The single-celled ciliated organism Tetrahymena uses a different set of proteins for respiration from plants, animals or yeast, a new study shows. The findings reveal unsuspected diversity in how ...

It has fewer than 10 cells, lives within the muscles of salmon and doesn't have mitochondria. It sounds like science fiction, but researchers say they've recently discovered the first-ever "animal" ...

An unusual species of parasite was recently discovered by scientists. The tiny parasite hides in the muscles of salmon and has less than 10 cells. And most peculiar, the species, Henneguya salminicola ...

Yeast was used because it is a unicellular organism in the Fungi Kingdom The Next Generation Science Standards (NGSS) emphasize teaching cellular respiration as part of a unit on ecosystems If you’ve ...

Respiration is the physiological process through which oxygen in the environment can be exchanged with carbon dioxide from an organism. This process requires specialized organs such as the lungs or ...

Researchers have discovered the only known animal that does not need oxygen to survive, a common parasite that largely preys on salmon. The study, published Tuesday in the journal Proceedings of the ...

Vol. 95, No. 1, White on Green: Under-Snow Microbial Processes and Trace Gas Fluxes through Snow, Niwot Ridge, Colorado Front Range (Aug., 2009), pp. 13-21 (9 pages) Numerous studies have demonstrated ...

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration -- using oxygen to generate cellular energy -- differently from other organisms such as ...
