The immune system<span> is made up of a chain of cells, tissues, and organs that work together to protect the body. </span>
The answer is <span>C. glycolysis, Krebs cycle, electron transport</span>
Cellular respiration includes glycolysis, link
reaction, Krebs cycle, and electron transport chain (ETC), in that order. The
main function of ETC is a production of ATP. In this series of
oxidation-reduction reactions, electrons from the previous stages of cellular
respiration are taken and transported to the oxygen which is the final acceptor
of electrons. As the result, water and ATP are produced.
Answer: protein
Explanation: protein
Amino acids link together to form a protein. A nucleic acid is held together by the sugar-phosphate complex. A protein is held together by the carbon-carbon bonds. The diagram shows the basic structure of a biomolecule.

Compared to cnidarians, bilaterally symmetrical animals have a central nervous system.
<h3>What do bilaterally symmetrical animals have?</h3>
• Bilaterally symmetrical animals have "heads" and "tails" (front and back), front and rear (back and abdomen), and left and right sides. All true animals are bilaterally symmetrical, except those with radial symmetry. The
• longitudinal nerve cords, usually in 3-5 pairs, extend posteriorly from the brain. They are connected by transverse commissures, with smaller lateral nerves extending from the cords. The peripheral plexus arises from the lateral nerve.
<h3>Do bilaterally symmetrical animals have diffuse neural networks?</h3>
Neural networks consist of interconnected neurons that lack brains or some form of cephalization. Organisms with bilateral symmetry are usually associated with neuronal compression and, in a more advanced form, with the central nervous system, whereas organisms with radial symmetry are associated with neural networks.
