Answer:
The answer to your question is: after two hours there will be 6400 cell/ ml
Explanation:
Data
Bacteria t = 0; 400 cells/ml
generation time = 30 minutes
# cells after two hours = ?
                                  # of bacteria               time
                                      400                            0
                                       800                         30 min
                                    1600                           60 min
                                    3200                           90 min
                                    6400                          120 min
 
        
             
        
        
        
The answer is that a unicellular organism would swell and burst.
In a hypotonic solution <span>the </span>water concentration<span> of the cell's cytoplasm is </span>lower<span> then that of the hypotonic solution. If unicellular organism is exposed to a hypotonic solution, the water from the solution will enter the organism by the process called osmosis. The aim is to balance water concentration on the inside and outside of the organism. But, that water entering the cytoplasm of the cell will make pressure on the cell membrane. If the </span><span>excess water cannot be removed from the organism, it will swell and burst.</span>
        
                    
             
        
        
        
The plant cells communicate across cell walls through Plasmodesmata.
how do plant cells communicate across cell walls?
- Between tiny channels woven through the walls of neighboring plant cells, plant cells can communicate with one another through channels referred to as plasmodesmata. 
 - These channels enable chemicals to move freely between cells, allowing plants to grow regularly and form tissues and organs.
 - However, plasmodesmata also act as entryways that viruses can employ to infect an increasing number of cells. 
 - Given these advantages and disadvantages, plants must balance the permeability of their plasmodesmata in order to move materials from one cell to another while preventing the spread of infection.

Primary succession can occur in essentially lifeless areas or regions in which the soil is incapable of sustaining life as a result of such factors as lava, sand dunes, or rocks left from a retreating glacier.
