To find an average, add all the terms together and then divide them by the number of terms.
7.1 + 9.8 + 2.3 +8.5 + 7.4 + 5.7 = 40.8
40.8/6 = 6.8.
so yes, the answer is b.
Mercury is a barren planet with little atmosphere. In many regards it is similar to our own moon. However, it is also very close to the Sun, so humans will have to set up bases in craters or near the Poles to avoid being blinded.
Answer:
- Microevolution happens at a <u>smaller</u> scale, hence the prefix micro.
- Macroevolution happens at a <u>larger</u> scale, hence the prefix macro.
- Microevolution occurs within a single population or species, over a shorter period of time.
- Macroevolution can occur among multiple species, and takes a longer period of time.
Explanation:
Hope this helps, I really tried to explain this :)
That they are both theories of evolutionary change, but the tempo of the change is different enough that we have the two theories. Rapid evolutionary change punctuated with long periods of stasis describes the former while gradual and incremental change over long periods is the description of the later. Natural selection seems to be more important in gradualism than punctuation, but this is <span>a murky area that is argued about often.</span>
