What process can lead to an increase in the proportion of antibiotic-resistant bacteria?

This is due to mutation and natural selection. Only those who are resistant survive and therefore those carrying the genetic trait of being resistant will be the only ones breeding meaning this trait will be in the entire population.

This happens until a stronger antibiotic is used, where it will kill 99.9% of the bacteria allowing those to mutate into even stronger bacteria. This is the basis of a "super-bug" that will resist any known treatments.

What causes bacteria to increase?
They consume food, and divide themselves in a processes called cellular mitosis. It is the same process that lead to you building your body.
Which process performs genetic recombination?
Genetic Recombination is the exchange of genetic information in order to increase the genetic diversity of the population. Probably only with bacteria.
What is a definition for Urban Growth?
Urban growth is the rate of growth of an urban population. It is different to urbanization which is the process by which there is an increase in proportion of a population living in places classified as urban: the movement from a rural to urban area.
What The process called of measuring and marking stock to size and shape?
proportion
What is the process in which bacteria take up pieces of bacteria from their environment?
transformation
Does bacteria reproduce by growing and then splitting in two?
Binary fission
Which process in a multicellular organism is similar to the process of asexual reproduction in bacteria?
The process of mitosis.
By what process is nitrogen returned to the atmosphere by bacteria?
The process is called denitrification.
What is the process of reproduction called?
binary fission it is the process by which the bacteria divides
What does bacteria do in the process of conjugation?
Bacteria exchange genetic material during the process of conjugation to ensure the rise of another offspring which is genetically different.
How are bacteria effect human body?
Bacteria take over part of the internal mechanisms 'machinery' of the cell to produce more bacteria. In the process this disrupts the normal functioning of the cells and can even (or often) lead the death of the cells either as part of the life cycle of the bacteria or because vital functions of the cell are not being performed.
How can one slow the reproductive process of bacteria?
Bacterial reproduction can be slowed by increasing or decreasing the pH, providing them nutrient deficient medium. In process of reproduction, they also require phosphorus and iron. If there is an increase in pH they won't be able to assimilate iron and phosphorus.
