[A]: against


[Q]: Process:  -A red giant burns mass -This mass creates high core temperatures -The mass decreases -The red giant can no longer fuse the carbon and oxygen in its center -The gravity of the star can no longer hold the outside layers -The layers break away -Only the inner core remains -This inner core is known as a white dwarf.
 Question: What is the effect of there is no more carbon to burn on the mass of the sun is smaller.?

[Q]: Process:  -Bees find a place for the hive, such as a rock crevice or tree branch -Bees gather nectar from flowers -The bees evaporate the nectar by passing it back and forth to each other -The evaporation turns the nectar into sugary honey -The bees chew the honey until it turns into moldable wax -The bees mold the wax into hexagonal (six sided) cylinders -Thousands of these hexagonal cylinders put together form the hive -
 Question: What is the effect of needing less ice cubes on flowers are producing less nectar.?
[A]:
none
