The hollow impression of a trilobite is an original remains fossil.

The statement is true.
Carbohydrates are broken down in order to obtain glucose for respiration in cells. When there is an inadequate amount of carbohydrates, other macromolecules must be broken down. Excessive breakdown of fats is not possible due to the fact that it causes ketosis; therefore, proteins are broken down and the body starts to lose muscle mass.
No I think you need to do some more research
