Answer: 3
Explanation:
The black widow, the hobo spider, and the brown recluse spider are all poisonous. They all have lethal venom.
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.
Onion is an underground crop and it have no involvement in the photosynthesis. So it have no chloroplast in their cell.

Answer:
Ein Magnetfeld kann erzeugt werden, indem Elektrizität durch einen Draht geleitet wird. Alle Magnetfelder werden durch Bewegung geladener Teilchen erzeugt. Sogar der Magnet an Ihrem Kühlschrank ist magnetisch, weil er Elektronen enthält, die sich ständig im Inneren bewegen.
