Two atoms come together to form a molecule.
I hope that this has satisfied you.
Answer and Explanation:
Chemo-taxis in pollen grains
- this enables fertilization to take place
Positive rheotaxis in butterfly
-this behaviour leads them to hold their position in a stream rather than being swept downstream.
Positive aerotaxis to aerobic bacteria- enables the bacteria to move from an area of low to one of high oxygen concentration.
