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!
Answer:
The resources will be mostly taken up by the invasive birb species
Explanation:
The resources cannot be evenly divided between the species as the harmony has been interrupted
Nuclear power is a clean and efficient way of boiling water to make steam, which turns turbines to produce electricity. Nuclear power plants use low-enriched uranium fuel to produce electricity through a process called fission—the splitting of uranium atoms in a nuclear reactor.

Explanation:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.
Answer:
C
Explanation:
Genes, choromosomes, and the nucleus (contains the DNA) are all apart of genetics.
