Answer:
Having bacteria would produce organic molecules and defeat the whole purpose of the experiment which is to make organic molecules from inorganic molecules. The experiment was supposed to demonstrate the formation of the first organic molecules that initiated life on primordial earth. It is believed that lightning powered the formation of the first simple amino acids, like glycine, from the primordial atmosphere which was mainly composed of carbon dioxide and methane.
Osmosis is the diffusion of water across a semi-permeable (or differentially permeable or selectively permeable) membrane. The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.

They have the same molecular formula but different structural formulas

Answer:
Net Primary productivity
Explanation:
In an ecosystem, primary productivity is a term used for autotrophic organisms. It is the process by which these organisms like plants, green algae etc. make their own food using inorganic sources. However, they do not utilize all the matter they make from this process.
The NET PRIMARY PRODUCTIVITY (NPP) is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration. This means that NPP is the amount available after removal of the one to be lost via respiration i.e. NPP = GPP - respiration.
