Answer:
1. 2. 4. 5. 7 and 8
Explanation:
3. False: A single stimulus can activate multiple target cells.
6. False: A ligand does not phosphorylate protein residues but can bind and activate kinase receptors resulting in conformational changes that induce intracellular phosphorylation of target protein domains.
9. False: Second messengers relay stimulus to intracellular targets. e.g calcium can act as a second messenger.

Answer: STABILITY OF THE DNA MOLECULE.
MOLECULAR STRUCTURE OF DNA.
EASY SEPARATION OF DNA
HIGH BOILING POINT OF WATER
COHESIVE FORCE HOLDING WATER MOLECULE TOGETHER
Explanation: Although Hydrogen bonds are weak,they help in stabilising the DNA.
Hydrogen Bonds are weak bonds which connects the Nitrogen bases together in a DNA,which gives the structure of the DNA.
They also aids the Easy separation of a DNA molecule.
The Hydrogen bonds are the main factor that ensures that the boiling temperature of water is high.
Hydrogen bonds are cohesive in nature, they bind water molecules together through and cause it to resist heat and high temperature.
