Mass, what its made out of, and atomic number
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a <span>large dipole moment. However, because one dipole points to the left and the other to the right the dipole is cancelled.</span>
Answer:
Modern whales evolved by natural selection over long time periods through descent from common ancestors
Explanation:
According to the evolutionary theory proposed by Darwin, natural selection is a biological process by which organisms adapt and change in response to their environment. In this case, ancient whales that were better suited to environmental conditions survived and produced more offspring than non-adapted individuals. In consequence, predominant adaptive traits observed in modern whales were favored by natural selection in the past, while unsuccessful phenotypes progressively disappeared.
Electrolytes are those which dissociates in solution and produces ions.
Ions can carry current,so Electrolytes conduct electiricity.
And non electrolytes are those which do not dissociate in solution and doesnt produce ions.
Since non electrolytes do not produce ions they cannot conduct electricity.
<u>Hence the right option is:</u>
B) Non-electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
