Answer: we can see the nucleus obviosly in the eukaryotic cell
The continuous, low-level extinction of species is referred to as mass extinction.
- A widespread and quick decline in the diversity of life on Earth is known as an extinction event.
- A sudden shift in the diversity and abundance of multicellular creatures serves as a telltale sign of such an occurrence. It happens when the rate of diversification outpaces the rate of extinction.
- A mass extinction event occurs when a species disappears far more quickly than it is replaced.
- This is typically understood as the loss of almost 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.
- The Cretaceous-Paleogene extinction, sometimes known as the day the dinosaurs died, is the most well-known of all the mass extinction events.
