As the sun ages, it contains: A. more oxygen and less helium.
B. more hydrogen and less helium.
C. more helium and less hydrogen.
O D. more carbon and less nitrogen.

The correct answer is C. More helium and less hydrogen

Explanation:

The Sun, which is the center of the solar system, is mainly composed of two gases: hydrogen and helium. Additionally, every second and through nuclear fusion the hydrogen is fused and this creates helium, which is a heavier element. This implies as the sun ages the amount of hydrogen will decrease as the amount of helium increases, as a result of constant nuclear fusion. Indeed, right now helium exists in a lower quantity than hydrogen, but every second, minute, hour, etc. the amount of helium increases, and it is expected in millions of years there is more helium than hydrogen.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
