The answer is Protista.
The dichotomous key is used to identify the taxonomic category of an organism. So, if we start with statements from the beginning, and discard the possibilities, we can put the organism into some taxonomic group.
Accordingly, we know that a stentor has a nucleus, so it must be eukaryotic. Among the Eukaryotes, it could belong to the kingdom of Protista, Fungi, Plantae and Animalia. Since it is unicellular organism and lives only in the water, it could belong only to the kingdom of Protista
A microbe that grows only at the bottom of a tube of thioglycollate medium is probably a(n) <u>obligate anaerobes</u>.
Thioglycolate broth would be a versatile enrichment and differential medium that is largely used to ascertain the oxygen needs of bacteria. Obligate anaerobes can grow because of the oxygen-consuming properties of sodium thioglycolate inside the medium.
A variety of oxygen concentrations are produced in the medium across its depth as a result of this and the diffusion of even more oxygen as from broth's surface.
Because oxygen would be poisonous to obligate anaerobes, they congregate near the tube's bottom where another oxygen level is lowest.

Stamen is composed of anther and filament. The pistil is composed of stigma, style, and ovary. ... The key difference between stamen and pistil is that stamen is the male reproductive organ which produces pollens of angiosperms while pistil is the female reproductive organ which produces ovules of angiosperms.
