The action potential of contractile cells results in depolarization of the sarcolemma, which spreads down the t-tubules of an individual cell and spreads among cells via the (k) . Within a contractile cell, the action potential results in an influx of (l) ions into the intracellular fluid/sarcoplasm via the opening of the (m) .

Explain the cellular functions that occur when antibiotics attack a bacteria cell. a. antibiotics target the cell wall, cell membrane, and the processes of protein and nucleic acids production in bacteria to rupture the cell. b. antibiotics create dormant resistant endospores to preserve the genetic material and rupture the cell. c. antibiotics target the cell wall and form a bridge-like connection to form conjugation. d. antibiotics use binary fission to grow twice its size, replications its dna, and split into two cells.
