134) Osmolarity/Osmotic concentration? Answer: Total concentration of solutes. _______________________
135) Osmotic pressure: Answer: The measure of the tendency of water to move across a membrane. It can be measured as the force required to stop osmotic flow.
136) What is Tonicity: Answer How the solute concentration of a solution affects a cell.
137) What is an Isotonic solution: Answer: Same solute concentration. Passive
138) What is a Hypotonic solution: Answer: Low concentration. More in than out.
139) What is a Hypertonic solution: Answer More out than in.
140) Lyse: Answer: Cell swells and might burst.
141) Crenation: Answer: Cell shrinkage.
142) Facilitated diffusion: Answer: Integral protein carrier on the cell membrane must bind the solute to transfer it through the cell membrane. Substances are still moving down a concentration gradient (no ATP, Passive). Substances that use this method are insoluble to lipids and too large to fit through the membrane.

148) Pinocytosis: Answer: Pino-Drinking. The cell folds the membrane inward to take in a large volume of extracellular materials. Not as specific as receptor mediated endocytosis.
149) Phagocytosis: Answer: Phago-Eating(solid). Only performed by select cells such as macrophages. Cytoplasmic extension called pseudopodia surrounds an object and engulfs it. More specific.
150) Exocytosis: Answer: A vesicle created inside the cell fuses with the membrane to discharge its components out into the ECF. Example; saliva, sweat, neurotransmitters, digestive hormones, enzymes, etc.
Answer: G1 (first gap phase.) S (Synthesis phase). G2 (Second gap phase.)
152) G1 phase
Answer: Cell spends most of its life. The length of time varies depending upon the cell type. Normal cell activities are performed such as growth and protein synthesis.
153) S phase
Another pair of centrioles is manufactured. DNA replication occurs.
154) G2 Phase
Answer: Short phase prior to actual division of DNA. Enzymes needed for division are manufactured. Success of DNA replication is assessed. Errors can be corrected before proceeding. (DNA Mutation)
Answer: Chromatin condenses; chromosomes become visible. Nuclear envelope breaks down. Pairs of centrioles migrate to opposite ends of the cell.
Answer: Chromosomes are present at the equator. Mitotic spindle is fully formed.
Answer: Centromere breaks apart. Each chromatid (now called daughter chromosome) is pulled to opposite poles as motor proteins in the kinetochore break down the spindle fibers.
Answer: Telo=End. Chromosomes reach opposite poles. Rough ER manufacturers 2 new nuclear envelopes. Chromosomes uncoil into chromatin. Mitotic spindle breaks down and disappears. Nucleoli appear signaling the production of RNA to assist with protein synthesis.
Answer: Division of the cytoplasm. Cleavage furrow created as motor proteins interact with cytoskeletal components.
160) When cells divide too rapidly
Answer: Cancer develops.
Answer: Cells create a tumor that can travel to other locations in the body.
