Answer:
The correct answer is - solubility
Explanation:
Solubility is the nature of the material that is a chemical property of that specific solute ability to dissolved in a solvent. The ability of solute or material in a solvent or liquid is measured by the term of the maximum amount of that material dissolved in the liquid at equilibrium.
Sugar and water is a great example of solubility. When sugar is missed in the water it dissolved in water and disappear in the water here sugar is solute and water is solvent.
Thus, the correct answer is - solubility.
Divergent evolution is when two different species share the same ancestral origins but have evolved differently whereas convergent evolution is when species with different ancestral origins have developed similar features.
In convergent evolution, two species that are not necessarily closely related develop similar features often as a result of adaptation to similar conditions.
To bring oxygen in the body because it is a respiratory organ fish
Answer: Chromosome
The polynucleotide DNA strands are wrapped on circular proteins called histones which then are condensed into a structure called chromosome.
Hi there!
<u>Electronegativity</u> is the concept of how likely an atom is to attract the shared molecules in one of these bonds to itself. We know the molecule water is made up of two hydrogens and one oxygen. The electronegativity of hydrogen is 2.2, and oxygen 3.4. An <u>ionic bond</u> needs at least a difference in electronegativity of 1.6. As the difference is less than that, we can say that water is a covalent molecule. This then wipes out choice B, because it is not ionic, and C, as we have seen it is actually covalent.
Now, we can see the difference in electronegativity between oxygen and hydrogen is still 1.2. This means that while it is not at the point for there to be an ionic bond, there is still a difference in attraction, where the electrons will tend to favor the oxygen more and 'hang around it' more. As electrons are <u>negatively charged</u><em><u>,</u></em> this means that the oxygen will gain a slightly negative charge. This then makes the molecule polar, because it now has a charge within the molecule. This means we have our answer, choice D.
In terms of hydrophobic molecules - they tend to be ones without a charge. (If you're interested in this kind of stuff, I'd search hydrophobic up, and possibly also look into hydrogen bonds).
Hope this helps! Feel free to ask me any other questions you have about this specific problem.
