Answer: strong roots
Explanation:
Plants situated in fast-flowing area of a stream (aquatic environment) require certain body features to help them adapt to the fast blowing tides or waves of water, these include:
- a long slender stem
- strong roots for attachment and to withstand being uprooted by fast blowing tides 
- waxy leaves and stem with intracellular air spaces to maintain buoyancy and float above the water 
 
        
                    
             
        
        
        
Medical terminology is to create a standardised language for medical professionals. This language helps medical staff communicate more efficiently and makes documentation easier. This enables staff to save time by ensuring they don’t have to explain complex medical condition in plain English and can focus on the treatment of patients. Medical terminology can look and sound complex, but it's important to be able to break words down and understand their roots, prefixes and suffixes to prevent any misunderstandings or errors.
