Which term describes the stage at which cohesins disappear and allow the centromeres to move apart in animal cells?

Explanation:

Anaphase includes two major events:

Prior to anaphase securin binds to separase and inhibits its activity

The APC with specificity factor cdc 20 targets securin for polyubiquitination which then degraded by proteasome

The released separase becomes active and then breaks the cross link(bridge) between sister chromatids

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
