O-H bond is referred to as the most polar.
Explanation:
O-H bond is said to be most polar because the electronegativity is different. Electronegativity can be said as the atom's ability to attract electrons towards itself. Electronegativity of an atom increases when there is a movement on the periodic table from left to right.
When the electronegativity between the atoms are different then it is said to be a polar bond on the other case if the electronegativity between the atoms are same it is said to be non- polar bonds.
Codominance is the answer good luck u got a good grade
A mixture
If the elements or compounds aren't chemically bonded then they are known as a mixture :)
The following statements are true about the modification of chromatin structures in the eukaryotes:
1. Melthylation of histone tails in chromatin can promote condensation of the chromatin.
2. DNA is not transcribed when chromatin is package tightly in a condensed form.
3. Acetylation of histone tails in chromatin allows access to DNA for transcription.
4. Some form of chromatin modifications can be passed on to future generation of cells.
5. Acetylation of histone tails is a reversible process.
