Answer: B. The smallest part of an atom
Explanation:
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Antibodies bind to the antigens on the surface of disease agents. If some sort of fluorescent tag is added to the antibody it would make the disease agent be identifiable either under a microscope or with other Instruments because it would bind to the antigens on the surface of the disease agents and make them glow a certain color. I hope that this is the answer that you were looking for and it has helped you.
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
A redshift is when light or other electromagnetic radiation from an object moves away from the observer.
I am not entirely sure, but i think it would be the respiratory system because plants produce oxygen after taking in carbon dioxide, and that is similar to the human respiratory system. I am not completely sure though. hope this helps!
