Serggg [28]

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.

Define los tipos de proteínas que conforman la membrana
tensa zangetsu [6.8K]

Membrane proteins can be classified into two broad categories—integral (intrinsic) and peripheral (extrinsic)—based on the nature of the membrane-protein interactions (see Figure 3-32). Most biomembranes contain both types of membrane proteins.

Translate:

Las proteínas de membrana se pueden clasificar en dos categorías amplias: integrales (intrínsecas) y periféricas (extrínsecas), según la naturaleza de las interacciones membrana-proteína (véase la figura 3-32). La mayoría de las biomembranas contienen ambos tipos de proteínas de membrana.

a sample of dna contains 20 percent adenine and 30 percent cytosine. What percentage of tymine would you expect to find.
romanna [79]
20 percent.

Since one strand is 20, the opposite that would connect with it (Thymine) would have the same amount so the total would be 100.

Hope this helps!
