D is the best answer
(I am just using my common sense)
Hope I helped :)
<span>The answer would be: No, the baby is most likely in the REM sleep stage
</span>
One of the cycles of sleep called Rapid Eye Movement or REM. In this cycle, the eye is moving constantly and intermittently. The eye movement is not voluntary and the baby is not a sign of waking up. This cycle is important, so the parent should not interrupt it by waking the baby.
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.
Answer:
Hi! I think that it is D. I am not 100% sure on it though so I'm so sorry if thats
wrong. Hope this helps though!
Answer:
D. Useless
Explanation:
According to Dictionary.com, “in vain” is defined as “without real significance, value, or importance; baseless or worthless.”
