1. Describe briefly how genetic engineering has improved agricultural crops. It has allowed humans to create better crops‚ or crops with more desirable characteristics (for example‚ frost resistant strawberries‚ seedless watermelons and oranges‚ combinations of fruits like tangelos and It increases yield and makes crops more resistant to parasites‚ harsh weather‚ and disease. 2. Explain how biotechnology research has affected modern life. Tools such as genetic engineering‚ nanotechnology‚ and

Discovery of New Poison Dart Frog Biologists have discovered a new species of dart frog in the headwaters of the Rio Cano in Panama. This newly found frog has been named Andinobates geminisae after Geminis Vargas. Geminis Vargas is the wife of Marco Ponce who supported him toward the discovery of the new dart frog species. The new dart frog is very small about 12.7 millimeters in length and it is about the same size of a fingernail. Although the new dart frog is very small in size; it contains

America from Europe in the 1600s. They produce honey and pollinate crops. In recent years honeybee populations across the continent have declined by as much as 70 percent. Their loss could effect fruits and vegetables such as apples‚ broccoli‚ strawberries‚ nuts‚ asparagus‚ blueberries and cucumbers. Honeybees pollinate $14 billion worth of seeds and crops in the US every year. Therefore‚ if honeybees disappear‚ they could take most of our insect pollinated plants with them‚ potentially reducing

alcohol. Esters are ubiquitous. Most naturally occurring fats and oils are the fatty acid esters of glycerol. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters‚ such as nitro-glycerine‚ are known for their explosive properties‚ while polyesters are important plastics‚ with monomers linked by ester moieties. ------------------------------------------------- Structure & Bonding

engineering may raise ethnic problems since it involves the use of both animal and plant genes. This may pose a huge problem for vegetarians since animal genes are sometimes used to modify plant genes. For example‚ fish genes are inserted into strawberries to make them resistant to climatic conditions and make them available throughout the year. Vegetarians may be unable to follow their fasting. They might eventually have to go against their own religion and ways. Hence‚ a whole culture would disappear

creating bigger than normal sized strawberries. A question seems to arise‚ is all this technological advancement necessary? Are we as a society taking unnecessary measures to “fix” something that is natural and worked since the beginning of time? In the medical world‚ many health problems have been examined where food and nutrition were identified as partial contributors to the problem. This film helped in explaining how enzymes are used to knick corn DNA and how foreign DNA was then presented into the

formed in the body are highly dangerous‚ as they are unstable molecules with an odd number of electrons. Since they have an odd number of electrons they seek and steal electrons from other molecules in the body‚ causing damage to the cell membranes or DNA in cells‚ leading to destruction of cells and metabolic processes in the body. As the free radicals steal electrons and destroy the healthy cells and stable molecules‚ they cause more free radicals to form. This forms a sort of chain process and can
