The word that describes the location of the gene for antenna length on chromosome #2 of the fruit fly is called locus. In the DNA of other fruit flies, the gene will be found at the exact same locus.
Antenna is the sensory organ present on the head of many insects. They are present in a pair. The antennae can be sensitive to touch, smell or any other senses. Due to their ability to sense or feel, they are also called feelers.
Locus is defined as the location or the physical place on the chromosome where a gene is present. The word locus is used to define the address of any particular gene. The loci are fixed for a gene in all the chromosomes of any organism.

Answer:
a. The cells are connected by gap junctions.
Explanation:
Gap junctions are the points of connection between the adjacent cells of animal tissues. These structures are formed by proteins which in turn form narrow channels in the plasma membranes of the neighboring cells. These channels allow the small molecules to pass from the cytoplasm of the one cell to that of another. The spread of dye to the neighboring animal cells would have occurred by gap junctions present between these cells.
