I'm guessing here but, some advantages are, embryonic stem cells are very effective at repairing damaged tissues, but they are difficult to obtain, and either have to be obtained from umbillical chords of babies, or from fertilized embryos from a laboratory. So I am guessing they would be expensive/difficult to source because you would either have to collect umbillical chords from babies, or have to purchase eggs from women, and they are ethically questionable to use because you are essentially making potentially viable embryos and then killing them. Hope this helps.

A swamp is a wetland that is forested. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Many swamps occur along large rivers where they are critically dependent upon natural water level fluctuations. Other swamps occur on the shores of large lakes.
Answer;
Natural selection
Explanation;
-Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.Genetic diversity allows the different organisms to have different physiological characteristics. Some of them provides them with genetic resistance, others don’t. The ones which are resistant survive the pesticide, others don’t ; this is known as natural selection.
-Those that are resistant will live longer and have a larger number of offspring (reproductive success). From one generation to another, there will be more and more resistant pests (because of their larger offspring), and less and less pests that are not resistant (because they tend to die young). If the selection process goes on, someday the pesticide will be useless (it will kill no pest).
