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

fact that 95% of our sea is unexplored has always fascinated me. We use water in everyday life and without it there would be no life on Earth‚ yet we know so little about it. Both my academic and personal life has developed my interest in marine biology. My interest in wildlife and outdoor work drove me to successfully apply for the post of volunteer assistant at Washington Wetlands centre‚ I started in January 2013 and attend at least once a week.

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

would like to be a marine biologist. During my senior year of high school I applied to Millersville University to pursue a Bachelor of Science in Biology‚ with a concentration in marine biology. Through my undergraduate studies‚ my interest in biological oceanography developed. There are many overlapping aspects of biological oceanography and marine biology that interest me and why I want to pursue a graduate degree in this field. I am particularly interested in marine phytoplankton‚ their role in
