Answer: True
Explanation: The cell was placed in a hypotonic environment meaning that the concentration of water was higher outside the cell membrane than inside so water entered the cell.

Answer:
1.2The main processes involved in the movement of water between the different reservoirs are evaporation, condensation, transport, precipitation, runoff (water runoff from the ground surface), infiltration and transpiration
3.The large surface of the oceans (about 70 percent of the earth's surface is covered by oceans) favors the occurrence of large-scale evaporation. On a global scale, the same amount of water that is evaporated returns to Earth as precipitation. This however varies geographically
4.Earth from Space Although the engine of the cycle is the solar energy that originates the evaporation of liquid water, and therefore its passage into the atmosphere, the role of gravity is also fundamental, thanks to which precipitation falls and continental waters return to the oceans
5.The water cycle is powered by solar energy. The sun heats the surface of the ocean and other surface waters, which evaporates liquid water and sublimates ice, converting it directly from a solid to a gas. These sun-driven processes move water into the atmosphere in the form of water vapor

Answer:
C. CH4 + 202 – CO2 + 2H20
Explanation:
CH4+O2-CO2+H20
The above equation represents combustion of methane to produce carbon-dioxide and water.
One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.
The balanced chemical equation is:
CH4+202-CO2+2H2O
This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.
