Document Summary

Part 1: how animals deal with the environment variation from cellular to whole animal level. Microscopes were developed in 1665 by robert hooke by examining cork. Holes in cork were considered cells and that they were the building blocks of life. All organisms are made of either a single cell or an ensemble of cells. A plasma membrane that creates a distinct boundary separating the cell interior from the external environment. The ability to harness materials and energy from the environment. Separate the inside of the cell from the outside. Cell membranes are composed of two lipid layers: Fish can change the structure of their membranes to adjust to their environment. Phospholipid- 2 layers, together are amphipathic a. b. Hydrophilic portion- attracts water, polar (electrons at one end) Hydrophobic portion- consists of fatty acids (carbon chains) i. When a double bond is present, it causes a kink in the chain.
