What happens when a bacterial cell is placed in a solution containing 5 percent NaCl?
When placed in a 5% NaCl solution, a bacterial cell will likely experience water loss through osmosis due to the high salt concentration outside the cell. This will cause the cell to shrink and may lead to dehydration and cell death if the salt concentration is too high.
What happens to molecules with sufficient energy when a liquid is placed in a closed container?
When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
What happens to Ionic solids when placed in water?
When placed in water, ionic solids will dissolve as the water molecules surround and separate the ions from the solid lattice. This results in the ions dispersing throughout the water, forming an aqueous solution.
What happens to water when placed in a vacuum?
When placed in a vacuum, water will start to evaporate due to the reduced air pressure. As the pressure decreases, the water molecules gain enough energy to break free from the liquid and turn into water vapor.
What happens when iron is placed in copper sulfate solution?
When iron is placed in copper sulfate solution, a chemical reaction occurs where the iron displaces the copper in the solution, forming iron sulfate and copper metal. This is known as a displacement reaction.
What happens when a bacterial cell is placed in a solution containing 5 percent NaCl?
When placed in a 5% NaCl solution, a bacterial cell will likely experience water loss through osmosis due to the high salt concentration outside the cell. This will cause the cell to shrink and may lead to dehydration and cell death if the salt concentration is too high.
Why is penicillin placed in the group ascomycetes though sexual reproduction is absent in them?
Because penicillin is made out of the fungus ascomycetes.
What will happen if a gram-positive bacteria is placed in distilled water and penicillin?
no changes
What happens if a bacterial cell is placed in water by osmosis?
If a bacterial cell is placed in water by osmosis, water will move into the cell due to a lower concentration of solutes inside compared to the outside environment. This influx of water can cause the cell to swell and potentially burst if the cell wall is not strong enough to withstand the pressure, a process known as osmotic lysis.
What would happen if a suspension of bacteria is placed in a distilled water with penicillin?
eventually the bacteria would die because the penicillin would interfere with the ability to synthesize a cell wall thus the bacteria wouldn't divide. and the existing bacterial cell wall would lengthen and become frail. However, the bacteria must be gram-positive because they have cell walls composed of peptidoglycan, which is ideal for penicillin to attack.
What happens when pollen grains are placed in a 10 percent sugar solution?
When pollen grains are placed in a 10 percent sugar solution, they will absorb water from the solution through osmosis. This can cause the pollen grains to swell and become turgid. The sugar solution provides a hypertonic environment, leading to an influx of water into the pollen grains.
What percent of garbage is placed into landfills?
21%
Which term describes what happens to a cold balloon when placed in hot car?
which term describes what happens to a cold balloon when placed in a hot car
What happens to denim when it is placed in a flame?
burns
What will happen to freshwater bacterial cell that is placed in salt water?
Water leaves the cell, causing the cell to shrink.
What will happen to a freshwater bacterial cell that is placed in salt water Will water enter or leave the cell?
If a freshwater bacterial cell is placed in salt water, water will leave the cell due to the higher concentration of solutes in the surrounding salt water. This process is known as plasmolysis, and it can lead to the bacterial cell shriveling up and potentially dying due to dehydration.
What happens when bacterial cell is placed in 5 NACL?
5% NaCl solution is unusually high. And because all living organisms seek to maintain an isotonic balance with their environment,osmotic diffusion will occur in order to re-establish this balance.Hence,there will be a diffusion down the gradient i.e. from the medium containing the NaCl solution,into the bacterial cell which has solutes dissolved in it but insufficient to even out this balance.The end result will then be lysis or bursting of the bacterial cell,as it gorges in the NaCl to maintain equilibrium.
