Answer:
Explanation:
Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.
While eating the chips, <u>the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution</u>. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. <u>This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis)</u> which causes dehydration in the individual and hence making the individual to be thirsty. <u>The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine </u>(because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).
Answer:
C
Explanation:
I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
ALOT of words please lmk if it makes sense
