During metaphase 1, the spindle fibers attach to the centromeres of each chromosome. Both kinetochores of each sister chromatid pair are turned toward the same pole. And 2 members of each chromosome pair (sister chromatids) are pulled into each new cell during anaphase 1.
I think the answer you want is they are called chromatids.
I believe that all members of one species form a population.
<span> d/ They create small currents in their microenvironment that help to circulate and clean water locally for other organisms.</span>
Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.
Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution
<h3>What is Fahrenholz's rule ?</h3>
The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.
This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.
when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.

thats dirty bruh but you could filter all the dirty stuff out and reuse the water
