Answer:this area experienced warming temperatures and significantly reduced rainfall, resulting in the formation of the Sahara Desert.
Explanation: hope this helps <3
 
        
             
        
        
        
First pic :
plants do not have cell membranes
(plants have BOTH cell membranes and cell walls)
second pic:
ATGC
(opposite strand of the DNA TACG)
third pic:
the second choice
(selectively permeable means only specific molecules could get in and go out)
fourth pic:
option 2 
(cellular respiration takes sugar (or food) and makes it into ATP energy. this is what makes us have energy after we eat)
I really hope this helped :))
        
             
        
        
        
Both plants and animals are able to do cellular respiration. Plants convert nutrients from the soil into usable energy. 
This is the plant cellular respiration formula:
oxygen + glucose -> carbon dioxide + water + heat energy
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth
