Nondisjunction is defined as the failure of the chromosomes to seperate during cell division. An animal with a haploid number of 6 (diploid number of 12) undergoes meiosis, and at the meiosis II (cells are already haploid from the meiosis I), nondisjunction occurs. The mature ovum will contain 6+1 chromosomes (n+1) because there is an extra chromosome from the nondisjunction. The second polar body will contain 5 chromosomes (normal would be 6) because the second polar body did not receive that extra chromosome due to nondisjunction. In the event of fertilization of the abnormal ovum with a normal sperm, the zygote will be a diploid (12 chromosomes) normally but since the ovum as an extra chromosome from the nondisjunction then the zygote will have an extra chromosome (13 chromosomes). One pair of chromosomes has an extra single chromosome and this is called a trisomy.
Armed victims are twice as likely to be killed by an assailant as unarmed victims. Because an armed person is most likely to be more dangerous than an armed person. If engaged in an action with an armed person they are most likely to be killed because they tend to fight back rather than surrender to the authorities.
<span>Studies have shown that a number of psychological factors might predispose an athlete to an acute injury. Different people have different “mind-sets” for the competition and intensity of exercise or sports. If you’re overly “psyched out” by the importance you place on the number of repetitions you can do or the number of games you win, or if the environmental conditions in which you must perform aren’t ideal (“it’s too windy/cold/hot”), your psychological state could detract from your performance and put you at risk for injury. If you’re already injured and are still engaging in activity, this, too, can be a distraction that puts you at greater risk.</span>
The ECG machine will read the electrical charges from the electrode and the location of the electrode will influence the readings.
Lead V6 used for examining the left part of the heart and that is why it was put on the leftmost side.
If the electrode is not placed correctly the reading might be disturbed, leading to wrong examination result. The consequence of the incorrect placement would be the patient got wrongly diagnosed. The result might fail to diagnose existing disease or make a normal ECG become pathological.
