The answer is
<span>Aquifers are underground layers of rocks which contain water and serve as important sources of freshwater. They are located below the water table and in the saturated zone. If an aquifer becomes trapped between two impermeable layer (for example, one below and one above that overlies the aquifer), the pressure act on the aquifer and it can become a confined aquifer.</span>

<span>The answer is c, incomplete dominance. The dominate trait of the red petals is their red color. The dominate trait for the white petals is their white color. When their offspring have pink petals, neither parental phenotype trait is dominate over the other. Their colors are equally represented in the pink color of the offspring, which shows incomplete dominance - a case where neither parental phenotype is more visible than the other. The ratio of their colors represented in the offspring is one to one.</span>
ANSWER:
Problem faced include; habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, climate change etc.
EXPLANATION:
Problem:
Habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, and climate change are notable problems experienced by freshwater and marine fishes.
Solution:
Anthropogenic activities and stressors that rapidly threaten freshwater and marine fishes are curbed through legislation and other means to prevent extinction of fishes.
Through conservation programs that plans for individual species to more species of entire faunas of a particular location also boost population size and prevent hunting of threatened or endangered species in both realms.
Overtime, genetically modified fishes which can develop resistance to diseases are introduced to the realm.
Moreso, waste channels through which pollutants gets into the water bodies are well-treated for safety of fishes.
