What is the benefit of the modification? Because the GM tomatoes can remain fresh longer they have time to ripen in the sun before picking, resulting in a better tasting tomato! 4. Three advantages of genetically modified foods Longer lasting foods can be more easily transported, Having extra vitamins in food help poor people from becoming malnourished or going blind, and the insecticides inside some genetically modified plants keep farmers from having to spray the whole place down with toxic wastes, and they also 5. A counter argument to one of the disadvantages of genetically modified food Some antibiotics can be transferred to humans and make it harder for us to fight infections, genetically modifying foods could potentially put farmers out of work, and some important insects could be at risk because of the insecticides in foods.
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
Instead, try some changes to your diet to include some of these stress-reducing foods. Stress-Reducing Foods Foods rich in vitamin B. These include oatmeal, lentils, chickpeas, quinoa, brown rice and other whole grains. Foods high in vitamin B have a calming effect on the body, helping to melt away feelings of stress and anxiety and enhance your mood. Foods rich in vitamin C. Citrus fruits, red peppers, spinach
1) Genetic engineering or genetic modification is the process of altering an organism’s genetic material for a beneficial purpose. Genetic modification is used to improve the products we obtain from plants and animals making them more nutritious, less-harmful manufacturing processes, and production in large quantities making them less expensive. 2) Gene Therapy- when an absent or faulty gene is replaced by a normal gene in order to treat a disorder or medical disease Plasmid- small circular DNA molecules in the cytoplasm of bacteria, these molecules cut DNA into a recognizable sequences DNA Polymerase Chain (PCR)- technique used to make copies of a certain gene. Biologists particularly use this with tiny genes that are rarely available. Hybridization- crossing different traits to bring the best of organisms into one.
Compare the benefits of growing GM seeds for crops with the potential negative consequences of using them? The benefits of growing GM seeds for crops is that the seeds are more resistant to stress and the crops can overcome pest outbreaks and reduce the danger or crop failures. The crops can endure severe weather such as frost, extreme heat or drought. Now the negative side effects of the GM products is for example the wind blowing to different fields were other farmers may prefer not to use enhanced seeds. They are modified with herbicides and pesticides so the uncertainty of health consequences of humans consuming the food grown by these seeds exists.
However, using the juicing method would require a large amount of vegetables to obtain the desired 12 ounces. It would also require more effort to chew the amount of vegetables that would be equivalent to 12 ounces of vegetable juice. According to Hellawell (n.d) “Apart from preserving intact the vital nutrients contained in fresh fruit and vegetables, juicing also gives an additional advantage over simply eating raw produce. It allows us to obtain the nutrition from raw produce in greater quantities than chewing can achieve.” While looking for articles I came across one on how marijuana plays a role in juicing. Studies have shown that juicing marijuana in raw form can help normalize functions of our bodies.
This is great for people like me who aren’t ready put down the meat. 2. Richard Corliss writes in a Times Magazine article, "Studies shows that consuming more of plant-based foods reduces the risk of chronic diseases. a. Eating more plant-based product will provide great benefits to your health because it contains lower fat and high nutrition.
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.
Generally they are used to make the foods crops more resistant to pests or having more flavour or appearance. Traditionally, modifications were done through breeding, but recently scientists are using genetic engineering to create exact specifications of what they want. For example, geneticists of plants often isolate a gene responsible aimed at drought tolerance and add that gene into another plant. The genes used are not only from plants, but also from other sources also. Bacillus thuringiensis, a natural bacterium, produces crystal proteins lethal to insect larvae.
Breeding plants is the process of selecting plants with the most desirable qualities to produce offspring that inherit these desired traits. Conventional plant breeding genes are mixed and assorted. This results in non-desired traits being inherited together with the trait of interest. It aims to develop improved crop. Crops selected for desirable characteristics that can be reproduced to a variety of needs.
