No, the chemical equations for both processes are evidence that matter and energy or neither created nor destroyed
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!

Homeostasis:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
The lateral malleolus found on the distal lateral surface of the fibula is responsible for the bony bulge on the lower leg.
The lateral malleolus is the prominence on the outer or lateral side of the ankle. It is pyramidal in form and somewhat flattened. In clinical significance, a bimalleolar fracture is an ankle fracture that involves both the medial and lateral malleolus. This condition is more common in women especially the 60 year old age group. Another clinical condition of the said anatomical structure is the trimalleolar fracture which involves the lateral, medial, and the distal posterior aspect of the tibia or the posterior malleolus. This is primarily caused by ligament damage and dislocation.
Answer:
Bacteriophage
Explanation:
Bacteriophage is nothing but a virus that harms and kills the bacteria.
The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.
It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.
They used sulfur-35 and phosphorus-32 radioactive isotopes to trace the DNA and the proteins.
