BIOL 1201 Lecture : Lectures 1,2,&3 Notes
Document Summary
What is science: understanding the natural world, study of how the world works, understanding and application. 1. 4: organization**: organic matter (very complex, uses energy**: gas exchange, uses resources in environment, development, reproduction*, evolve, respond to the environment** What determines solubility: like dissolves like, solvents with similar properties dissolve in solutions with similar prop, like in term of polarity, polar solvents will dissolve in polar solutions, non-polar solutes dissolve in non-polar solvents. Atom: smallest unit of matter separable by normal chemical means, the smallest unit of matter that retains all of the properties of that element. 8/20/2012 4:11:00 pm: smallest unit of matter separable by normal chemical means, the smallest unit of matter that retains all of the properties of that element. What determines the polarity of a molecule: the types of bonds within a molecule. Chemical bonds: form when atoms gain and lose or share electrons, they are the result of electrical attractions between atoms.
