BSC 101 Lecture Notes - Lecture 3: Endoplasmic Reticulum, Golgi Apparatus, Covalent Bond
Document Summary
Section 1. 1: aspects of biology applied to the blue whale: body structure, reproduction, ecology. Section 1. 3a: atoms, molecules, and macromolecules in depth. Atoms: all living things are composed of chemical elements, elements: substances that cannot be broken down into simpler substances. These notes represent a detailed interpretation of the professor"s lecture. Gradebuddy is best used as a supplement to your own notes, not as a substitute: the atoms that make up each element have a unique chemical identity based on the number and the arrangements of subatomic particles. Neutrons do not carry a charge: ions are atoms with a charge imbalance (more protons than there are electrons or more electrons than there are protons) Molecules: two or more atoms interacting or bonding together, there are three types of bonds . Covalent bonds strong bonds where atoms share two electrons. Ionic bonds weak bonds bonded together by opposite charges (one positive charge and one negative charge)
