The answer to this question is B
<span>Intercalated discs have a function in connecting individual heart muscle cells (cardiomyocytes) and making them work as a single functional organ or syncytium. As a result, the contraction of cardiac tissue is synchronized. </span> <span>Intercalated discs are transverse bands that separate the adjacent ends in cardiomyocytes and appear as stained irregular lines at 90 degrees to the striped sarcomeres.</span>
1. what clue to the presence of certain genetic disorders can be seen in karyotype? 2. why might a lab worker attempting to diagnose a genetic disorder prefer to work with photographs of chromosomes rather than the chromosome themselves? 3.why would it be much difficult to construct a karyotype of unstained chromosomes?
Answer:
The dispersion pattern of the population depends on the type of the population and their distribution in the environment. Different types of dispersion are uniform, random and clumped.
The uniform dispersion occur when the population is evenly spaced out in the area. Random dispersion is independent of the other individuals and randomly spaced. Clumped dispersion is greatly influenced by the behavior and the resources. Population are present in small patches.
Answer:
Option B, After cleavage of the nucleoplasmin protein, only the tail segments appeared in the nucleus
Explanation:
Cleaving of nuclear localization signals occurs before the transportation into the nucleus. Before that it is responsible for sending nuclear protein continuously after every cell division leaving very little protein in the cytoplasm. Once the cleaving occurs, the nuclear localization signals, no more protein can be transmitted thereby leaving very little protein tail segments in the nucleus. Also the signal sequences on the proteins are removed once they are trans located.
Hence, option B is correct
