Question 53 A wilted flower placed in a vase of fresh hwater for several hours became stiff and stood erect. When it was placed in a salt solution, it wilted. From this information, which of the following statements BEST describes the cells of the flower? O hypotonic to both freshwater and the salt solution O hypertonic to freshwater but hypotonic to the salt solution O hypertonic to both the freshwater and the salt solution O hypotonic to freshwater but hypertonic to the salt solution

The video clip mentioned a disaster scenario of a saltwater fish being placed in fresh water. What would occur if, instead, a freshwater fish was placed in saltwater? Your answer needs to have an arrow indicating the direction of water flow in osmosis, a label of "hypertonic," and a label for "hypotonic."

What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.
