Acertain single ion channel is selectively permeable to k+ and has a resistance of 1.15 gω , therefore a current of potassium ions through the channel is possible. during an experiment, the channel is open for approximately 1.50 ms while the voltage across the channel is maintained at 81.5 mv . how many k+ ions travel through the channel during this time?

the average speed is 24.57 km/hr

b.

explanation:

10.0

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
