"What would the world be like where water is as dense as a solid rather than a liquid?" Ideas occur.© BrainMass Inc. brainmass.com October 24, 2018, 6:36 pm ad1c9bdddf
Water, unlike other liquids, expands in its ice form, making it less dense than liquid water, thus allowing it to float when frozen. This property of water makes it ideal for supporting aquatic life. As water freezes, it ...
Water properties are explained.
Many of water's unique properties...
1. Many of water's unique properties are the result of its polar covalent bonds, which allow water molecules to form hydrogen bonds with each other. What if water molecules instead had nonpolar covalent bonds? Make a list of hypothesis about the ways in which this change might affect the properites of water. Describe how each change would effect living things. Design an experiment to test one of your hypothesis.
2. Plant roots take up minerals (inorganic ions such as potassium) that are dissolved in the water of the soil. The concentration of such ions is usually much lower in the soil water than in cytoplasm of root cells. Design the plasma membrane of a hypothetical mineral-absorbing cell, with special reference to mineral-permeable channel proteins and mineral-transporting active-transport proteins. Justify you choice of channel proteins and active-transport proteins.View Full Posting Details
