Some students used Vinegar to dissolve away the shells of three cous and use these con
models of human red blood cells. The students observed the changes in the eggs when they
were placed in different solutions
Red Blood Cell Model in Different Solutions
300 mL of
5 vinegar solution
300 mL of
pure water
300 mL of
corn syrup solution
Which statement best describes the role of the cell membrane in this model?

The cell membrane removes solute form the environment
The cell membrane allows water to enter and leave the cell.
The cell membrane allows solute the enter the cell, which causes the cell to shrink.
The cell membrane is an impermeable barrier that prevents water from entering the cell.
NO

click to let others know, how is it

where is the option.let me know

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus

its temperature is increasing. this causes molecular vibrations to increase.
