Which of these does not contain a structural protein?
a. ligaments
b. ovalbumin
c. tendons
d. muscles
e. spider silk

The correct answer is option B. ovalbumin.

Explanation:

Ovalbumin is the protein that makes approx 55% of the egg white protein. It is a protein that shows homology to the serpin superfamily however it does not inhibit the process of serine protease.

The ovalbumin or OVA is not a structural protein but a storage protein that helps to provide nutrition to the embryo during embryonic development.

Thus, the correct answer is option B. ovalbumin

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
