Answer: sunlight
Explanation:
They get carbon dioxide from the sunlight, in a process called photosynthesis. They absorb the sunlight and turn the energy into carbon dioxide.
Answer:
The correct answer is b the magnitude of the concentration gradient of the molecule.
Explanation:
Dffusion is one of most important membrane transport process that allow several molecules such as gases oxygen and carbon dioxide to pass directly across the plasma membrane.The is no involvement of carrier proteins or ion channels during passive diffusion.
During passive diffusion molecules are transported along their concentration gradient that means from the region of high concentration to region of low concentration,until the concentration of both regions become same.
Hey there,
Your question states: Why is ice less dense than liquid water?
There reason why Ice is less dense than liquid is because ice has compact molecules that are tight together and they stay still. But as for water, those molecules are lose and they are more free than ice.
Hope this helps.
