1. Polar covalent bonds are formed when the electrons in the
bond are not shared equally between the two nuclei. Which one of
these molecules through polar bonds? a. molecular oxygen b. methane
c. a hydrocarbon d. DNA
2. which motif is typically seen in cell membrane channel and
transport proteins? a. double helix b. alpha helix c. phospholipid
d. leucine zipper
Homework Answers
1. d. DNA
Oxygen, methane and hydrocarbon are non polar. But DNA is polar.
The back bone of DNA contains phosphate. It gives polarity to the molecule.
2. b. alpha helix.

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...

mestion Completion Status: Why did I suggest that the secret to life is electrons and protons? A. Because redox reactions are necessary for all of the reactions in live cells and these redox reactions require both H+ and electrons B. Because electrons carry a negative charge and protons have a positive charge C. Because most (not all) cells need electron transport and H+ gradients to make ATP D. Because electrons are necessary for the electrical responses of the cell (like...
