Diffusion is the ability of molecules to follow a concentration gradient, moving from regions of high to low concentration. For small, nonpolar molecules such as O2, CO2, and some narcotics, they are small enough to slip through the phospholipid bilayer of the plasma membrane. Small, polar molecules such as water, are also small enough to slip through, but because of their polar nature, this movement is impeded by a factor of 1000. What about larger molecules like glucose? These molecules are too big to slip through the phospholipid bilayer, regardless of the concentration gradient. Larger molecules require a protein channel for transport across the plasma membrane. Because the movement will be driven by the concentration gradient, this movement is called facilitated diffusion, to indicate that a protein channel is necessary. Both prokaryotic and eukaryotic cells have protein channels for this purpose.
prokaryotic.
A frog is obviously eukaryotic, as all organisms are except for bacteria, which are prokaryotic.
Bacteria and Archaea domains include prokaryotic organisms.Eukarya domain includes Eukaryotic organisms.
Plasmodium vivax is a eukaryotic parasite. Eukaryotic organisms have their genetic material enclosed in a nucleus, while prokaryotic organisms do not have a nucleus.
Monera are prokaryotic organisms. They are single-celled organisms that lack a true nucleus and other membrane-bound organelles.
Eukaryotic cells have a nucleus and other membranebound organells, while prokaryotic cells don't
Multicellular organisms are eukaryotic.

No, but eukaryotic cells contain a descendant of a prokaryotic organism.
Bacteria and Archaea domains include prokaryotic organisms.Eukarya domain includes Eukaryotic organisms.
No most unicelluar organisms are not eukaryotic alot of them are prokaryotic
Linear DNA is typically found in eukaryotic organisms, while prokaryotic organisms usually have circular DNA.

Circular DNA is found in prokaryotic organisms.
All prokaryotic organisms are unicellular. Eukaryotic organisms are multicellular
