Ascientific law can be best described as an explanation of a specific relationship a series of observations with contradictory data a phenomenon which works under changing conditions a description of specific relationships under given conditions

a description of specific relationships under given conditions

Explanation:

A scientific law can be established after a series of observations have been conducted and after having obtained enough data as to be able to determine the behavior of a phenomena, whilst also taking into account specific given conditions. This can serve to describe or predict a range of natural phenomena.

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:

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
