Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.
Answer:
Neurons and muscle cells perform different functions, however they have the same DNA (genetic material) contained within them.
The function of muscle cells is to mechanically contact to allow the body to move in space.
The function of nerve cells is to send and receive signals. in order to trigger an event or elicit a response.
Explanation:
The best answer is A.
The shape of a protein is determined by its primary structure. The primary structure is the sequence of amino acids in each polypeptide chain which make up a protein.
The sequence of amino acids is basically a list of amino acids that are linked to each other to form a chain which is known as a polypeptide chain.
The structure of the finished protein will depend largely on the first (primary) chain of amino acids to be produced to make up that protein.
A catalyst increase a chemical reaction, therefore making the answer B. Promotes a chemical reaction.
