Archaea is considered to be another domain, besides Prokaryotes (which include bacteria) and eukaryotes (which include plants, animals, fungi and protests). Eukaryotes have a well-defined nucleus, membrane cell structure. On the other hand prokaryotes have a well-defined cell wall and contain an irregular nucleus. Archaea …
All living creatures are classified by a seven-level system. The top level is kingdom, followed by phylum, and then class. In this particular case, the system is animalia, chordata, and the mammalia, or mammals. Mammals are animals which are warm-blooded, have fur, and live young. …
It nas been proposed initially by ( ) that the individuals with more training experience have additional cardiac output, and such individuals are able to operate with even less oxygen saturation. It is also argued that, in elite athletes, decreased transportation time of the RBCs …
FlyLab will allow you to play the role of a research geneticist. You will use FlyLab to study important introductory principles of genetics by developing hypotheses and designing and conducting matings between fruit flies with different mutations that you have selected. Once you have examined …
Plant Responses Tropism Plant Responses Tropism is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the species. The word tropism comes from …

Introduction Phylogenetics is concerned with the study of evolutionary relatedness between species, populations and groups of organisms. The essential idea in phylogenetics is that all of the organisms on earth are derived from one single common ancestor. Phylogenetics is also involved in the production of …
1. Your case study will begin by looking up and writing a solid, detailed definition of: BIO-MAGNIFICATION. In order to understand the ethical dilemmas that corporations are facing we must look at some of the more obvious areas to the public: polluted water supplies, polluted …
Biology is defined as the study of life while psychology examines the human mind and its processes, especially those affecting behavior. Biological perspective links biology and psychology by focusing on the analysis of human behavior based on biological and physical evidence.
Why is biology important? As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.
Chemical biology deals with how chemistry can be applied to solve biological problems while biochemistry is the study of the chemistry of biology. In general, the chemical biology major focuses on small molecules while the biochemistry major focuses on proteins and nucleic acids.
