An investigation was made of the factors which cause differences in growth rates and transformation size of bullfrog tadpoles under natural conditions. Tadpoles and algal samples were collected from two.adjacent farm pon ...

Sialic acids are involved in many cellular interactions. They can serve as an adhesion ligand or act as an inhibitor to cellular adhesion by charge repulsion or by masking potential ligands. Although sialic acids are i ...

Lucina floridana is an intertidal clam that contains intracellular, sulfur-oxidizing symbiotic bacteria in its gills. These bacteria are chemolithoautotrophic, using the energy from the oxidation of reduced sulfur comp ...
