Antibiotic-resistant bacteria are becoming an increasing problem. some bacteria that were once killed by common antibiotics have acquired the ability to survive in the presence of those antibiotics. how can bacteria acquire antibiotic resistance?

Bacteria evolve

Explanation:

Bacteria evolve and mutate to survive antibiotics as well as vaccines.

That is why there is no cure to the flu because doctors and scientists develop a vaccine and antibiotics for the past seasons flu.

These viruses and bacteria evolve to continue their life cycle. That is why certain bacteria are resistant to antibiotics and vaccines because they evolved, and mutated to the point where the man made cure against them does not work the same.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
