<u>Answer:</u>  They have the maximum number of hydrogen atoms.
<em>Saturated fatty acids have the maximum number of hydrogen atoms.</em>
<u>Explanation:</u>
A fatty acid that doesn’t contain any double bond between carbons in their molecular structure is known as saturated fatty acid. They are also incapable of absorbing hydrogen in their molecular structure thus the name. 
Saturated fatty acids are generally found in animal fats like butter, milk and dairy products. Because of the higher melting point of those fatty acids, they are generally found in solid state at reem temperature.
 
        
             
        
        
        
Answer:
The person’s urine will have a high specific gravity 
Explanation:
A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.
This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity
