you design an experiment to test the effects of various salt concentrations on a protein to determine where it will precipitate. for consistency, you must keep the protein concentration constant across samples. in this experiment, the salt concentration is the

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

archaebacteria are found in in forest soil.
