Answer:
A.) the phospholipid heads can interact with water inside and outside the cell
Explanation:
Phospholipid heads are hydrophilic - they are attracted to water. The tails are hydrophobic - they repel water. In the lipid bilayer arrangement - the heads interact with the water inside and outside of the cell, whereas the tails cluster together to avoid the water. These properties are what create the lipid bilayer arrangement which creates a selectively permeable membrane.

Answer:
An active transport requires energy, a passive transport does not.
That's all! Hope that helps :)
C. The uneven heated of Earth's different surfaces. For e.g., land changes temperatures quicker as compared to the sea.
When the sun comes up, the land heats up quicker than the sea. As a result, air above the land will also heat up more than air above the sea. As hotter air rises from the land, the cooler air travels to the space which the hotter air rose from. This creates wind, or a cycle of air currents.
Hope this helps! :)
P.S. By the way, this seems to be more so of Geography as compared to Biology. :) No worries though!
