Why do ribosomes attach to the endoplasmic reticulum
a.) the endoplasmic reticulum provides a greater surface area, thus increasing protein production and secretion
b.)the smooth endoplasmic reticulum packages and transports the proteins made by the ribosomes
c.)the ribosomes store water and the other materials on the endoplasmic reticulum
d.)the ribosomes store proteins that are not used by the endoplasmic reticulum

Hurry which of these is true about index fossils? a) are very scarcely found b) used as guides in relative dating c) found in the youngest layer of the rock d) used as reference points in absolute dating

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.
