Vocabulary development is a process by which people acquire words. Babbling shifts towards meaningful speech as infants grow and produce their first words around the age of one year. In early word learning, infants build their vocabulary slowly. By the age of 18 months, infants can typically produce about 50 words and begin to make word combinations. In order to build their vocabularies, infants must learn about the meanings that words carry. The mapping problem asks how infants correctly learn to attach words to referents.
Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help. Balance the amount of water in your body; Balance your body's acid/base (pH) level; Move nutrients into your cells; Move wastes out of your cells
Having the right amount of electrolytes, including calcium, chloride, magnesium, potassium, sodium, and certain acids, is essential for maintaining the health of nerves and muscles, including those in the brain, heart, lungs, and other vital organs.
