As noted in Section 1.5, Europa's near-infrared reflectance spectrum was used as long ago as the 1950s to demonstrate that its surface is mostly water-ice. More recently, spectroscopic observations by the Hubble Space Telescope and Galileo have revealed some regions where the ice appears to be salty (see below) and ha

It also controls the deposition of calcium in the bones during growth and maintains adult bone structure. If vitamin D is deficient, with less calcium available, the skeleton fails to develop normally. The most obvious symptom is the bowing of the leg bones in children, producing the condition called rickets (Author(s): The Open University

1. Certain minerals are required in the body.

2. Some minerals form essential structural components of tissues. For example, calcium, phosphorus and magnesium compounds are major components of bones and teeth. Fluoride is also important in protecting teeth from decay.

3. Sodium, potassium, calcium and chloride ions are important in maintaining the correct composition of cells and of the tissue fluids around them (homeostasis). These same

We ask what the relationship is
