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.
Renal glucose reabsorption.
This bacterium would fall into the nitrogen-fixing category. Nitrogen-fixing bacteria thrive in the soil and associate with legumes like clover, converting atmospheric nitrogen into an inorganic form that plants can utilize for growth.
Cuando el agua es abundante (no limita), las plantas tienen la capacidad de poseer más estomas, lo que aumenta el acceso al agua (y a los iones de hidrógeno necesarios) y proporciona un mejor soporte a los tejidos herbáceos.
Espero que esta respuesta sea correcta :)
