Theories of Biology University of Phoenix – Axia There are seven major theories of Biology that attempt to organize and make sense of the multitude of ideas surrounding the major theories of Biology. The theories include evolution of natural selection‚ inheritance‚ cells‚ biological classification‚ bioenergetics‚ homeostasis‚ and ecosystems. The evolution of natural selection is the theory the theory that attempts to explain how and why species are able to adapt to their environments

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

Marine biology is more than the scientific study of marine life. Marine biology is the study of marine organisms‚ their behaviors‚ and interactions with the environment. Marine biologists study oceanography and the associated fields of chemical‚ physical‚ and geological oceanography. Marine biologists are also able to specialize in large aquatic animals‚ all the way down to microscopic and minuscule organisms. Anything else in between‚ marine biologists are able to study. Marine biology is known

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them
