length by 0.5-0.8 µm in diameter)‚ present in food or water (raw shellfish‚ uncooked fruits and vegetables‚ and other foods). The disease is most common in places with poor sanitation‚ crowding‚ war‚ and famine. Transmission: (reference 1) When humans ingest cholera bacteria‚ they may not become sick themselves‚ but they still pass the bacteria in other ways such as contaminating food or water supplies‚ which can serve as ideal breeding grounds for the cholera bacteria. Cholera usually isn’t transmitted

AP biology FRQ Courtney DeMane 1.22.13 block 7 A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino‚ carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure‚ there are 4 levels. The first one being the primary level. These are made

AP Biology: Chapter 13 - Meiosis and Sexual Life Cycles Overview * The transmission of traits from one generation to the next is called inheritance‚ or heredity * Along with inherited similarity there is also variation * Genetics is the scientific study of heredity and hereditary variation I. 13.1 Offspring Acquire Genes from Parents By Inheriting Chromosomes A. Inheritance of Genes * Parents endow their offspring with coded information in the form of hereditary units

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:

Biomolecules - Biology Unit 3 What is a Biomolecule? Organic molecule made by living organisms Organic Molecules: contain carbon considered the “chemicals of life” Inorganic Molecules: Do not contain carbon Consist mostly of: carbon (c)‚ hydrogen (h)‚ oxygen (o) Monomers vs. Polymers Monomers: single-molecule that may react with similar molecules to form a chain Polymers: a chain of many monomers that are chemically bonded together
