La gente que tienen menos sangre de lo que deben a tener, tienen anemia.
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.
For agricultural uses. For example: country or area with low precipitation and high droughts will starve if they don't have plants that can survive the harsh conditions such as genetically modified crops being able to take in less water than non genetically modified crops.
C. Mutations may produce new characterists .
You have to understand that MAY is also in the answer, therefore SOMETIMES changes in genetic makeup can happen, but not always.
I hope this helps you!
