An increase in human population negatively impacts the water resources. There is only a small amount of clean and drinkable water on Earth. If more people are on Earth, more of this water will be used by the population. An increase of people also means that more fossil fuel will be used.
<h3>How does human population impact water resources?</h3>
Population growth especially will limit the amount of water available per person, because an increase in per capita water consumption driven by development will intensify water demand, straining the local water supply.

The best answer is A
Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.
Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.
To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.

Answer:
Planaria.
Explanation:
The kingdom eukarys is divided into the different phyla including almost all the animals. The organism are classified on the basis of their level organisation, cavity and on the basis of coelom.
The cephalization is initial process for the deposition of nervous tissue in brain. The cephalization is absent in porifera and coelenterate. The planaria also known as flat worms shows the process of cephalization and this process becomes more complex in higher animals.
Thus, the correct answer is option (4).
