If the membrane of a cell were no longer selectively permeable then "The cell would die as it would not be able to regulate which substances could enter and leave", since a selectively permeable membrane allows both things to enter and leave for the cell's survival.

Hello!

So, day and night are caused because the earth makes a full rotation on its axis once every 24 hours.

That way, have of Earth is facing the sun (it is morning on that side) and the other half isn't (which is why it is nighttime over there).

For example, if it's nighttime in Canada and America, it's morning in Pakistan and India. This is because Pakistan and India are facing the sun whilst Canada and America are not.

A N S W E R:

The balls should be moved so that half the Earth is facing the sun and the other half is not. This would be 24 hours. As for the sun, it is a gas, not a solid, so it doesn't rotate like one. However, that does not mean that it is not rotating to some extent.
