In order to turn percent to a fraction, first, we write it as 48/100. Then, from there we simplify it to the simplest form.
48/100 = (48/4) / (100/4) = 12/25
So, 48% <span>expressed as a fraction in simplest form is 12/25.</span>
        
                    
             
        
        
        
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

Answer:
1. Protein - build lean muscle and strengthen tendons
2. Lipids - insulation and long-term energy
3. Carbohydrates - provides quick, easily digested energy
4. Nucleic Acids - repair and replicate DNA and RNA
Explanation:
a. Think of protein as what helps your muscles grow and strengthen
b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)
c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons. 
d. nucleic acids -  think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.
