That's science btw: there surve bye soaking in the sponge!!!
An organism that contains foreign DNA, which was inserted into its own genetic material, is called transgenic.
The only places with usable wter are lakes, rivers, and ponds
The methylene blue reduction test is a test commonly used to estimate the microbial load of a milk sample and as a result, examine the quality of the milk.
The principle of this test is that methylene blue is a dye which loses its colour in the absence of oxygen. Bacterial metabolism can cause the depletion of oxygen in the milk, therefore the methylene's reduction rate is connected to the presence of microorganisms in the milk.
As a consequence, if the tubes were not sealed tightly, then oxygen will enter the tube and the dye's colour will diminish, giving a false result concerning the presence of microorganisms in the sample.
<u>Answer:</u>
The process of "Osmosis" is modeled in the plant cell diagrams seen here.
<u>Explanation:</u>
Osmosis is the natural gross migration of solvent particles into a zone of higher solute concentration via a selectively permeable membrane, in the path that seeks to balance the amounts of solvents on both the ends. Osmosis as biological membranes are semipermeable, is a critical mechanism in biological systems.
Such membranes are usually impenetrable to massive and polar molecules like polysaccharides, ions and proteins while being porous to hydrophobic or non-polar molecules like lipids and to small molecules as carbon dioxide, oxygen, nitric oxides and nitrogen.
