Answer:
The correct answer is both involve moving substance across the membrane.
Explanation:
Passive transport is one of the most important membrane transport process which helps in transport of polar molecules and gases along their concentration gradient across the plasma membrane.No addition energy is required to carry out passive transport because during passive transport molecules move from high concentration region to the region of low concentration.
Active transport is a specific type of membrane transport process which helps in the passage of ions against their concentration gradient across the plasma membrane.As the ions are moving against their concentration gradient additional chemical energy is required to carry out their uphill transport.
The answer is A. Pollutant
One thing that would take place when considering population growth would be the fact of how many people would inherit the country or the city or town of a specific place. For example, where I live, the population would the be "<span>59,087" which would then indicate how largely and the amount if people would be inheriting the city; etc.</span>
