Answer: The answer is D: to allow maximum exposure to light and to reduce shading of lower leaves. 
Explanation:
The arrangement of leaves on a Stem is known as Phyllotaxy. It is used to enable them obtain maximum exposure to sunlight.
Leaves are classified as either alternate, spiral or opposite. 
Leaves with alternate pattern arise at a different point (node) on the stem. This helps reduce shading of the lower leaves. 
 
        
             
        
        
        
Answer:
A) cyclic and predictable
Explanation:
The graph shows changes in the water levels (in feet, ft). The water cycle consists of water that evaporates from the surface (land and sea) and subsequently returns in form of rain and/or snow. In general, water levels may be unpredictable in short term but predictable in the long term. The graph shows that this process is cyclic because it is regularly patterned and also occurs in regular intervals (therefore being predictable).
