A: The runner's body will convert stored fat molecules into energy.

B: The runner's body will create the needed energy by breaking down proteins.

C: The runner's body will supply the needed energy by producing starch.

D: The runner's body will produce the energy by activating the Golgi apparatus.

Answer:

A: The runner's body will convert stored fat molecules into energy.

Explanation:

When the body needs energy to power cells, it uses ATP. ATP is generated by cellular respiration, which involves the breakdown of (usually) sugars by aerobic respiration.

If you exercise for a longer period such as during long distance running, your body will use more fat and less glucose in an attempt to conserve the limited glucose stores in case exercise intensity increases and oxygen availability is is reduced.

Which processes of the water cycle move water from the atmosphere into surface water reservoirs?
elixir [45]
A water reservoir is a natural or artificial lake in which water is stored for human use. The only process that can take water from the atmosphere (vapour) to a water reservoir is precipitation.

Precipitation is the process in which small water particles collide and join, making bigger water drops that will eventually be too heavy and fall to the ground in a process otherwise known as rain (if the water is in liquid state).


Answer:

\boxed{\bf~Precipitation.}


Hope it helped,
