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

Evolution Evolution- change in a population over time Charles Darwin: A Naturalist (type of biologist) Sailed with an explorer on the HMS Beagle to the Galapagos Island in 1831 (22 years old) He observed Turtles: On the island they were huge and had to eat food up high (the neck would extend) over time‚ the shell changed. The ones with the short necks died off because of lack of food Published the book: Origin of Species By Means of Natural Selection (to beat Wallace) He’s Catholic Owen-

Darwin founded a new branch of life science‚ evolutionary biology. Four of his contributions to evolutionary biology are especially important‚ as they held considerable sway beyond that discipline. The first is the nonconstancy of species‚ or the modern conception of evolution itself. The second is the notion of branching evolution‚ implying the common descent of all species of living things on earth from a single unique origin. Many people are familiar with how Darwin came up with the theory of

Energy Conservation - Mitigation Strategies and Solutions Final Project Sherry Howard Axia College of University of Phoenix As the world continues to grow and third world countries continue to industrialize‚ energy consumption has become a growing concern. Every aspect of our daily routines require the use of some sort of energy‚ if it is gas for transportation‚ electricity to heat our homes or a combination used in manufacturing of goods. The majority of energy is generated from nonrenewable

Chondrichthyes were my motivation to get involved and stick with Marine Biology no matter the challenges. Growing up I found comfort in sharks. Due to media and lack of understanding sharks were viewed only as malevolent killing machines. I thought this false‚ constraining label was unjust and unwarranted. Just as sharks had a constraining label I was stereotyped to be at best average when it came to academics. I had a minor learning disability that made reading and writing a major obstacle. After

Kate Rowe Biology 4 10-8-09 Biology Essay: Parts of a Cell Describe the fluid-mosaic model of a plasma membrane. Discuss the role of the membrane in the movement of materials through each of the following processes: a.) Active Transport b.) Passive Transport All living cells contain a plasma membrane‚ which acts a boundary for the cell. The plasma membrane regulates the cell’s chemical composition because it uses selective permeability to allow certain substances to enter or exit the cell
