Answer:A large number of autotrophic bacteria—bacteria that produce their own food—live near hydrothermal vents and submarine volcanoes.
These bacteria are considered chemosynthetic, meaning they produce food from chemical reactions usually involving carbon dioxide, oxygen, or hydrogen
If each atom of element D has 3 mass units and each atom of element E has 5 mass units, a molecule composed ..... The electron configuration for the carbon atom (c) is 1s2 2s2 2p2.
Atoms of the element beryllium would most likely behave similar to the way d lithium behaves
The answer is; relative dating
Through relative dating, rock layers are able to be sequenced with regards to their ages relative to each other. This, therefore, does not determine the absolute age of the rock layers (absolute dating). Techniques used in relative dating include stratigraphy and biostratigraphy that determine which layer is older than the other. In absolute dating, methods employed are carbon-dating and radiometric dating.
