Pls help if u know Shannon wants to investigate how erosion happens along shorelines. She researches the topic and learns that events such as high winds and rough waves during a storm can cause sand to more quickly wash away from beaches. Shannon decides to investigate more by conducting systematic observations. Which plan would help Shannon investigate erosion using systematic observation?

collecting shells from different beaches and arranging them in size order

photographing and comparing the sand at beaches before and after storms

Creating a model shoreline, changing wind speeds, and measuring changes in the sand

Using a hoess with different amounts of force spray sand and studying the differences

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.
