Explanation;
Gap junctions are tunnel like junctions that can occur anywhere along the lateral membranes of adjacent cells. They allow ions and small molecules to pass to one cell to the next for inter-cellular communication.
They function by allowing the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.The protein channels that make up gap junctions consist of two connexons. One connexon resides in the membrane of one cell.

Answer:
A)11,460 years
Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.
For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus
14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)
i.e it undergo two radioactive decay which means two half lives .
Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years
Answer:
D. New interpretations are a part of science.
hope this helps :)
