Answer:
Gap junctions within the intercalated disks
Explanation: Gap junctions within the intercalated disks allow impulses to be propagated from one cardiac muscle cell to another. It allows sodium, potassium, and calcium ions to flow between adjacent cells, propagating the action potential, and ensuring coordinated contractions.
Answer:
Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... The contractile ring shrinks at the equator of the cell, pinching the plasma membrane inward, and forming what is called a cleavage furrow.

Answer:
The correct answer will be option- C.
Explanation:
The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.
These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.
Thus, option- C is the correct answer.
In a ring species gene flow occurs between neighboring populations of a species, but at the end of the ring populations don’t interbreed.
