Indole is extracted from the medium and into the reagent layer (Kovac's) by the acidified butyl alcohol component and forms a complex with the p-dimethylaminobenzaldehyde, yielding the cherry red color seen when the culture is indole positive.
A pattern describes many observations but does not explain them. Patterns may be observed in data or phenomena, but the underlying cause or mechanism behind the pattern is not fully understood.
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.
One major weakness of Charles Darwin's theory during his lifetime was the lack of understanding of the mechanism of heredity. Darwin did not have access to the concept of genetics and could not explain how traits were passed down from one generation to the next. This gap in knowledge led to some skepticism and criticism of his theory of evolution by natural selection.
Charles Darwin's theory of evolution does not explain the origin of life itself, but rather how different species have evolved over time through natural selection. It also does not explain the mechanism of inheritance of traits, which was later elucidated by Gregor Mendel's work on genetics. Additionally, there are still gaps in our understanding of specific evolutionary pathways and processes, especially at more detailed levels.
Natural selection with modification of traits. He could explain natural selection, however he had no explanation for modification of the traits from generation to generation (this had to wait for Gregor Mendel's theory of genetics, and the later discovery of nucleic acids and Watson and Crick's study of DNA to explain the storage of genetic information chemically).
Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?
