Hey There!
cardiorespiratory endurance is how long you can do a activity without taking a break.

Dear Chairman,
I have some ideas on helping students achieve higher results. First idea I propose is making a study time where students can study in their most comfortable way possible. This promotes more learning and will make the process much faster as students will be doing it in a way that suits them. Another idea is to give lessons on how to be more productive at home and balancing everything to make time for self care and studying.
Sincerely, (your name)
You didn't provide a graph? Generally, when we're talking about homeostatis, we're talking about the neutral state of the body during which it can function optimally. If you've provided a graph which involves the human body under an intense workload, then we can be sure that during this period the body isn't under homeostasis.
