Four different phylogenetic trees of a group of salamanders have been proposed. trees a and b each require 12 homoplasies, but tree a requires 14 synapomorphies and tree b requires 13 synapomorphies. tree c requires 15 homoplasies and 13 synapomorphies. finally, tree d requires 10 homoplasies and 15 synapomorphies. according to the principle of parsimony, which tree(s) is/are the most accurate? a) tree a only b) tree b only c) tree c only d) tree d only e) both tree a and tree b

All fats are part of a larger group known as lipids. lipids come in a variety of forms in food, including triglycerides, phospholipids, and sterols. choose the statement below that correctly describes the types of lipids found in foods. all fats are part of a larger group known as lipids. lipids come in a variety of forms in food, including triglycerides, phospholipids, and sterols. choose the statement below that correctly describes the types of lipids found in foods. triglycerides contain two fatty acids attached to a glycerol backbone. the body does not manufacture phospholipids, so they must be included in the diet. about 95% of the fat you eat is in the form of sterols. sterols like cholesterol have a ring structure.
