Answer:
The correct answer is option d)"the percentage of pink flowers should increase over time".
Explanation:
In this study it is stated that two factors affect the flower coloration of <em>Claytonia virginica</em>: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.
 
        
             
        
        
        
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.
