Answer:
B. In horizontal rock layers, each layer is younger than the one below it
Explanation:
Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence. ... It is one of the great general principles of geology..
Answer:
Glycolysis evolved before Kreb's cycle and Electron Transport chain. This view is supported by following facts:
- Glucose cannot enter the mitochondria and it needs to be broken down into pyruvate in the cytosol by the process of glycolysis.
- Pyruvate then forms acetyl CoA that enters the mitochondria where it undergoes Kreb's cycle.
- The Electron transport Chain occurs by passing of electron and finally donating it to the electron acceptor oxygen. The molecules of NADH produced in the preparatory phase of glycolysis provides the electron for electron transport chain.
- Thus Glycolysis must have evolved before Kreb's Cycle and Electron Transport Chain otherwise the raw materials for both the processes would not have been available.
oxygen and air are abiotic
The correct option is B.
Communication between cells can be inter communication or intra communication. Inter communication refers to a type of communication in which message is transfer from a near or distant cell to another cell, while the intra communication form of message transfer is one in which a message is been passed across within a single cell.
In the option B above, a single cell is involved and that is an example of an intra communication. The other options are example of inter communication.
