Living Organisms Research Papers Samples For Students

Introduction

Biotechnology is a field of biology that involves the use of living organisms and biological processes in engineering, medicine and other fields which require bioproducts. Biotechnology utilizes these products for manufacturing. This concept encompasses a wide range of processes which modifies living organisms. According to the UN convection on biological diversity, biotechnology is any technological application which uses biological systems or living organisms to make or modify products for specific use.

DNA profiling on the other hand is a technique that is majorly used by forensic scientists and other criminal investigations agencies to identify criminals based on the information found in their ...

Homeostasis refers to any self-regulating process by which biological systems attempt to maintain stability despite changes in the external and internal environment (Sturmberg & Martin, 2013). Biological systems interact with each other to maintain a suitable condition of the internal environment for the survival of the living organism. The biological systems of the living organism are in a state of constant change.
The regulation of the systems within a given range of various conditions helps to keep the living organisms alive and healthy. The systems also interact with the external environment in different ways. The conditions of the external environment ...

Introduction

Air pollution is defined as the introduction of biological molecules, particulates, and other harmful substances into the air in sufficient quantities such that they cause damage to the health of living organisms including human beings, plants, and animals and may sometimes cause death. These pollutants may also cause harm to property resulting in corrosion of buildings and causing them to crumble or destroy the environment by introducing foul odors and reducing visibility.
Two different types of air pollution exist: natural or artificial, depending on the causative factors. Air pollutants are also classified into primary and secondary sources. Primary sources ...

Background

Early scientists and nutritionists believed that the most vital nutrient in living organisms, for building and maintaining the body was the protein. The role of proteins as enzymes came into existence several years later. This was around 1926 when experiments showed that enzymes were proteins. Insulin was the first protein to be sequenced. Hemoglobin was the first structure of proteins to be resolved. Myoglobin was then resolved later.

X-ray diffraction analysis (X-ray crystallography) led to the determination of the structure of the proteins (three-dimensional structure). The purification of proteins can be made possible from cellular compounds. Several methods have ...
