Sort the descriptions into properties that describe saturated phospholipids or unsaturated phospholipids.-fatty acid tails pack tightly together-produce a fairly inflexible membrane at a low temperature-have bent fatty acid tails-have at least one double bond in the fatty acid tails-maintain some space between adjacent phospholipids-allow the membrane to remain fluid and flexible at low temperatures-fatty acid tails are straight-have no double bonds in their fatty acid carbon chains

Which pattern most likely came from a gunshot and which one was produced from a blow on the head? explain your answer?

Development of new communities in disturbed environments, such as a burned or a clear cut forest, is called

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
