Any fat. Like oil. Fats are hydrophobic, so they resist water and don't mix.
Most likely ATP next time put the answer choices in for multiple choice questions.
D. Polar regions receive less solar energy and heat per unit area than tropical regions
Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.
The greatest cause of the worldwide loss of species is human activity. I think
