Explain why museums generally mount casts of dinosaur fossils for display, rather than the real specimens. Give three reasons, at least two of which are related to fossil preservation

1. They keep casts to preserve the real fossils.

2. Maybe someone would steal a fossil and sell it on the dark web?

3. They keep casts to keep the real fossils in prime condition, by that I mean like undamaged.

1- dilate

2- perfusion

Explanation

when blood pressure increase the arterioles dilate (become smaller) so that cells can absorb the oxygen from the blood easily. perfusion will be altered or slowed down. (The perfusion is the passage of fluid through the circulatory system. )
