In addition tho the elements found in carbohydrates, proteins contain the element nitrogen. true or false.

True

Explanation:

Nitrogen is found in organic compounds in all living things, animals and plants. Proteins, for example, are giant molecules whose constituent parts are compounds containing nitrogen called amino acids. An example of a simple amino acid is aminoacetic acid, or glycine.

Proteins are polymers of amino acids that can act as enzymes, catalyzing chemical reactions. They can carry small molecules or ions; can be motor to aid movement in cells and tissues; participate in gene regulation, activating or inhibiting; are in the immune system, among hundreds of other functions. Virtually all cellular functions require proteins to mediate them.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
