mote1985 [20]

Answer:

The correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.

Explanation:

The plant cell has a rigid cell wall that provides support to the plant cell that is not the case in the animals as they lack the cell wall. The low tidewater is an example of the hypotonic solution as it has fewer solutes than the plant cells or animal cells.

When a plant cell is in freshwater it takes up the water with the help of osmosis and begins to swell but the cell wall does not let it burst and become turgid.

Thus, the correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

  • x(t) is the value at time t.

  • x 0 is the initial value at time t = 0.

  • r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

  • t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
