The life cycle of most microorganisms is fast, so in a matter of days you might go through multiple generations, in each generation the useful mutation selects more survivors.
This does not work for microorganisms which grow very slowly. Some organisms deep underground are believed to live for hundreds of years.
In a wet mount, microorganisms move more freely and quickly due to the open environment. In a hanging-drop mount, microorganisms tend to move slower as they are trapped in the drop of liquid suspended from the coverslip, restricting their movement.
Evolution can occur slowly over long periods of time, as changes accumulate in a population's genetic makeup. However, some evolutionary changes can also happen relatively quickly in response to environmental pressures or other factors, such as in the case of adaptive radiation or rapid genetic mutations.
When an organism reproduces quickly, the population increases rapidly. This can lead to competition for resources like food and space, potentially causing overcrowding. In the long term, it can result in environmental degradation and increased vulnerability to disease or predation.
In terms of evolution, bacteria are some of the fastest evolving organisms on Earth. This is because they reproduce so quickly (sometimes in 20 minutes) and that means that more organisms are made and more variation exists. This allows for more traits to be selected by natural selection, resulting in the fastest trait changes within a population.
Mutations are not always bad, there are certain cases where a second mutation overcomes the effects caused by the initial mutation. Mutation may enable the mutant organism to withstand particular environmental stresses better than wild-type organisms, or reproduce more quickly. In these cases a mutation will tend to become more common in a population through natural selection. Carriers of the sickle cell allele are resistant to malaria, because the parasites that cause this disease are killed inside sickle-shaped blood cells. So, this suggests that mutations are not always bad, they are also beneficial some times.
Yes, organisms can evolve rapidly through processes such as natural selection, genetic mutations, and gene flow. Environmental pressures and changes can drive populations to adapt and evolve quickly in order to survive and reproduce effectively.
on bacteria it will stop them from growing too quickly
Cancer. When cells divide in an unregulated fashion, mutations occur. These mutations quickly become a larger problem in the body, forming cancer tissue.
Without microorganisms, we would die very quickly. For every 1 "human" cell in your body, there are about 10 "other" microorganisms in and on your body. Every aspect of life revolves around microorganisms, such as bacteria and fungi, essential to every aspect of life. Without microorganisms, everything would cease to exist.

Deleterious mutations can be quickly eliminated in haploids because there is no masking effect from a second copy of the gene. In diploids, the presence of a functional copy of the gene on the other chromosome can compensate for the deleterious mutation, allowing it to persist in the population. In haploids, the deleterious effects are more pronounced because there is only one copy of the gene, leading to faster elimination through natural selection.
population density
A mutation would have the most impact on allele frequency in option A, where the population is large. In a large population, mutations can introduce new alleles, and if these alleles confer a selective advantage, they can spread quickly due to the reduced effects of genetic drift. In contrast, options B and C involve movement and gene flow, which can dilute the effects of mutations by mixing alleles from different populations. Option D is incomplete, but generally, smaller populations would have a more pronounced effect from genetic drift than large ones.

Population demonstrating a life history pattern in which members grow quickly. The members are small in size, mature quickly, and dont require much adult supervision. They produce quickly and have a short life span.
To quickly see which country has the most people, you should use a population distribution map.
