Response:
The skeletal system's bones collaborate with the muscular system's muscles.
Clarification: The system composed of muscles and bones allows for movement.
(I hope this is useful; you could also look for the same question as someone might have already addressed it.)

Choanoflagellates and sponges are sister groups Explanation: Choanoflagellates are tiny unicellular organisms in the kingdom Protista, morphologically akin to the choanocyte cells of sponges, featuring a central flagellum encircled by a collar of microvilli. Consequently, choanoflagellates are often regarded as the closest living relatives of primitive metazoans, thus classifying them as sister groups to sponges. Recent molecular phylogenetic and genomic studies have backed this idea.
Une cellule végétale qui apporte un soutien sans entraver la croissance, souvent reconnue sous le terme de "fibres dans le céleri", est appelée une cellule collenchyme.
