a red onion cell has undergone a change, as represented in the diagram below. This change is most likely due to the cell being placed in...
Answers
We can see that the cell is shrivelled meaning osmosis has taken place. So it must be salt water
A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.
What is osmosis?The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.
Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.
What are the types of osmosis?An isotonic solution contains the same solute concentration both within and outside the cell.A hypertonic solution has a larger solute concentration outside than inside the cell.A hypotonic solution contains a larger concentration of solutes inside the cell than outside.Thus, we can conclude that when a red onion cell is placed in salt water.
As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.
So, option (3) salt water is correct.

Monosomy: the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
A trisomy is a chromosomal disorder characterized by an additional chromosome, so the person has 47 instead of 46.
Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).
So, the correct answer is 'Monosomy'.
