Liuyi Bian P2 1. The physical structure of a protein often reflects and affects its function. (a) Describe THREE types of chemical bonds/interactions found in proteins. For each type‚ describe its role in determining protein structure. Different types of bonds/interactions in proteins lead to different kinds of structures. Three of the most commonly known chemical bonds in proteins include the hydrogen bond‚ the covalent bond‚ and the ionic bond. In hydrogen bonds‚ hydrogen interacts with

Genetically modified organism is one of the least talked about topics in relations to current ongoing problems. For those who don’t know exactly what a genetically modified organism (GMO)‚ a GMO is known as an organism that has been genetically modified this genetic material has been reformed to improve product quality. GMOs are used for many things although the best-known use is for genetically modified foods. According to the World Health Organization “Genetically modified (GM) foods are foods

being on the Earth.(1) They have a huge impact on humans and our activities. They are pests of both food and animals‚ and are responsible for disease transmission. They also create important food sources and are beneficial through processes such as pollination and scavenging. The high degree of insect diversity is due to a combination of high rates of speciation and low rates of extinction.(2) The orders with the highest species richness include Coleoptera (beetles)‚ Hymenoptera (ants‚ wasps and bees)

‘Define Biodiversity and using examples‚ explain why it is important’ Biodiversity is the variety of life on earth. A fuller definition is given in the Convention on Biological Diversity (CBD) from the 1992 Earth summit: ‘Biodiversity is the variability among living organisms from all sources‚ including terrestrial‚ marine‚ and other aquatic ecosystems and the ecological complexes of which they are part ; this includes diversity within species‚ between species and of ecosystems’ (Hambler‚ C.‚ 2004

Natural ecosystem services is split into four categories: provisioning‚ such as the production of food and water; regulating‚ such as the control of climate and disease; supporting‚ such as nutrient cycles and crop pollination; and cultural‚ such as spiritual and recreational benefits. 6.

DEBATE STRUCTURE Overall Argument: Aside from common belief‚ scientists claim that genetically modifying plants is natural‚ and GM crops hold the only hope for feeding the rapidly expanding world population. GM crops can have health benefits‚ they have the potential of helping the world’s poor people‚ and GM technology can help the environment. Genetically modified crops are thoroughly tested for potential risks and have to oblige to highly regulated laws. First Talking Point (A): GM Crops

For DNA transcription terminators‚ see Terminator (genetics). Genetic use restriction technology (GURT)‚ colloquially known as terminator technology or suicide seeds‚ is the name given to proposed methods for restricting the use of genetically modified plants by causing second generation seeds to be sterile. The technology was developed

Old No. 7 Nestled in a quiet mountain glen just outside of Lynchburg Tennessee you’ll find the Jack Daniel’s distillery. Started in 1866 by a man named Jasper Newton Daniel‚ he started distilling a sour mash whiskey now known as Jack Daniel’s. “Using spring water free of iron traces‚ he added the finest white corn‚ the best rye‚ and barley malt‚ both fresh and ripe yeast to make a "sour" mash‚ different from most bourbons.”(sippin’ whiskey) He let it ferment 24 hours longer than ordinary bourbons

are used for growing all kinds of plants‚ including flowers‚ fruits and vegetables. It is often used to grow saplings in the late winter and early spring‚ which are later planted in the open in warmer weather. Pollination of the plants is done naturally‚ by using bees‚ or artificial pollination may be done‚ depending on the requirements. Greenhouses also protect plants from weather phenomena such blizzards or dust storms. Have you ever wondered how does a greenhouse work? The widely spread (and believed)
