-Homeostasis:maintains stable internal conditions
-Metabolism:cellular respiration
-Growth:biosynthesis
-Made of cells:mitosis and differentiation
-Responds to changes in environment:plant bending towards light
When charged particles from the sun strike atoms in earth's atmosphere, it causes electrons to move to a higher energy state. When the electrons drop back to a low energy state they release light photons. This is what causes the Aurora lights
The answer would be:
Cilium
<u>Here is more about the structures of prokaryotic cells:</u>
Axial filament is a bundle of flagella that are wrapped around the cell's body.
Flagellum is what the prokaryotic cell has that is whip-like in structure. It helps with the motility of the cell.
Pilus is a hair-like structure that are found on the surface of prokaryotic cells. They help the cell attach itself to surfaces.
Peritrichous flagella are several flagella that can be found all over some prokaryotic cells.
Is there a picture that goes with this or a question?
I guess that is:
Within the capillaries of the lungs, gases are exchanged by diffusion; O2 diffuses from the alveolus to the bloodstream and CO2 diffuses from the bloodstream to the alveolus.
