1. I’m not really sure how to answer it, i think it’s parasitic 
2. The tick is the parasite since the human is the host 
3. It’s symbiosis bc it’s a long term biological interaction between two different biological organisms (the human and the tick) and in this case it’s parasitic bc one benefits off the host but it’s harmful towards the host so it doesn’t benefit each member.
Hope that helps :)
        
             
        
        
        
Answer:
The greatest changes to the path and strength of the Gulf Stream might be caused by an increase in the volume of river water that flows into the Gulf of Mexico (Option B)
Explanation:
The North Atlantic current or Gulf Stream carries warm water from the Gulf of Mexico forward Europe, providing a relative template clime in most of the European occident. 
Ocean streams are sensitive to the amount of freshwater available on the surface. An increase in overflow and precipitation over the ocean could slow or revert the north Atlantic current, blocking warm water flow to Europe.
 The deposition of freshwater could cause a temporal deceleration or total collapse of the North Atlantic Current, and this interruption might lead to very cold periods in the North Atlantic.
