There isn’t exactly a name for it other than “folded sarcolemma”, however, the end of the motor neuron does extend some projections into these spaces.
Food webs with fewer species are more sensitive to the loss of species and ecosystem disturbances
Explanation:
When connected together by series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on other interactions (dashed lines) between its amino acid side chains.
That would be ascomycota or sac fungi. Sac fungi are characteristically known for producing ascus. This is a sac-like structure that contains haploid spores called ascospores. Some examples of sac fungi are yeast, truffles, morels and dead man's fingers.
