explain the movement of tectonic plates?! - Sea floor spreading in movement of tectonic plates is called divergent‚ the separation of two plate. This can be proved because magma comes out from the fault of ridge which means plate has open and it’s realising the magma. Other reason‚ if diverging is happening at one point‚ that means converging is happening at other end of plate‚ for example Himalayan mountain range at India and Nepal (converging) and other side of plate that contains India is having

the microorganism was identified as Enterbacteriaceae Enterobacter aerogenes. INTRODUCTION Microbiology is a specialized area of biology that places an emphasis on microorganisms. Several microorganisms are included in this subject‚ such as bacteria‚ fungi‚ algae and protozoa. The most important fact that should come out of microbiology is the “profound influence” that microorganisms have on the aspects of earth (Cowan‚ 2012). The objective of this project was

SCOPE OF MICROBIOLOGY: What is Microbiology? | � Microbiology is the study of microorganisms� Microorganisms‚ roughly‚ are living things that are too small to be seen with the naked eye� Microorganisms cannot be distinguished phylogenetically from �macroorganisms� (see variety of microorganisms‚ below)� Microbiology is more a collection of techniques: aseptic technique‚ pure culture technique‚ microscopic observation of whole organisms‚ etc.� Microbiologists

Chapter 1: The Main Themes of Microbiology What is Microbiology? • micron = small and biologia = study of living things • Microbiology = study of small living things • How small is “small”? • What do we really mean by living? • Working definition: Study of entities too small to be seen with the unaided human eye. • (< 0.2 mm = 200 µm = 200‚000 nm) Types of Microbes Prokaryotes include Bacteria and Archaea Eukaryotes include Protista (Algae and Protozoa)‚ Fungi‚ and Animalia

Importance of Microbiology| in Nursing Agriculture Pharmacy Advertisement Microbiology is a subject dealing with microbes and related concepts. Microbiology has come a long way since discovery of microbes and is presently of great help to mankind. It is used in health care‚ food production‚ diagnosis‚ production of alcohol‚ maintenance of sterility and cleanliness etc. Though the subject was initially limited to study of microbes and their characteristics or properties‚ latter it was explored to

Microbiology is the study of living organisms that are too small to be clearly seen by the unaided eye. The science of Microbiology dates back only to 200 years‚ yet the recent discovery of Mycobacterium tuberculosis DNA in 3000 year old Egyptian mummy reminds us that microbes have been around for much longer. Infact‚ Bacterial ancestors were the first living things to appear on Earth. The First observations: One of the most important discoveries in the history of Microbiology occurred in 1665

kingdom of microorganisms was brought into life 3 billion years ago. Since then «the earth is a fundamentally a microbial planet‚ to which the micro-organisms are recent the relatively unimportant additions» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular. They first have been studied by Anton van Leeuwenhoek by the use of his own design microscope‚ in 1675. However

Constructive boundaries occur when two plates move apart which causes new oceanic crust to be formed and mid-ocean ridges are created by the build-up of molten rock on the seafloor due to the mantle building up. This new crust pushes the old crust aside and forcing the plates apart at a very slow rate. Basaltic lava rises which means new crust is being added continuously. Rift valleys are formed at constructive boundaries‚ where convection current causes the crust to be pulled apart causing fractures
