Answer:
C.
Explanation:
A reasonable deduction for Devon could be that while the authors refer to a "relationship," this terminology doesn’t automatically imply a causal link. In numerous scientific writings, the word "relationship" signifies the connections within a system, which may hold equal or even greater significance than the individual components. Conversely, in various other studies, this same wording might be utilized to indicate causation.
Response:
The accurate responses are A and D
To clarify:
Russell's theory involves the natural gradients of protons, asserting that four billion years ago, alkaline solutions emerged, leading to slightly acidic oceans (with CO2 levels being approximately a thousand times higher, reacting with H2O to form carbonic acid which results in mildly acidic seas). Acidity signifies proton concentration levels, higher in oceans compared to vent fluids. This variation has resulted in a natural proton gradient across the vent membranes that favored an outside positive polarity, which resembles the electrochemical potential in contemporary cells. This potentially explains why the last universal common ancestors across the three biological domains developed proton pumps.
The cells capable of dividing into neurons or glia, but which are not classified as either, are termed NEURAL STEM CELLS.
