This could be mitosis or meiosis. Meiosis produces 4 daughter cells while mitosis produces 2 daughter cells. Mitosis is used for every cell except your sperm and egg cells, in which that would be meiosis.
When the rabbit caught his head in a fan means
that it took ears off his own life. It may be related to a person who might
possibly living by his/her own means. That person may be independent in his own
way to the point that he/she may not listen to the opinion of others.
Answer:
He meant that the supporting cells form a insulating coat on the nerve fibre called myelin seath. The myelin Sheath act similar to the rubber coating of household wiring because it electrically insulates the nerve fibre and speeds of conduction of nerve impulse..
Explanation:
- The supporting cells of the nervous system are together called neuroglia or glial cells.
- Unlike neurons these cells can divide in the mature nervous system and do not conduct nerve impulse.
- Out of six types of glial cells, four are located in the central nervous system (CNS) and they are;astrocytes, oligodendrocytes, ependymal cells and microglia.
- The remaining two types are the part of Peripheral nervous system (PNS) and include Schwann cells and Sattelite cells.
- Among these , the oligodendrocytes of the CNS and Schwann cells of the PNS forms myelin sheath on the axons of the nerve cell that act similar to the rubber coating on the household wiring.
- The myelin sheath electrically insulates the axon of a neuron and increase the speed of conduction of nerve impulse.
For both actin and microtubule polymerization, nucleotide hydrolysis is important for controlling the growth of a microtubule.
Polymerization dynamics enable microtubules to adopt rapidly changing spatial arrangements and, in some cases, perform mechanical tasks according to cellular needs. Microtubules harness the energy of GTP hydrolysis to drive a unique polymerization mechanism called dynamic instability.
Microtubules are one of the main components of the cytoskeleton and are rigid hollow rods approximately 25 nm in diameter. microtubules. are made up of dimers of α- and β-tubulin which polymerize to form microtubules, which are composed of 13 protofilaments assembled around a hollow core.
