Which of the following can be expected to occur as climate changes continues on earth? a] decreased melting of sea iceb] decreased migration of pets and pathogensc] increased freshwater sourcesd] increased coastal flooding

The correct answer is option D, that is, increased coastal flooding.  

The change in climate is enhancing the frequency of coastal flooding, comprising floods just from tides. The combination of melting of ice into the oceans and expansion of water as the ocean has warmed has increased the level of the sea up to about seven inches since 1900, and the elevation is on the rise.  

From 2005 to 2015, the average number of floods has doubled along the stretch of coast from Florida to North Carolina. The flooding will become even more usual in the coming time as the concentration of greenhouse gases discharged into the atmosphere will increase the levels of the sea in years to come.  

it should be all of them because it asks if you included all of those in your answer

explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
