Answer: Wind speed is also important. The rate of erosion caused by a 30-mile-per-hour wind is more than three times that of a 20-mile-per-hour wind. Wind erosion decreases as soil moisture increases. For example, dry soil erodes about one-and-one-third times more than soil with barely enough moisture to keep plants alive.

Answer:
D
Explanation:
Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes). 
 
        
             
        
        
        
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
        
             
        
        
        
The answers are shown below:
In part A: 
             coefficient = 20
             variable = c
             constant = 35 & 23.50
In part B: 
            savings = 20 (3) +23.5+ 35+35+35 +35 +35 +35+35+35+35+35+35+35
            savings = $ 503.5
In part C:
            the new expression will be: 25c + 35 + 23.5
