Answer: Fungi cell walls is composed of a mixture of chitins and beta- glucans.
In Zygomycota, asexual reproduction occurs by asexual spores in the sporangia, producing Sporangiospores.
Explanation:
Fungi are group of microorganisms that are neither plants or animals but they are classified in their own kingdom. Examples are slimemoulds, yeasts,moulds e.t.c The cell walls are composed of chitins and beta glucans, they have no chlorophyll or photosynthetic pigment,they are eukaryotic, they are heterotrophic,they lack tissue differentiation, they reproduce by spores.
Pyhlum Zygomycota reproduce both sexually and asexually. The produce spores in sporangia called Sporangiospores.
Answer:
The correct answers are: b) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", c) "Soluble proteins that misfold and form amyloid fibrils become insoluble", and d) "Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.
