The best and most correct answer among the choices provided by your question is the second choice or letter B "<span>The K + ion and the negative end of the water molecule."

</span>First you may remember a tip: 

<span>Like dissolves like. This means </span>

<span>polar solvents will get polar and ionic substances dissolved and </span>

<span>non-polar solvents will dissolve non-polar substances. </span>

<span>In KI Potassium K is +vely charged and Iodie I is _negatively charged. </span>

<span>In water H-O-H, Hydrogen is +vely charged and Oxygen is -negatively charged. </span>

<span>Polar ends of water attract opposite ions of KI (or any other ionic or polar substance) thus the ionic compound will dissociate and will be dissolved.</span>


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer is: D. The I⁻ ion and the positive end of a water molecule.

Dissociation of potassium iodide in water:

KI(aq) → K⁺(aq) + I⁻(aq).

Solvation is the interaction of solvent (water) with molecules or ions (in this example K⁺ and I⁻) in a solute.

Anion I⁻ has negative charge, so positive end (hydrogen atoms) of a water molecul attracts them.

Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute.

Answer:

How does non-human life in an urban ecosystem differ from that in an undeveloped forest ecosystem?

Explanation:

In forest eco system the people are uncivilized and not so much educated. And in urban eco system people are intelligent as well as educated this is the main reason. In an urban ecosystem, the only non-human life that live there are the ones that are able to survive under the conditions. However, in undeveloped forest ecosystems, there’s barely any pollution. Therefore, a bigger variety of non-human life is able to live here.
