This is most likely the result of OXIDATION. When an apple is cut open, the cells of the apple are exposed to the atmosphere, the in built defense mechanism inside the apple that is supervised by certain enzymes react to this situation by reacting with oxygen and creating an oxidized brown layer which protects the apple from foreign bodies.

Explanation:
With time bacteria cells increase in number, exponentially. This means with each generation, the population doubles. An example is that if initially there were 2 bacteria, they become 4, then 16, then 32, then 64, 128, then 256...etcetera. Remember bacteria can double their population in very short times. E. Coli cells double in the lab in 15 – 20 minutes.
However, bacteria are also subject to limiting factors that do not allow their cells to double indefinitely, resources such as space and nutrients limiting growth rates for bacteria especially when their numbers exceed the carrying capacity of their environment.

When half of the earth is facing the sun we have daylight.
<u>Explanation:</u>
The earth rotates about its in every 24 hours. When the earth's one of the sides faces the sun, then days occurs. When the side of the earth is far away from the sun, then night occurs. The earth rotates in an anticlockwise direction when we view form the north pole. The daylight sweeps the darkness from east direction to that of the west across the world.
All planes have day and night times because they all rotate about their axis. The day and night cycle time or the length differs for each planet. this is because the speed in which they rotate differs. The planet mars has the same day and night cycle length as earth.
