<u>Answer:</u>
<em>The surface tension of any liquid is due to the attraction between the inter molecular forces. </em>
<u>Explanation:</u>
Strong inter molecular forces of attraction produces strong surface tension. If the hydrogen bond between the molecules gets disrupted then the surface tension also decreases.
When a liquid drops onto the floor then it assumes a spherical shape because the surface tension is minimum when the liquid assumes the spherical shape. Water has high surface tension and is important to environment.
Hi
Mutations are responsible for increasing the antibiotic resistance of some bacterial strains.
As we know that antibiotics are the drugs that target specific strain or type of bacteria, and kill them. These are designed against specific disease causing gene of that bacteria strain. However, as the genome of bacteria is very small in size, and bacteria undergo hundreds of multiplication events in very small span of time. Therefore, upon replicating, there occur chances of mutations in genetic sequence of bacteria.
When the genetic sequence of bacteria is changed even by one base, the drug wont be able to target and kill that strain of bacteria. And researchers need to design new antibiotic against new strains of bacteria.
Antibiotics resistance has become huge issue across the world as it takes alot of time (years) to design and approve an antibiotic.
Hope it help!
