Question

(02.01 mc) when property of water explains how water droplets are absorbed by a paper towel? waters adhesion to other types of molecules waters high specific heat waters high surface tension waters buffering capacity question 17 (02.05 mc) (multiple choice worth 4 points) all eukaryotic cells have a cytoskeleton, including plant cells, which have cell walls as well. what does the cytoskeleton in a plant cell do that the cell wall cannot? it acts as a framework inside the endoplasmic reticulum and keeps it from collapsing. it helps keep the organelles in place and directs their movement as needed.

Explanation:

First Question (Water Property):

To determine which water property explains water droplets being absorbed by a paper towel, we analyze each option:

• Water’s adhesion to other types of molecules: Adhesion is the attraction between water molecules and molecules of other substances. Paper towels are made of cellulose, and water adheres to the cellulose molecules, allowing the paper towel to absorb water.
• Water’s high specific heat: This property relates to the amount of heat energy required to change water’s temperature, which is not related to absorption by a paper towel.
• Water’s high surface tension: Surface tension is the cohesive force between water molecules at the surface, which allows insects to walk on water, not related to absorption by a paper towel.
• Water’s buffering capacity: Buffering capacity relates to water’s ability to resist changes in pH, which is unrelated to absorption by a paper towel.

So the correct property is water’s adhesion to other types of molecules.

We analyze the options for the function of the cytoskeleton in a plant cell (with a cell wall):

• "It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing": The cytoskeleton is a network in the cytoplasm, not specifically inside the endoplasmic reticulum.
• "It helps keep the organelles in place and directs their movement as needed": The cytoskeleton is responsible for maintaining the shape of the cell, organizing organelles, and facilitating their movement within the cell. Even in plant cells with a cell wall, the cytoskeleton performs these functions to ensure proper cellular organization and function.
• The other option (not fully visible but the selected one in the image seems to be incorrect based on the analysis, and the correct function is related to organelle positioning and movement).

Answer:

Water's adhesion to other types of molecules
