Answer:
The concentration gradient is the driving force.
Explanation:
Passive transport of substance occurs when they are moved from the region of their higher concentration to that of their lower concentration. The concentration gradient is the difference in the concentration of substances between two regions or across the membrane. The concentration gradient of substances drives their passive movement. The passive movement of substances does not use metabolic energy. Simple diffusion and facilitated diffusion are two examples of this transport.
I would say the scientific method?
Archea can live in extreme environments; Eubacteria cannot.
and
The gene sequences of their rRNA are very different.
Yes! This is because of the law of thermodynamics which suggests that as energy is transferred or relayed into other forms of energy, entropy increases. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
