Sponges have medicinal properties due to the presence of microbial chemicals that may control viruses, bacteria, tumors and fungi. They even look rather nice, and some species are helpful to humans when dried and put to use in the kitchen and bathtub.Up to 99% of the world's animal species are invertebrates.
The discover things from the past
Answer:
Delta binds to the Notch receptor and this binding produces the cleavage of its intracellular domain, which subsequently enters into the cell nucleus to bind with a repressor in order to activate the transcription
Explanation:
The Notch signaling pathway is initiated when Notch receptors on the cell surface bind to the Delta ligand, which activates Notch signaling in cells next to it. In the receiving cell, Delta–Notch binding triggers the cleavage of the Notch intracellular domain called Nic (intracellular Notch). Subsequently, Nic enters into the cell nucleus where it releases repression on Suppressor of Hairless (Su(H)) class transcription factors, thereby activating the transcription of target genes.
