Answer:
The spleen
Explanation:
The spleen acts as a filter for blood by recycling old and defective red blood cells. It also stores red blood cells, platelets and white blood cells.
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.
Air pressure (inside the lungs) is lowest when lung volume is highest, so the answer is B. when you breathe in your lungs expand, which makes the air molecules spread out, therefore the pressure is lower.
Answer:
the first one air pressure
