In order to support his theory of evolutionary change, charles darwin concentrated his studies on the many species of finches in the galapagos islands. darwin noted that many of the birds had different shapes and styles of beak. what is a possible explanation for what darwin observed? a) the birds had beaks that were adapted for feeding differently. b) some birds had been injured by predators and were poor competitors. c) people had bred the bird to have beaks with varied shapes and sizes. d) the birds had different beaks because females preferred certain beak shapes over others.

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.

Why is the statement not a hypothesis? sunflowers require soil and plenty of sunlight and water to grow and thrive.
