Answer:
Explanation:
The water cycle is the path that all water follows as it moves around our planet.
Answer:
It stores glucose that is taken from food so that respiration can happen later.
Answer:
When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
Explanation:
Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.
In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.
When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
Answer:
The Miller-Urey experiments essential to the theory of evolution because they showed how organic molecules could be made from Earth's early atmosphere.
