The answer for this question would be Integument, digestive, respiratory and urogenital.
The largest system that contact with the external environment would be integument and digestive. That makes two system has normal flora of microbes and not sterile like the other systems. Normal flora of microbes will prevent the pathogen microbe grows so it gives some benefit.

<h3>How the bacterial growth curve relates to what happens to the bacterial population?</h3>

The bacterial growth curve symbolizes the number of live cells in a bacterial population over a period of time. There are four different phases of the growth curve: lag, exponential (log), stationary, and death. The initial phase is the lag phase where bacteria are metabolically functional but not dividing.

<h3>What are 4 states of bacterial growth?</h3>

Bacteria can live in more burning and colder temperatures than humans, but they do best in a warm, moist, protein-rich atmosphere that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria flourish in extreme heat or cold, while others can stay under highly acidic or extremely salty conditions.

The drug cytochalasin B blocks the function of actin. Which of the following aspects of the cell cycle would be most disrupted b

Sladkaya [172]

The correct answer is: E) cleavage furrow formation and cytokinesis

Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
