The human body comprises of more than 600 muscles differentiated in three classifications, and all are under the control of the nervous system. The activities like picking up a dropped pen or leaning over incorporate the combined effort of various muscle groups.
The alert mind relays this instruction to the central nervous system that conducts it in the form of electrical impulses. These are then mediated via the somatic segment of the peripheral nervous system to the nerves accountable for monitoring the essential muscles.
When the signals arrive, a chemical known as acetylcholine gets discharged from the nerve terminals, activating the membranes of muscle fibers and making them to contract. The receptors present in the muscles provide the brain with the instruction regarding the movement and position of the body, the brain monitors the contraction of skeletal muscles.
Binary fission is a type of asexual reproduction in which a cell divides to form two cells. It occurs in organisms that are protozoans. This means that two new daughter cells are formed in the process.
During the process of binary fission, the cell Is divided into two, this means that the DNA is replicated in both parts so that each of these cells becomes an independent organism, this means that they would be able to survive and function on their own.
Hence from the options listed, binary fission is observed in Amoeba
In short, translation is the synthesis of proteins by ribosomes in the cell. It follows after the process of transcription in which a molecule of mRNA is copied from DNA to produce a specific base sequence. ... This process is repeated until a stop codon on the mRNA is reached and the completed polypeptide is released.
