Explanation:
Over its lifetime, a low mass star consumes its core hydrogen and converts it into helium. The core shrinks and heats up gradually and the star gradually becomes more luminous. Eventually nuclear fusion exhausts all the hydrogen in the star's core
Answer:
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Carbon number 1 is linked to the nitrogenous base (adenine, cytosine, guanine, or thymine).
Carbon number 3 is linked to the next nucleotide by a phosphate group.
Carbon number 5 is linked to the previous nucleotide by a phosphate group.
(The "next" or "previous" nucleotide depend on the direction your seeing it. I considered the 5'->3' direction.)
All the other carbons do not link to any other DNA component.
i cant really see the picture.
