emulsifies large fat molecules into smaller ones , providing a larger surface area for lipase to act upon, and neutralises stomach acid and produces an optimum alkaline solution in the small intestine for lipase to act upon

It can cause side effects and the body/immune system is weaker so it's easier to get an infection/disease.

negative pressure system, a vaccum causes the thorax to expand and air to be sucked in, then the vaccum is released and the thorax relaxes and ribcage moves inwards and then you exhale, now I think they just mechanically force the air into your lungs using a tube.

early organisms were soft bodied so their skin decayed, and fossils may have been destroyed by geological activities.

Because many organisms that were around millions of years ago were soft bodied so have decayed and fossils that were around had been destroyed by geological activity, causing a lack/ loss of fossils.
