system or muscles. A person’s body is made up of trillions of cells. Animal-like cells differ from plant-like cells. An animal-like cell could be a tiny microorganism or a nerve cell. Plant cells differ because they have protective structures with walls. Each organism has its own unique cell. People have hundreds of cells that are used to do different things in our bodies. All cells are surrounded by a membrane. Animals, people and insects have a nervous system. Some of the systems are more complex

bacteria cell has no nucleus while the amoeba has a nucleus. 15) Length = 4.9x10-2mm or 0.049microns Width= 1.8x 10^ -3mm or 0.018microns 16) The elodea cells look shrunken in the salt solution. The cell membrane pulls away from the cell wall and are smaller in size. 17) The elodea cells loose water in the when placed in the salt solution. Water diffuses out of the cell to the environment which has a higher solute concentration. The appearance changes because the cells undergo plamolysis

bacteria. Bacteria that stain purple are considered gram-positive and bacteria that stain pink are considered gram-negative. B. What is the difference between gram-positive and gram-negative cell walls? Gram-positive cell walls are thick and have many interconnecting layers of peptidoglycan. Gram-negative cell walls are thin and have only one layer of peptidoglycans that are two or three layers thick. C. What is the purpose of crystal violet in the Gram’s stain procedure? The crystal violet increases

IncorrectQuestion 1 0 / 1 pts Which of these is an example of homeostasis? Hummingbirds prefer to feed on nectar from red flowers. Homeostasis is the maintenance of the body's internal state within a relatively narrow range. When the dog's body temperature becomes too high, the animal feels hot. He opens his mouth, lets his tongue loll out, and pants until he feels comfortable again. A shark can detect even minute quantities of blood in the water. Venomous coral snakes and harmless
