What might explain the differences in the Caloric content of the different foods you tested? For example, why did the honeycomb cereal have a different amount of Calories/gram than the pecan? This about this at a molecular level... What might explain the differences in their Caloric content?

i don’t no. suiopgohjk

the fossil record provides evidence of a common ancestor to many species.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
