Answer:
B. the fresh water is hypertonic and the salt solution is hypotonic to the cells of the celery stalks.
Explanation:
A hypertonic medium is precisely one that has a higher solute concentration than another medium. This, in turn, is hypotonic compared to the former. Thus, these classifications can only be employed in the sense of comparison and not as the primary definition of the osmotic characteristic of a solution.
When a cell is placed in a hypertonic solution, that cell tends to seek osmotic balance and absorbs some of the solution's solutes becoming rigid and hard. For this reason, we can say that fresh water is hypertonic in relation to celery stem cells.
On the other hand, when the solution is hypotonic, the cell trying to reach an osmotic equilibrium loses part of its solutes to the solution, becoming soft and flabby. For this reason, we can say that saline is hypotonic for celery stem cells.
Answer: C....Convection currents play a role in the movement of Earth’s inner core
The incorrect one in the Meiosis category would be,
"Same number of chromosomes as the original cell."
This is because the original cell would've had 46 chromosomes but the new cell only 23.
Answer: Keeping those genes locally in the mitochondria gives the cell a way to individually control mitochondria,” Johnston says, because pivotal proteins are created in the mitochondria themselves. ... Other structures in our cells could also benefit from this type of local control.
