Methane gas is more potent( roughly by 30 times), as a greenhouse gas than carbon dioxide.
Explanation:
Greenhouse gases in the atmosphere trap infrared radiation (responsible for the transfer of heat) that reflects off of the earth's surface instead of allowing most of this radiation to escape to space. This causes heat to build up in the atmosphere. The more the greenhouse molecules are in the atmosphere the higher this effect is. Global warming is subsequently blamed for climate change around the world.

The answer to which of the following is extrusive is letter B. lava
Answer:
Answered below
Explanation:
Pepetidoglycans are the structural polymers which make up the cell walls of most bacteria.
It consists of the macromolecule, glycan chains, which are repeating N-acetylmuramic acid and N-acetylglucosamine residues. These glycan chains combine or cross-link with peptide side chains (proteins) to form a mesh-like layer outside the plasma membrane of most bacteria.
Peptidoglycan is the major structural component and the basic unit of the bacterial cell wall and provides protection to the cytoplasmic membrane, mechanical rigidity and also regulates the passage of fluid, amino acids, sugar and ions, in and out of the cell.
