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...
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.

List reasons you would or would not be concerned about eating genetically modified food
Answer:
Reasons I would be concerned about eating GMO foods:
Explanation:
The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.
Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.
The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.
Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.
Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.
