Phagocytosis would enable a white blood cell to ingest a bacterium

Phagocytosis is a special form of endocytosis by which cells ingest solid substances including microbial pathogens to produce an internal compartment known as a phagosome. Cells that undergo this process are called phagocytes. The white bold cells of the immune system protect the body against invasion by pathogens such as bacteria. They perform this function by phagocytosis.

An effective strategy for stepping in if someone appears to need help is directly check in with the person.

But we shall realize the fact that many people will not ask for help themselves due to certain reasons.

So, it is best to always check upon the persons you love if you think that they might need any help.

Does this mechanism produce a change in individuals or populations? Explain

I am Lyosha [343]

<h2>Answer:</h2>

mechanism: the process of evoluton .

Evolution is the process by which veriety of modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all 0rganisms and the amazing diversity of that organisms but exactly how does it work? Fundamental of the process of evolution is genetic variation upon which selective forces can act in order for evolution to occur.

Examines the mechanisms of evolution focusing on:

•Decent : the genetic differences that are heritable and passed on to the next generation successfully.

• mechanisms of change: Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .

• The random nature of genetic drift and their effects .

• How variation, differential reproduction, and heredity result in evolution natural selection .

• How different species can affect each other's evolution through co-evolution.

All of these mechanisms can cause changes in the frequencies of genes produce change in in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.
