Muscle strength is the ability to exert a maximal amount of force for a short period of time. ... Think about lifting that heavy box when moving – that requires strength. Muscle endurance is the ability to do something over and over for an extended period of time without getting tired.

Answer:
B
Explanation:
Warm because land gains heat faster than water when heated by the sun. The heated land then transfers the heat to the atmosphere. The air mass is dry becasue a continent is mainly land and very little water (unlike oceans). There is, therefore, very little moisture in the continental tropical air mass. 
 
        
                    
             
        
        
        
Answer:
Differences in their boiling points 
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points. 
At different boiling points, each of the fraction will separate out. 
- Crude oil is made up of different fractions of hydrocarbons. 
- As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases. 
- Components with short carbon lengths rises out from the column first and are cooled and extracted. 
- The categories are thereby, classified based on differences in their boiling points.
