Experts estimate that over 25,000 species become extinct each year, with some estimating this number to be over 100,000. this is
an alarming rate that threatens fragile ecosystems and global biodiversity. which of these is currently the leading cause of extinctions today?a)global climate changeb)habitat loss due to human interactionsc)development of cleaner running automobilesd)natural disasters such as volcanic eruptions and earthquakes
Habitat destruction due to human activities is one of the major cause of extinction of species of living beings. Extensive human activities such as drainage of wetlands which were otherwise habitat for frogs and alteration of the physical climate of the habitat by addition of pollution has resulted in extinction of many species. Therefore, habitat destruction by human interactions is major cause of loss of biodiversity.
In the transition of metaphase to anaphase, the cohesin complex is cleaved by the separase enzyme in a process dependent on the activation of specific proteins that trigger posttranslational modifications (i.e., protein degradation by ubiquitination). This process of cleavage enables the sister chromatids to separate and move to opposite sides of the cell
