Bio You are riding a bike:
What will happen if you continue to bike and use energy, but do not have enough oxygen?
How can you stop what is happening?
How do athletes train in order to combat the process that is happening?

Down below

Explanation:

1. if you have a lack of oxygen while in a state of heavy movement your heart will stop pumping blood because your whole body isnt receiving enough oxygen and now everything will begin to shutdown

2. you cant stop anything unless you get oxygen , it will take longer for you to die with lack of oxygen or no oxygen at all for that matter

3. atheletes will usually take heavy breaths of oxygen before holding their breaths for longer periods of time

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

i'll try what topic lol
