Capsid is the component of a virus that is lacking in its cell
A capsid is the protein shell that surrounds a virus. Capsids functions by protecting the nucleic acids of a virus while interacting with the host environment. Capsids are made up of many oligomeric structural subunits that contains the protein; protomers. Capsids are generally grouped based on their structure. The common ones are helical and icosahedral.

Answer: The hypothesis can be completed as-
If the type of food available changes, then the frequency of beak also changes.
Explanation-
Natural selection is a theory of evolution that was given by Charle's Darwin. According to this theory, organisms that are capable of adapting themselves ( that is having beneficial traits, which enhance their survival) in the changing environmental conditions survive and increase their number by means of reproduction.
According to the information given in this question, the type of food available is changing, which will result in the change in the frequency of bird beaks inhabiting that area. This would indicate their adaptation so as to survive under the changed food type, otherwise they will be unable to consume the food resources and will die out.
