They require an centrosome and a lysosmes
<span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them.
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
Sorry its so long but that the answer i think >:) ur welcome

Answer:
Alternation of generations in plants permits both mitosis and meiosis but at different stages.
The zygote will undergo many rounds of <u>mitosis</u> and give rise to a diploid multicellular plant called a sporophyte. Specialized cells of the sporophyte will undergo <u>meiosis</u> and produce haploid spores.
Hope it helps,
I'm not so sure.
False
Mutations can form and be predicted
Depending on the situation
