Scientists use various types of models to represent real world activity. for instance, computer models are used to predict weather patterns, and the physical models of thomson and rutherford have been used to us understand the structure of the atom. scientific models like this are useful because they can to describe and predict natural behavior. however, such models are limited, anda. they in no way reflect the natural worldb. their predictions are almost never accuratec. their predictions are not accurate every single timed. they can only be used by experienced scientists to make relevant predictions

(B.) their predictions are almost never accurate

Explanation:

A model is a representation of an idea, process that scientists use in explaining a complex data to a more simple and understable way. Models reflect the natural world e.g. climate models are used by humans to learn and to know about carbon cycles, water cycles and the weather. Model do come with some limitations one of them is an incomplete detail e.g. measuring the distance round the earth, we were made to believe that the model of the Earth is spherical, so in calculating the distance round the earth certain details are missing like the variations in distance caused by valleys and mountains and other topological problems that might be encountered.

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.
