The answer to this question is the mitotic spindle. The
mitotic spindle is also called as the spindle fibers. Mitotic spindle is a
structure of eukaryotic cells that are formed during cell division wherein the
parent cells are divided into more cells. Components of mitotic spindle consist
of large number of proteins.
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.
Homeostasis is the process by which organisms maintain internal environment constant. Anaplasia is the lack of differentiation of neoplastic cells. Histology is the study of the microscopic structures of tissues and a histologist is a person who has studied histology. Atresia is the absence of a normal opening or failure of a structure to be tubular. Therefore the correct answer is Homeostasis
The major difference between lactic acid and alcohol fermentation is the products that are produced. In the 'L.A' fermentation, lactic acid and 150 kJ of energy is produced while in alcohol fermentation, alongside the alcohol (ethanol) and the 210 kJ of energy, carbon dioxide is produced.
In lactic acid fermentation:
C₆H₁₂O₆ ₋₋₋₋₋₋₋₋> 2C₃H₆O₃ + Δ150 kJ
while in alcohol fermentation:
C₆H₁₂O₆ -----------> 2C₂H₅OH + 2CO₂ + Δ210 kJ
Meiosis.
Meiosis gives crossing over genes causing the organism to have genetic variety
