Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
 
        
             
        
        
        
changes of state are physical changes. they occur when matters absorb or loses energy. processes in which matter changes between liquid and solid states are freezing and melting period processes and which matter change between liquid and gases states are vaporization, evaporation, and condensation
 
        
             
        
        
        
Answer: What is the defining characteristic of eukaryotic cells? Put these in your own words.
Eukaryotic cells are defined by the presence of a nucleus containing the DNA genome and bound by a nuclear membrane (or nuclear envelope) composed of two lipid bilayers that regulate transport of materials into and out of the nucleus through nuclear pores.
What types of organisms have eukaryotic cells?
There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
 
        
             
        
        
        
Capillaries are one cell thick and so this makes them very thin. capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area.
        
             
        
        
        
C.Plant cells have a large central vacuole that takes up most of the cell's space, and animal cells have many smaller vacuoles.
Hope it helps : )
