The United States gets 81% of its total energy from oil, coal, and natural gas, all of which are fossil fuels. We depend on those fuels to heat our homes, run our vehicles, power industry and manufacturing, and provide us with electricity. Eventually, the degree to which we depend on fossil fuels will have to decline as the planet’s known supplies diminish, the difficulty and cost of tapping remaining reserves increase, and the effect of their continued use on our planet grows more critical. But shifting to new energy sources will take time. In the meantime, how do we use fossil fuels in the most efficient and environmentally responsible way possible?
If you must leave an injured or ill athlete unattended to get additional help, and you do not suspect an injury to the head, neck or back, then you should ask not to move while going for help, either by calling 911 or looking for someelse to help, once contacted help return immediately with the injured person and check that no threat has appeared to his life and provide care while the help gets there.

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!
