Okay, let's see... 
In the center, we have the inner core, then the outer core, and then the slow moving mantle. On the outside, we have the crust a.k.a. where we live. =]
        
                    
             
        
        
        
Answer:
Biogenesis = <u>Life from life</u> : Spontaneous Generation = <u>Life from non-living things</u>
Explanation:
As an accurate statement of the difference between spontaneous generation and biogenesis:
Spontaneous generation that sometimes refers to "abiogenesis" is an idea that life comes from non-living things/components. Whereas biogenesis is a contemporary concept that life can only arise from another living thing. 
Cell division, a baby of mice born from adult males and females, etc. are some examples of biogenesis. In contrast, there is no example of spontaneous generation. It remains a theoretical concept.

Well for starters, they do not have leaves which reduces transpiration. They also grow really long roots that can absorb the smallest traces of moisture in the earth.
        
             
        
        
        
The answer is aerobic. Although cellular respiration can happen anaerobically and aerobically, the question states that it requires oxygen. Therefore, it is aerobic.
