such as Alcaligenes Eutrophus, they could insert them into cress plants with the aim of these plants producing the PHB. This process worked and the plants and some of their offspring produced around 14% of the dry weight as PHB. Although this is not as high yielding as when it is produced in the petri dishes, it is a much more economically viable method of production and hence would give a much more substantial impact to society. Chemically PHB is from a group of biopolymers known as the polyhyroxyalkanoates. Figure 1 below shows other examples of biopolymers in
Aerobic metabolism fuels most of the energy needed for long duration activity. It uses oxygen to convert nutrients (carbohydrates, fats, and protein) to ATP. This happens in the mitochondria of the muscle cells it differs from the other two energy systems, as it requires oxygen to resythesize ATP. The aerobic energy system produces the largest amount of energy but it is mainly at its lowest intensity. When we start an exercise our bodies cannot deliver oxygen to the muscles fast enough therefore it heavily relying on the anaerobic processes for the initiating actions.
1-2-09 Glowing Bacteria Genes are pieces of DNA which hold the instructions for making proteins. The protein will then give an organism a particular trait. Genetic transformation means changes caused by genes, and requires the insertion of a gene into an organism, in order to change the trait. this technique is used by in many areas of biotechnology. Agriculturally, plants can be genetically transformed to be resistant to pesticides, spoilage, and frost.
Hybridization- crossing different traits to bring the best of organisms into one. For example crossing disease resistance of one plant with the food-producing capacity of another to produce a superior plant. 3)Cloning is the process of taking a single cell from an adult organism to recreate another genetically identical organism. 4)DNA fingerprinting is developed by molecular biology; it analyzes unique sections made up of a variety of DNA band. DNA fingerprinting is a powerful and crucial tool that can determine a person’s identity.
They can also reduce carbon dioxide emissions. 3 New Vocabulary Words: 1. Microplastics - n. small plastic particles in the environment 2. Polycyclic aromatic hydrocarbons - n. organic atmospheric pollutants that are present in fossil fuels also known as
As for the growing end of the spectrum, Pollan then goes on to say that “It (corn) had to adapt itself not just to humans but to their machines” (30). Farmers eventually found inventive ways to mass produce this crop. Planting the crops in such a close proximity created not just more space, but also caused the plants to grow upward. This meant that it was easier for machines to come in and extract the corn, so this ushered in the use of fossil fuel. These machines were created not just to cultivate the land, but to also apply large quantities of chemicals to the crops to prevent insect infestations.
If automobile composites use hemp because of its durability then the bodies themselves could be made from hemp. Even computer frames could be made from hemp. This kind of change would save landfills and plastic disposal sites a lot of much needed space. This is a unique plant that is very strong and grows easily; it could help humanity sustain itself. We could use all our resources for other things and hemp could replace the shortages of goods.
Since it is a plant it will help reduce the “green house” gases and pollution in the air, not to mention making a cleaner burning fuel source to replace gasoline and reduce the amount of pollution even more. The plant also does not take much soil space and can be grown in between other crops such as corn. Hemp as long roots so that it improves soil structure and replenishes soil with nutrients and nitrogen and helps control erosion of topsoil. Also, once harvested, any residue can act as eco-friendly manure. It is also a weed suppresser to prevent other weeds from growing because it grows so fast and densely, it blocks out sunlight to other weeds that are trying to grow.
