The true difference between the two cells is prokaryotes
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. On the other hand, Eukaryotes are organisms consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.
Myosin and actin protein filaments attach to each other . Calcium ions release into myofibrilles . Myosin filaments pull on the actin filaments
Answer:
Mimicry
Explanation:
In mimicry, species evolve to resemble other species; in Müllerian mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defences in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight.
Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects.
