In the case of chronic bronchitis or chronic inflammation of the airways, cyanosis or the bluish discoloration of the skin results from the reduced levels of oxygen in the blood. With reduced oxygen levels, the blood in the arteries will not be bright red in color but rather be brownish just like venous blood and this reflects in the skin as bluish in color.
Vesicular breathing sounds are result from or are produced because of a person's need of breathing. In order for a person to breathe, gas exchange is needed to have an oxygen to breathe and to regulate the blood flow. To do this, the lungs is needed and with the help of their components namely the aveolar sacs, which enables to fill the air in the lungs, resulting to or producing vesicular breathing.
This response that helps aerial plants find water is called evapotranspiration. It <span> is the </span>sum<span> of </span>evaporation<span> and </span>plant transpiration<span> from the Earth's land and ocean surface to the </span>atmosphere<span>. Hope this answers the question. Have a nice day. </span>
Answer:
Since sister chromatids are identical, genetic variation will not be produced in the daughter cells.
Explanation:
Sister Chromatid Exchange (SCE):
- This is a rare recombination phenomena that entails recombination and crossing over between two sister chromatids.
- This is contrary to normal recombination in which crossing over between non-sister chromatids takes place, producing genetically variable daughter cells.
- Exchange of genes between sister chromatids does not produce genetic variations.
- SCE is actually an indicator of chromosomal instability and DNA repair and replication malfunction.
- SCE is observed to be increased in pathological conditions like Bloom syndrome (genetic disorder) and Behcet disease (chronic inflammatory disorder) etc.
