What happens if a sponge breaks in half




















We've all been there. In my restaurant-industry days, I was once was making a Thanksgiving tart for a customer. When I went to unmold it, I lost control of the pan. The tart went somersaulting down, down, down, until half of it made contact with the kitchen counter and the other half landed squarely on the ground. I didn't have time to restart, but luckily I had a second tart—intended for my sister—that I sold off.

My sister had to make do with what I could piece together from the counter. The counters had been cleaned before the collision and the floor tart went to the trash, of course.

But all was not lost. I broke up any crust that wasn't already broken and tossed the bits with toasted pecans. I layered that crumble with every spoonful of the pumpkin mousse filling that I could recover and some quickly-whipped bourbon-spiked cream.

I garnished the whole mess with candied cranberries leftover from a different project. My sister still thinks it was one of the best Thanksgiving desserts she's ever eaten.

To paraphrase Spiderman, with great loss comes great opportunity. A broken cake or tart or pie may not be a huge disaster in the grand scheme, but it's pretty damn upsetting when it happens to you. Here are a few way to make the best of a broken situation:. Like that layered dessert I mentioned above, it's easy to turn a broken cake into trifle. Just grab a clear bowl or trifle dish —or even individual dessert glasses.

Break the cake up into pieces that are roughly the same size and tile them across the bottom of your chosen vessel. Type keyword s to search. Today's Top Stories.

The evolution of multi cellular sponges from single-celled protozoa is one of the landmark events in evolution. This is the origin of the Metazoa, or multicellular organisms Dawkins An experiment performed by H.

He separated the cells of a living sponge by forcing it through a fine sieve. The separated cells were let out onto a saucer containing sea-water. Most of them were single cells. After a while Wilson observed that the cells behaved like individual beings or amoebas.

They were crawling on the bottom of the saucer, and they started joining up to form agglomerations of cells. Eventually they grew to become whole new sponges.

When Wilson tried to mash up two different species of sponges together, the separated cells mixed only with their own species. They did not mix with the other kind of species.

This experiment may shed some light on how multi cellular animals formed initially. The first sponge may have been a colony of protozoans that happened to be together by chance Dawkins The cell layers are loose conglomaration of cells.

They are not really tissues as they are unspecialized. The colonial protists called choanoflagellates live in the bottom of ponds and shallow areas. Biologists think that sponge choanocytes are very similar to choanoflagellate cells, and they believe that it is highly likely that sponges arose from choanoflagalllates that lived in late Precambrian seas.

Biologists believe that the molecular evidence points to ancient choanoflagallates as close relatives of the ancestor of all animals.
