If the plant morphs you study are going to respond to natural selection, they much vary in phenotype, and this variation must be heritable. this variation must also result in differences in relative fitness among the morphs. for example, the size of leaves a plant produces could affect relative fitness by determining how much energy a particular plant collects. the amount of energy collected would affect investment in reproduction. leaf size is a measurable trait. below, suggest three other measurable plant traits that could affect relative fitness and explain them briefly.:

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.
