Explanation:
The giant landmass described by Wegener in his continental drift hypothesis has broken down into different slabs and they have moved to new positions. The giant landmass is called Pangaea. Pangaea is a supercontinent believed to have produced the continents today.
- The break up of the supercontinent started about 175million years ago.
- Today, it is understood that the concept of plate tectonics provides an insight into how the supercontinent have broken down and migrated to their present position today.
- Plate tectonics also provides a mechanism that provided motion for the plate.
- Wegener from his observation suggested that the continent could easily fit into a single supercontinent like the pieces of a puzzle.
- He also suggested evidence from across the various continents to back up his claim.

Answer: Passive euthanasia
Explanation:
Passive euthanasia is the deliberate termination of the treatment of a terminally ill person by turning off respirators or other life-support machines. Passive euthanasia is when death is brought about by an active doing or by omission. This can be by withdrawing or withholding treatment: Withdrawing treatment: for example, switching off a machine that is keeping a person alive, so that they the person can die of their disease. Withholding treatment: for example, when surgery are not carried that will extend life for a short time.
They do divide! You just don't notice it. Also, some cells can't replicate because it's a major use to your body. They can't get old... For some reason...
