Is manganese dioxide a catalyst?
Enzymes are boilogical catalysts or assistants that speed up chemical reactions with out changing all enzymes are catalysts but not all catalysts are enzymes.Manganese oxide is not an enzyme but is a catalyst it is also a mineral. Thank you.
Which observation would provide indirect evidence that the bubbles are not oxygen?
If the bubbles do not relight a glowing splint, it would suggest they are not oxygen. Oxygen is a gas that supports combustion, so if the bubbles do not allow the splint to reignite, it indicates they are not oxygen.
Can manganese poisoning affect the pancreas and cause death?
I found this, can anyone try and explain if it has anything to do with the question and will it help? Autoradiography of manganese: accumulation and retention in the pancreas. Lyden A, Larsson BS, Lindquist NG. By means of whole-body autoradiography, the general distribution of 54MnCl2 was studied in mice and a Marmoset monkey. High accumulation and retention were observed in the pancreas in both species. Gamma counting experiments in mice after a single intravenous injection of 54MnCl2 showed that the level in the pancreas exceeded that of the liver at all survival times (20 min. - 30 days). Also in the monkey, the concentration in the pancreas exceeded that of the liver, and the pancreas had the highest tissue/liver ratio of the organs measured at 24 hours after injection. The high uptake and long retention in the pancreas suggest that manganese is of importance for the pancreatic function but also that the pancreas may be a target organ for manganese toxicity. Positron tomography, using 11C-labelled amino acids, has been found to be a promising diagnostic technique for the study of pancreatic disease. Positron emitting manganese isotopes may be worth further studies as possible agents for pancreatic imaging.
Who was the first scientist to suggest groupin substances into acids and alkalis?
The first scientist to suggest grouping substances into acids and alkalis was the French chemist Antoine Lavoisier in the 18th century. He categorized these substances based on their chemical properties and reactions.

What do common structures in two different species suggest?
They have a common ancestor they both might have evolved from.
What does 'fluorescent urine' mean?
Fluorescent urine means.......well fluorescent means like glowing and urine means liquid or water. So I suggest it means glowing liquid or something. If you were using markers and if it said fluorescent urine it would mean that the markers are bright and they kind of glow.

When did dolphins appear on earth?
Fossil records suggest that dolphins evolved around 10-15 million years ago during the Miocene epoch. They are believed to have evolved from land-dwelling mammals that returned to the sea.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
