Answer:
I thinks it's because since the water washed away all the land, the fish that was living in the water would be washed on land, and all the land animals might be either washed away along with the wave, or drowned due to not knowing how to swim or can't get out of the water in time when submerged underwater, causing almost all creatures living there to die out!
Wild guess but i want to say C
Sterile powdered agar with nutrients can be mixed with water, heated and then poured into empty petri plates or ready-to-use dishes can be purchased. The undigestible agar is a gelatin-like substance with a semi solid surface on which the bacteria can grow while they consume the added nutrients (like sheep's blood).
The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.
Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.
Due to this, water resists tendency to evaporate or to vaporize and therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.
