When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.
Option two of the question states that the cell cycle will <u>proceed uncontrollably, this is not the case for the error at hand</u>. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment. As is the case with options 3 and 4.
The stop or delay in the <u>cell cycle is what normally takes place in these situations.</u> This stoppage is done by the <em><u>spindle checkpoint</u></em>, which prevents <u>duplicate chromosomes from separating.</u>
During this time, the error it's corrected. If a cell is not able to correct the error at this time, many situations can follow. <u>However, the most likely is that the cell will undergo a <em>programmed cellular death.</em> </u>

Answer:
c. mitochondrion, virus, hemoglobin, glucose, water molecule
Explanation:
The mitochondrion is a membrane which is found in cytoplasm of eukaryotic cells. It is also known as power house of cells. This is largest from virus, hemoglobin, water molecule and glucose.
Virus is second largest and is small infectious agent. It has capability to infect many organisms and living cells. Hemoglobin is protein which is present in red blood cells. Glucose is a type of sugar presence in the blood. Water molecule is composed of hydrogen and oxygen and is smallest among the others.
The type of muscle that is responsible for maintain posture is VOLUNTARY. The correct option is B. Skeletal muscles are the ones who control posture and movement and they are voluntary in nature, that is, they are under the conscious control of man. The muscles that are responsible for maintain posture are: spinal, pelvic and abdominal muscles, hip muscles, lower leg muscles and shoulder and neck muscles.
