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.
Answer:
The plasma membrane is a phospholipid
Explanation:
The plasma membrane is phospholipid bilayer. The layers are two and are continuous flat sheets. They have proteins and cholesterol embedded in them, for facilitating the transport of compounds and maintanng fluidity. The lipid bilayer is both hydrophobic and hydrophillic.
Answer: Second option is correct.
Explanation:
Valley and mountain breezes are examples of local winds.
It occurs one by one on a regular cycle.
Valley and mountain breezes is similar to sea and land breezes.
Hence, second option is correct.
A.
Activation energy is the energy needed for a reaction
