Answer:
Explanation:
An organ is a group of different tissues that work together to do a particular job. Organs are grouped together into organ systems. Examples of organ systems include the circulatory system and the digestive system. The human body is made up of many cells, so it is an example of a multicellular organism.
I would conclude that Region 1 is an older portion of the surface than region 2.
The amount of clatering is usually an indication of the age of a geological surface; the more craters, the older the surface, because if the surface is young there hasn't been time for many craters to form. Therefore, Earth has a relatively young surface because it has few craters. This is because the Earth is geologically active, with plate tectonics and erosion having obliterated most craters from an earlier epoch. The surface of the moon on the other hand is much older with much more clatering. Additionally, different parts of the moon exhibit different amounts of clatering and thus are of different ages.
The answer is True.
