Answer:

Chitin is a fibrous material made up of polysaccharides that is found in the exoskeletons of arthropods and the cell walls of fungus. Chitin is an important biopolymer found in nature. Fungi, arthropods, and nematodes are the principal producers. In insects, it acts as a scaffold, supporting the epidermis and trachea cuticles, as well as the peritrophic matrices that line the gut epithelium.

Is mitosis involved with two sets of nuclear divisions
Naya [18.7K]

Answer:

NO. Mitosis involves one set of nuclear division and results in two nuclei that are exactly the same as the original. On the other hand, meiosis involves two sets of nuclear divisions.

Explanation:

Mitosis is a type of cell division normally occurring at the sites of growth and development of new tissues and also at sites of repair. It also occurs during asexual reproduction of organisms. Each mitotic cell division is a process that follows distinct phases.

Each mitotic division results in the formation of two daughter cells which are genetically identical to the parent cell, that is they have the same number and type of chromosomes as the parent cell.

During telophase, a nucleolus develops in the nucleus of each daughter cell. The cytoplasm divides in the process called cytokinesis. An invagination develops and finally splits the cell into two daughter cell each with its own nucleus and cytoplasm.

Cornelius Agrippa (1486-1535) was a German mystic who practiced a "science" that combined alchemy, magic, mysticism, and astrology. Two of his books are Three Books of Occult Philosophy and On Calling Spirits. Through the writing of Agrippa, Frankenstein becomes very interested in alchemy, which is a pseudoscience whose main object is to find a way of turning base metals into gold. You could say that Frankenstein adapted the thinking of the alchemists and instead of transforming other metals into gold attempted to transform a corpse into a living being.

An interesting story about Agrippa concerns sightings of him after his death:

There were rumors that Agrippa had summoned demons on his death bed, and that a black dog roamed the countryside as his familiar. The black dog appears in tales as Faustus, Mephistopheles, and even as a grim in the Harry Potter series.
