Answer:
Un potencial de acción ocurre cuando una neurona envía información a un axón, lejos del cuerpo celular. Los neurocientíficos usan otras palabras, como un "pico" o un "impulso" para el potencial de acción. El potencial de acción es una explosión de actividad eléctrica creada por una corriente de despolarización.

Explanation:
Answer:
The answer is A.
Explanation:
The arrows represents being eaten by other organisms.
(Correct me if I am wrong)
The answer is B. They bring oxygen from the air into the body.
The lungs don’t produce or release oxygen so it’s not A. or D. The lungs do not transform oxygen into carbon dioxide cause our bodies need oxygen not carbon dioxide so it’s not C. Hope this helps!
Answer:
Each protein with a specific structure and function
The unique three dimensional shape of proteins is based on several superimposed levels of structure
Explanation:
Proteins are essential nutrients for human and a vital source of fuel for building body tissues. They are made up of amino acids linked together by peptide bonds. These amino acids act as precursor to nucleic acids, hormones, immune, repair of tissues among others.
Proteins contain 20 amino acids which are the building block for proteins. These amino acids can be reformed to create millions of protein in human body in which each protein has specific structure and function.
The three dimensional arrangement of atoms in an amino acid chain is know as the protein structure. The precise shape formed determine the protein function.
