First, prophase this is when the chromosomes are just chillin in the nucleus that is protected by the nuclear envelope(the purple circle in the blue circle).
Then, metaphase this is when the nuclear envelope breaks down and the chromosomes line up on the metaphase plate in a line.
Then, anaphase this is when the two chromatids that make up one chromosome are pulled apart by spindles.
Then, telophase this is when the spit chromatids start to form new nucleus and causing the cleavage furrow, the line in between the cells that holds them together, to form.
Finally Cytokinesis, this is where you finally get your too new cells.
Answer:
Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
Explanation:
Primary succession occurs in essentially lifeless areas while secondary succession happens where there were previous communities
they both have a circular chromosome of DNA inside their cells
Upper mantle, lower mantle. idk the third
