The family of L- glutamate come from the cetoglutarate compound from the Kreps cycle. The family of L-serine, come from 3 - phosphoglicerate compound from the glucolisis. The L - aspartate family, that come from oxaloacetate compound, from the Krebs cylce. The piruvate family that come from the piruvate, from the glucolisis. The aromatic aminoacids, that come from eritrose - 4 - phosphate, from the pentose cycle. And the L histidine family, that come from the ATP.
Answer:a positive feedback

Hi There!
Question:
Which statements indicate what the fossil record suggests about evolution on Earth? Check all that apply.
Answer:
Organisms originally lived only in Earth’s water.
Plants did not have flowers when dinosaurs existed.
Why:
Plants existed when dinosaurs did but they didn't have any flowers, because flowers came along way after plants existed. When earth was form you see that it says earliest waters so that would have meant the first organism brought to earth were organisms that lived in the water.
Hope This Helps :)
One goal of science that is not evident would be option C. To establish a collection of unchanging truths.
