Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...
a.No, both bonds are highly polar.
b.Yes. O attracts electrons more strongly than C.
c.Right! O is electronegative, so O2 is polar.
d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.
e.No way. C is more electronegative than O.
Answer: d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.
Explanation:
Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.
Answer:
The process of cell division will slow down and the cell will die
Explanation:
Without the golgi apparatus or if its not working as well as it should be there would be no lysosomes or less. Without the lysosomes there will be a lot of junk/trash in the cell and it would have no way to break it down and get it out
The answer for this one is b) Looping of DNA
We knew hospitals as places where people get treatment. We
hardly imagine hospitals doing outreach to the community outreach nowadays.
Community outreach may improve patient outcomes, which is crucial for the
hospital to have access to payer’s reimbursements. One good example is giving outreach
to churches, since these institutions often have older and often sicker, individuals.
The hospital may directly engage with the church and give health education and
smooth transition from hospital to home. The hospital may also embrace social
media, or use Twitter to data-mine flu outbreaks in the community.
Explanation:
energy flows in only one direction through an ecosystem.
