Ptolemy was an astronomer and mathematician. He believed that the Earth was the center of the Universe. The word for earth in Greek is geo, so we call this idea a "geocentric" theory.With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the Sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it.
In unicellular organisms, the process of mitosis serves as a method or form of asexual reproduction, as organisms that are unicellular and are typically prokaryotic undergo mitosis to essentially duplicate and make additional offspring that are genetically identical clones as that of the original parent cell. Mitosis in multicellular organisms serves to replace lost, specifically damaged tissue of the organism, it also is crucial for the growth and development of the organism, as it is this particular portion of the cell cycle, when cells after growing and having their DNA duplicated can they separate and produce more and more cells.
Answer:
The correct answer will be option-Cochlear nucleus
Explanation:
Cochlear nucleus is the centre of the neurons called nucleus where the cochlear nerves or auditory nerves bring the information from the inner ear cochlea.
The cochlear nucleus is composed of two nucleus- ventral cochlear nucleus (unlayered) and dorsal cochlear nucleus( layered).
The auditory nerves bring the information to the ventral cochlear nucleus and then to the dorsal nucleus where the nucleus processes the information.
Thus, the cochlear nucleus is the correct answer.
