What is Included in a Edexcel Biology Paper?

What is Included in a Edexcel Biology Paper?The first topic is on the history of biology, and is probably the easiest part of an Edexcel Biology Paper. You will get three main topics: a review of the main themes in biology, what are the biological theories we have used throughout the ages, and the modern methods of studying nature and society.

When we talk about biological theories, we have to distinguish between traditional and recent theories. Traditionally, biologists studied changes in the environment that occur over time or without human intervention. Modern biologists study organisms that evolve over time and under the influence of humans. It is the emergence of modern man in evolutionary terms, that presents a problem for the 'traditional' view.

Modern medicine is the attempt to solve the challenges posed by evolution and adaptability. This is not the same as the physical sciences. One can say that the study of biology involves studying the structure and function of living things, but it doesn't really go any further than that. Physical science starts with the observation of nature. Biology goes on from there and considers how those physical characteristics function.

Evolution was a very contentious issue during the time of Darwin when scientists asked scientific questions about the causes of species, why some species survived while others did not, and about the interplay between selective pressures on species. However, this has changed over the years as researchers have looked more closely at the natural history of living organisms and have attempted to predict how species will change in the future.

It is surprising to see that the newer techniques have been able to replace the old concepts about the causes of species and their behaviour, and how they are affected by environmental factors. As a result, today scientists refer to a wide range of biological theories and are able to integrate many into one comprehensive and integrated picture. Biologists have also discovered that they are not the only organisms that change.

It took a big step to shift from studying living things and their physical features to studying the biological issues which involve an organism's genetics, hormones, and other elements of its physiology. The evidence for selection acting on genes has led scientists to believe that there are strong selective pressures on the expression of genes and the development of organs and tissues. These considerations indicate that selection on genes is an important part of the evolution of organisms.

Bioengineering is a branch of science in which a person can make plants, animals, and even people from scratch. Bioengineering might have a lot of appeal for the bio-technical industry. The challenges involved in designing and creating a human being, though, have to do with the discovery of the body's structure and how it responds to environmental stimuli.

Bioengineering is at the forefront of current developments in the field of medicine and health care. A new understanding of anatomy and physiology could play a huge role in this field, if this potential is ever fully realized.
