Why is the polarity of water molecules and hydrogen bonding essential to adhesion and cohesion?
Some properties like Polarity makes water a good solvent, cohesion helps in stick water molecule to itself while adhesion helps it to stick with other surfaces. Water have surface tension due to hydrogen bonding.
What are the difference between adhesion and cohesion ?when two similar molecule come closer adhesion occur where as in cohesion two similar molecules face the force of attraction.
Adhesion is the force of attraction observed between the water molecules and xylem vessels while Cohesion is unrestrained among water molecules.
Capillary action and meniscus are the effects of adhesion while Surface tension, meniscus and capillary action are the effects of cohesion.
The major forces responsible for adhesion are electrostatic or mechanical forces while Cohesion is the result of hydrogen bonding and Van der Waals forces.
A strong adhesion can lead to spread of liquid all over the surface while cohesion forms water droplets.

what is the function in a cell of the carbon compounds lipids
Answer:
Lipids are organic compounds that consist of carbon, hydrogen, and oxygen. They are made up of fatty acids and other compounds. They provide cells with energy, store energy, and help form cell membranes.
Carbon, hydrogen, and oxygen are the main components of lipids, which are organic molecules. Fatty acids and other substances make them up. They aid in the formation of cell membranes, supply energy to cells, and store energy.
What is function of carbon compounds lipids in cells?In a cell, lipids carry out a variety of tasks. Cells store energy as lipids termed fats for long-term use. Lipids also insulate plants and animals from their surroundings.
All cells are fundamentally made up of lipids, which also serve a variety of crucial functions.
They are essential parts of the nuclear membrane, endoplasmic reticulum, Golgi apparatus, and trafficking vesicles like endospores and lysosomes.
As well as other cellular compartments, including the plasma membrane.
Therefore, lipids have various the function in a cell as a carbon compounds.
