Answer:
The process shown in the model requires energy from the cell.
Explanation:
Active transport refers to the movement of materials across the cell membrane against concentration gradient.
The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
Dark Stage.
At the light stage, sunlight is absorbed by the chlorophyll to be converted into Chemical energy.
Water will be broken down into H+ ions and OH- ions in the presence of light.
At dark stage, sugars are synthesised from carbon dioxide.
A mouse has a greater ratio of surface area rather than a hippopotamus.
