include bacteria and archaea. Population evolution in microbial life refers to the change that occurs in the microscopic organism populations over a SC160 Basic Biology Assignment 08 period of time. Evolution of microbial life is used in science and research for researching and studying diseases caused by the evolving microorganisms. This information is used by scientists to research and develop with medications to fight these diseases. Population evolution and microbial life are presented in the following

Microbial growth is a broad idea that represents the study of populations of dividing cells, most often via binary fission, forming identical daughter cells through the replication and division of chromosomes. Prior to the generation of endospores, the measurement of focus in determining microbial growth, the numerous cells that are present go through phases to replicate and become visible. These phases include the lag, log (exponential), stationary, and death, in which the cells grow, reproduce

Chapter 1 notes 1.1 ubiquitous= found everywhere, found in all natural habitats (microbes). Microbiology- is a specialized area of biology that deals with tiny life forms that are not readily observe without magnification. microscopic= small to see. microbes= small life. -Groups of Organisms that we will be studying : bacteria, viruses, funny, protozoa, algae and helminths (parasitic worm) -Microbiology consider the largest and most complex of biological sciences. Here we study the aspects

size and made visible on a gel. Population evolution, the generation-to-generation changes in a population’s frequency of alleles, can be used to estimate the frequency of a harmful allele, which can be useful in dealing with genetic diseases. Three examples of this evolution are genetic drift, gene flow, and natural selection. Genetic drift is a change in the gene pool of a small population due to chance. Gene flow is a genetic exchange with another population, which may add or remove alleles.

use microbial genomics research to create new energy sources (biofuels) and develop environmental monitoring techniques to detect pollutants. Risk Assessment which will assess health damage and risks caused by radiation exposure, including low-dose exposures and exposure to mutagenic chemicals and cancer-causing toxins. Bioarchaeology, Anthropology, Evolution, and Human Migration will help with the study of evolution through germline mutations in lineages, migration of different population groups

existence of flukes and it could also on other worlds also (Des Marais, 2000). The question on when did photosynthesis take its place in the place Earth is an issue which has been researched widely in order to unearth the many unknown mysteries. Probably life is thought to have begun early the history of the Earth, perhaps more than 3800 years ago and through the years it has received a lot of sophistication in terms of metabolism. Great developments of biomolecules and key pathways reveal a great deal

material which do not burden the environment significantly. Biodegradation is necessary for water-soluble or water-immiscible polymers because they eventually enter streams which can neither be recycled nor incinerated. It is important to consider the microbial degradation of natural and synthetic polymers in order to understand what is necessary for biodegradation and the mechanisms involved. This requires understanding of the interactions between materials and microorganisms and the biochemical changes
