The diagram represents three sections of a cell membrane showing three different methods involved in the transport of various molecules across the membrane. 1.) Explain why Methods A and B are examples of passive transport

2.) Using information from the diagram, state one reason why the movement of molecules in method C represents active transport

3.) For method A, give one possible molecule that uses this transport method. ALSO, state what specific transport method is taking place for this particular molecule

What causes the phospholipids to organize themselves the way they do

What are they five steps of cloning?

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
