r Marine Biology is the study of ocean animals. Biology means is the study of life and marine means water. A marine biologist studies biology and chemistry. Marine biochemist studies biologically active compounds found in the ocean which are useful in medicine‚ or the genetics of marine species. The chemical properties of the ocean are important to understand because the marine environment supports the greatest abundance of life on earth. (http://marinebio.org/oceans/ocean-chemistry.asp) As

Biology Digestion IA 13/03/2013 Jason Gao Rationale: Digestion is the chemical breakdown of food into smaller components that are more easily absorbed. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. When food enters into stomach‚ gastric juice starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. The pH value of hydrochloric in the stomach

Matthew Nims Biology Honors Reflection 2nd nine weeks Period: 2 In this honors portfolio we created models of the cell cycle and used those models to create an animation. The purpose of this is to‚ first‚ memorize the visuals of the cell cycle. The Second is to understand what’s going on in the visuals by creating commentary to describe the changes from stage to stage. The third is to repeat the first and second by critiquing other videos. We used our understanding of mitosis that we

Evolution Unit: Objectives AP Biology Upon the completion of the textbook readings in Chapters 22-26 you should be able to: Chapter 22 1. Explain how the principle of gradualism and Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution. The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection

Marine Biology The field of marine biology‚ the study of organisms within their environment of an ocean‚ lake‚ or river‚ has a very broad range of occupations. Marine biologists try to discover how organisms grow and develop‚ how they get food‚ how their bodies function‚ and how their life relations correspond to other organisms. They also use laboratory experiments to increase knowledge of human life processes. This is a great career for me to enter because there are so many opportunities to
