The correct answer is Mutualism. Mutualism is when each organism benefits from their relationship.
The average speed is
(95 + 55)/5 = 150/5 = 30 kilometers/hour
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
<em>A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.</em>
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.
Microevolution is the answer
