Answer:

fusion

A star's energy comes from combining light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium were created in stars when lighter nuclei fuse to make heavier nuclei.

Plastids that are surrounded by more than two membranes are evidence of

dimaraw [331]

Answer:

d. secondary endosymbiosis.

Explanation:

When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.
