You have two flasks (labeled A and B) that each contain an equal population of normal animal cells. You place flask A in a machine called a shaking incubator, which shakes the flask at 37°C and keeps the cells moving so as to not allow them to adhere to the bottom of the flask. Flask B is allowed to sit in an incubator (without shaking) at 37°C. If you let the cells in each flask grow for a week, which of the following results are you most likely to observe?1. The cells in both flasks A and B will have grown significantly.2. The cells in flask B will have grown significantly, but the cells in flask A will have not grown at all.3. The cells in flask A will have grown significantly, but the cells in flask B will have not grown at all.4. The cells in both flasks A and B will have not grown at all.

Explanation:

In these two flasks (labeled A and B) that each contain an equal population of normal animal cells.  The cells in flask A will have not grown at all, because  flask A is places  in a machine called a shaking incubator, which shakes the flask at 37°C and keeps the cells moving so as to not allow them to adhere to the bottom of it. The cells in flask B will have grown significantly, as Flask B is allowed to sit in an incubator (without shaking) at 37°C.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
