Answer

Answer:

Question 1: the joining together of two or more smaller nuclei to form a larger one Question 2: Glycogen Question 3: Gamma decay Question 4: 12,000

Explanation:

Step1: Define nuclear fusion

Nuclear fusion is the combination of smaller nuclei to form a larger one.

Step2: Recall energy - storage polymers

Glycogen is a highly - branched polymer for short - term energy in animal cells.

Step3: Identify radiation type

Gamma decay releases high - energy/high - frequency electromagnetic radiation from the nucleus.

Step4: Calculate half - life time

If the half - life is 6000 years, to get to one - fourth (after 2 half - lives) of the original sample, $t = 2\times6000=12000$ years.
