What is the question exactly
Answer:
The answer is B.
Explanation:
For just about everyone but especially for young and middle aged adults, because of their expected level of physical fitness, the single most important physical fitness component is "Cardiorespiratory Endurance" which is the term to measure how one's lungs, muscles and heart keep up together with intense exercise over a long period of time. Cardiorespiratory Endurance can be increased by correct nutrition and regular work-out sessions.
I hope this answer helps.
Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.
