Answer:
what happens when the majority of the helium is the core has been converted to carbon
l.the rate of fushion will decrease
ll.the rate of fushion will increase
ll.the gravity will not squeeze the star
lV.the gravity will squeeze the star
choices:
A.l and ll
B.l and lV
C.ll and lll
D.ll and lV
Explanation:
When the majority of the helium in the core has been converted to carbon, then the rate of fusion decreases. Gravity again squeezes the star. In a low-mass star (with mass less than twice the Sun's mass), there is not enough mass for a carbon fusion to occur. ... The star becomes a multiple-shell red giant.
