Answer: New research shows that colonies of Escherichia coli can demonstrate a form of learning.
Explanation: Bacterial colonies can evolve the ability to anticipate changes in their immediate environment, say researchers led by Saeed Tavazoie at Princeton University in New Jersey. Other types of bacteria could too. This skill could give them the edge over other bacteria that merely adapt themselves to current conditions.
The answer to the question above is a cell.
Answer: Ligand gated channel
Explanation:
Ligand gated channel is an essential membrane protein that has pores and allows the passage of specific ions across the plasma membrane when it is activated by a specific chemical . Examples of such ions that pass through Ligand gated channels are Sodium ions, Potassium ions, Calcium ions. Ligand gated channels are found in extensions of the nerve cells.
Well, the range is more limited. Let's say if you tried listening to Denver radio all the way in Texas, you wouldn't be able to listen to it.
Another one is that other electromagnetic waves with similar frequencies can interfere with each other
