Oxygen is needed for the heart to oxygenate blood.
Physics is very common in our lives, and of course this also applies to the performance of a runner.
For example, he or she needs to understand the air resistance when running, they may need to find a way to reduce the most air resistance that is against them so that they can show their best performance.
Or another example is they may need to find out the friction acting on between their feet and the track, they may need to adjust their training in different textures of running tracks, as each acts a different amount of friction.
Answer:
lithosphere
Explanation:
Earth's lithosphere includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth. The lithosphere is subdivided into tectonic plates. Further there are two types of lithosphere mainly as oceanic and continental lithosphere.
Answer:
ICF to ECF
Explanation:
This is achieved by the evacuation of potassium ions (K+ ions) and sodium ions (Na+) from the inside of the neuron cells to the outside through ion channels. This process requires energy. This eventually leaves the inside of the cell electronegative relative to the outside (usually leaving an emf of -70mV).
