5 giorni fa · Eumetazoa. Os animais incluídos no clado Eumetazoa são caracterizados por apresentarem o epitélio dividido em uma camada interna de células digestivas, a endoderme, e uma camada externa protetiva, ou dorsal, a ectoderme.
4 giorni fa · This tempts us to speculate that there is structural and functional importance of this cysteine pair between TIMM17A/B and TIMM23 across the Eumetazoa sub-kingdom. Altogether, using computational tools, we show that the presence of an intramolecular disulfide bridge in Tim17/TIMM17A/TIMM17B is conserved between yeast and humans.

2 giorni fa · Mollusca is the second-largest phylum of invertebrate animals, after Arthropoda; members are known as molluscs or mollusks [a] ( / ˈmɒləsks / ). Around 76,000 extant species of molluscs are recognized. [3] The number of fossil species is estimated between 60,000 and 100,000 additional species. [4] The proportion of undescribed species is ...
3 giorni fa · Other anatomical and biochemical evidence links the Eumetazoa with Homoscleromorpha, a sub-group of demosponges. A comparison in 2007 of nuclear DNA, excluding glass sponges and comb jellies, concluded that: Homoscleromorpha are most closely related to Eumetazoa; calcareous sponges are the next closest;
3 giorni fa · This tiny marine animal, with a size of up to 2mm, looks like an irregular “hairy plate” (“tricho plax”) whose unique bauplan is based on a simple, irregular sandwich organization. An upper and a lower epithelium surround a loose network (not an epithelium) of so-called fiber cells (Fig. 4A).
