Which person is likely to have the fastest metabolism? and which is the likely to have the slowest?
a) 15 year old boy
b) 15 year old girl
c) 65 year old man
d) 65 year old woman

The 15 year old boy has the fastest metabolism, while the 65 year old woman has the slowest metabolism.

Explanation:

Metabolism is faster in younger people. As we age, this metabolism gradually "slows down". The "slowing down" of metabolism occurs by some combined factors. There is a natural process of hormonal changes, including a decrease in the production of GH and testosterone. With the drop in the level of these substances, the body tends to lose muscle mass - a process known as sarcopenia -. Muscles are totally linked to our energy consumption, as the body spends a lot of energy to maintain them. For this reason, we can conclude that 15 year olds have a much faster metabolism than 65 year olds.

In addition, men's metabolism tends to be faster than women's metabolism. In women, metabolism is slower because they have more fat mass. Routine physical exercise is a solution to speed up metabolism, but men will always have the advantage (considering a healthy man).

is there any answer choices to this?

minerals contribute to our overall health because they your body grow, develop, and stay healthy. our bodies use minerals to us function throughout the day.tromhey us build strong bones, so we can do more things in life. with certain minerals, they can you maintain a normal heartbeat!

though, as as minerals are for us, they can also be very dangerous if one were to consume too many. if you were to take too much minerals, or even vitamins, you could experience nausea and diarrhea. all trace minerals can be very toxxic at high levels of consumption. taking too much of some minerals will result in hair loss! but this goes with almost everything in life, taking too much of something that is good, will eventually be bad for you.

my intake in minerals was normal. there really is no need to improve, i am healthy, and i am experiencing no nausea or diarrhea. i am as healthy as a bee. ☺ (sorry that i cannot you with the mineral intake)

what i have learned so far is that taking too much something can be very bad for you. taking too many minerals or vitamins, or anything healthy in general, can result in nausea and diarrhea, as well as hair loss. it would be a good idea to track what you put into your body, good or bad.
