BIOTECHNOLOGY AND ITS APPLICATIONS Biotechnology is the use of living systems and organisms to develop or make useful products‚ or "any technological application that uses biological systems‚ living organisms or derivatives thereof‚ to make or modify products or processes for specific use. For thousands of years‚ humankind has used biotechnology in agriculture‚ food production‚ and medicine.[2] The term itself is largely believed to have been coined in 1919 by Hungarian engineer Károly Ereky.

There may be just the impressions of footprints or leaf- prints and not the original part of the organism. (iv) Fossils might be also in the form of casts or mould. Conditions favourable for preservation: We know that millions of animals and plants had lived‚ died and were destroyed without leaving a trace. But it has been observed that two factors are favourable for the preservation of organisms as fossils (a) The possession of hard parts such as shells and bones‚ and (b)Quick burials

took place‚ and a lot of it was due to natural selection and how our bodies and traits changed over time to deal with the new challenges faced everyday. According to the New World Encyclopedia "Natural selection is the process by which biological organisms with favorable traits survive and reproduce more successfully

12/16/13 Abstract This experiment was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism ’s traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which

(Verhoef‚ 2010). Krebs (1972) described a community as an assemblage of populations of living organisms in a prescribed area or habitat. However‚ according to Wright (1984)‚ the working definitions of community can be divided into two basic categories: organismic or individualistic. The organismic approach contends that communities have discrete boundaries and that the sum of the species in an area behaves as organism with both structure and function. In contrast‚ the individualistic concept regards communities

What we need is to love without getting tired Jains believe that life exists in various forms in different parts of the universe including earth. Jainism has extensive classification of various living organisms including micro-organisms that live in mud‚ air and water. All living organisms have soul and therefore need to be interacted without causing much harm. There is nothing like a mothers love The

In this sense‚ someone who has had severe head trauma may be classified as brain dead. In this case‚ the body and brain are still functioning on a base level and there is definitely metabolic activity in all of the cells that make up the larger organism‚ but it is presumed that there is no self-awareness so the person is classified as brain dead. On the other end of the spectrum‚ a different criterion for defining life would be the ability to move a genetic blueprint into future generations‚ thereby

Lesson 1 The goal of science is to provide explanations for events in the natural world and to understand patterns in nature to make useful predictions about natural events. Scientific methodology involves observing and asking questions‚ making inferences and forming hypotheses‚ conducting experiments‚ collecting and analyzing data‚ and drawing conclusions. Key Terms 1. Science- organized way of gathering and analyzing evidence about the natural world 2. Observation- the act of noticing and
