Answer:
Actually, they have all of these features
Explanation:
Sister chromatids are replicated chromosomes formed during DNA replication at the Interphase stage. Since one is a replica of the other, they are the same in lenght, alleles content and every other aspect. They are joined together at the centromere.
Sister chromatids are separated from each other into each daughter cell at the Anaphase II of meiosis II and Anaphase of mitosis specifically. Hence, they remain attached to one another by their centromere until they reach Anaphase. Every chromosome contains the telomere at their end region and it plays a vital role in ensuring that neighboring chromosomes do not join.
Answer:
Explanation:
Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere).
Answer:
They help transport materials that an organism needs to survive and they recycle waste materials.
Explanation:
I hope this helps! :))
An example of succession is a landslide is produced, then lichens grow, this leads to the accumulation of thin soil, which finally leads to a mature community.

The succession may involve the emergence of new species in the ecosystem after disturbance.
