| How are folds advantageous to mitochondria? | They allow a greater amount of electron transport chain enzymes and ATP into the mitochondria. |
| 4 structures that are in all cells? | -plasma membrane -cytoplasm - ribosomes -DNA |
| homeostasis? | It balences the body systems for it to function. |
