Differentiation is the process by which a cell take on a specific function
and Morphogenesis is the process on which a organism take on a shape <span />
Yes, it is possible that evolution occurs in this case.
At first, the new insecticide is effective against the boll weevil. Spraying the insecticide will kill the boll weevil in a way. The insecticide might attack boll weevil enzyme or any part of its organs.<span>
But some of them might have a mutation that renders the insecticide ineffective. The mutation probably happens to DNA that code the enzyme or protein that targeted by the insecticide, makes the insecticide completely ineffective.
The next spray will kill all old organism, leaving the new resistant organism in less competition area. This will allow the resistant organism to grow fast and eventually replace all the old organism in the area.</span>
Phagocytes refer to the procedure by which some kind of living cells known as phagocytes engulfs or ingest other cells or particles. The phagocyte may be a free-living one-celled species, like an amoeba, or one of the body cells, like a white blood cell.
In higher species, phagocytosis is mainly a defensive mechanism against infection and invasion of the body by the antigens, that is, foreign particles.
Thus, phagocytosis is illustrated by most types of white blood cells ingesting bacteria, viruses, and other foreign substances.
A wild-type fruit fly exhibits the most common phenotype in the population.
Fruit flies of the wild type are yellow-brown in colour with brick-red eyes and longitudinal black rings across the abdomen.
An organism or strain displaying the wild type is one that has a phenotype, genotype, or gene that predominates in a natural population of organisms or strain of organisms as opposed to that of naturally occurring or laboratory mutant forms.
The genotype and phenotype standards of reference are wild type. Wild type is regarded as the norm and neither the dominant nor the recessive. In compared to the wild type, mutant alleles are either dominant or recessive.
Fruit flies are distinguished by their tiny size, brown bodies, and red eyes. While these pests themselves are not harmful, they may be a sign of unclean living conditions in the home.
