What part of the ear is responsible for converting sound into nerve impulses?

Back

Cochlea.

Front

What is the term for the material through which a wave travels?

Back

Medium.

Front

What is the relationship between frequency and pitch?

Back

The higher the frequency, the higher the pitch.

Front

What is the evidence in the statement: 'You should eat a banana every day. Bananas have nutrients like potassium and magnesium. Because our bodies need potassium and magnesium to work, it is a good idea to eat a banana every day.'?

Back

Bananas have nutrients like potassium and magnesium.
