Answer:
The correct answer would be c) food molecules.
A vacuole is a membrane-bound cell organelle present usually in the center of the plant cell.
It contains a high amount of water as it plays important role in maintaining the turgor pressure of the cell.
In addition, it contains a high amount of ions (such as K⁺, Mg²⁺, Ca²⁺), food molecules (such as glucose, sucrose, fructose), organic acids (such as malic, tartaric, quinic) and waste material.
Answer Options:
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.
Easy
how many times will it double
80/20=4
double 4 times
2*2*2*2=16
16 of them after 80 mins
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).
