Ascientist is examining a single-celled organism with no nucleus that can be found in extreme environments. what kingdom does this organism belong to?

a. animalia
b. archaebacteria
c. eubacteria
d. protista

Archaebacteria

Explanation:

Archaebacteria are single cell organisms which can survive in extreme environments. They can be found in very hot, very cold or very salty environments. Some of them survive only in a methane atmosphere.

I think animalia

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
