Chapter 5: Electrons In Atoms A. Models of the atom i. The Development of Atomic Models Protons and neutrons make up a nucleus surrounded by electrons Rutherford’s model or theory ( figured electrons move around the nucleus) His theory didn’t explain why metals or compounds of medals give off characteristics of colors when heated. Also didn’t explain why the atomic model could not explain the chemical properties of elements ii. The Bhor Model Bohr proposed that an electron is found in specific

Mitochondria is a double membrane bound organelle in charge of energy production. Mitochondria have their own DNA and manufacture their own ribosomes. They produce mitochondrial DNA and nuclear DNA. Mitochondria can be considered a dynamic organelle because their core function is ATP production. Mitochondria produce about ninety percent of the body’s energy. They migrate within the cells and continuously divide and fuse with each other (Santos‚ 2010). They are responsible for producing energy to

Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes

friction is much weaker than sliding friction. • How did they come to be? The wheel was invented in prehistoric times; as the oldest example of a wheel yet found is from the region of Mesopotamia (Iraq)‚ so it may have been invented around the area where Iraq is today. The wheel may have been inspired by a simple observation of a rolling tree trunk‚ as the first wheels were indeed tree trunks. The next development was to use slices of these trunks joined together through an axle. Later‚ these wheels
