Final answer:
Kentucky bluegrass does not have stolons; it spreads via rhizomes. Bacteroides are the most prevalent bacteria in the human gut. Among seedless vascular plants, ferns are the most diverse group.
Step-by-step explanation:
The question asks us to identify which turfgrass does not have stolons. Stolons are horizontal above-ground stems that can give rise to new plants from nodes along their length. These are important in some grasses for vegetative propagation and spreading. Among the options provided, Kentucky bluegrass (Option B) does not produce stolons. Instead, Kentucky bluegrass spreads through underground stems called rhizomes, making it different from options A, C, and D, which all utilize stolons for propagation.
To answer the other reference questions: The most prevalent bacteria in the human gut is Bacteroides (Option D). There is a vast community of microorganisms living in the human digestive system, with Bacteroides making up a significant proportion of the gut flora. They play a crucial role in processing complex molecules to simpler ones in our digestion process.
When discussing the most diverse group of seedless vascular plants, the ferns (Option D) represent the most diverse group. Ferns exhibit a great variety of habitats, forms, and reproductive strategies and are found throughout the world. They are more diverse than liverworts, horsetails, and club mosses in terms of species count and ecological adaptations.
