Which of the following correctly describes quaternary level of structure in proteins?
A) It is when all the amino acids have joined together with
peptide bonds
B) It is when the hydrogen bonds have interacted with one
another to form shapes such as alpha-helices and beta- pleated sheets
C) It is when functional groups have been added to a protein
in the Golgi apparatus
D) It is when several folded proteins interact with one another
to form a protein complex
E) It is when side groups on the amino acids have interacted to
fold the protein into a specific three dimensional shape,

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.v

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

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.
