Answer:
The correct option is B. Electrogenic pumps creates a voltage difference across the membrane.
Explanation:
Electrogenic pumps are used to travel molecules in and out of a cell by establishing a concentration gradient. Hence, the statement that best describes the property of electrogenic pumps is B.
Other options, like option A is correct but it does not describe the general property of the electrogenic pump.Option C is incorrect because not a large variety of solutes can pass through the membrane.
Correct answer is;
C) Primordial soup origin
Explanation; I had taken the test on USA test prep

Explanation:
The base unit for time is the second (the other SI units are: meter for length, kilogram for mass, ampere for electric current, kelvin for temperature, candela for luminous intensity, and mole for the amount of substance).
The standard unit of length based on the metric system is a meter (m). we can convert a meter into various units like millimeters (mm), centimeter (cm), and kilometer (km). ... A kilometer (km), meter (m), and centimeter (cm) are the commonly used units of length.
Answer:
This serves to insulate the sea ice, maintaining cold temperatures and delaying ice melt in the summer. After the snow does begin to melt, and because shallow melt ponds have an albedo of approximately 0.4 to 0.5, the surface albedo drops to about 0.75. Albedo drops further as melt ponds grow and deepen.
