Final answer:

In a closed system, matter is conserved, and energy can transfer in and out.


Explanation:

The two correct generalizations based on cycles of matter in a closed system are:

  1. The amount of matter within the system remains the same: This is in line with the law of conservation of matter, stating that matter cannot be created or destroyed in a closed system.
  2. Matter and energy can cross the boundaries of the system: While matter remains constant, energy can flow in and out of the system.

Therefore, in a closed system, matter is conserved, and energy can transfer in and out.
