Bacteria: (singular: bacterium) are single-celled organisms that live almost everywhere on Earth, from the bottom of the ocean to the insides of other living things (such as plants and animals). They are one of the three realms of life on Earth.
DNA: (abbreviation for deoxyribonucleic acid) is a long, double-stranded, helical molecule present in most living cells. It carries genetic instructions and is built on a backbone of phosphorus, oxygen, and carbon atoms. In all living things, from plants and animals to microorganisms, these instructions tell cells which molecules to make.
Klebsiella: is a type of bacteria that is increasingly resistant to antibiotics. Infections with this bacterium can cause pneumonia, meningitis (inflammation of the meninges, which protect the brain and spinal cord), and blood-borne diseases. It is often spread through contact with the feces of an infected person or contaminated food.
Immunity: can prevent certain infectious diseases or indicate that an organism does not show effects from exposure to a toxic substance or process. It may also mean that something cannot be harmed by a specific drug, disease, or threat.
Microorganisms: are organisms that are too small to be seen with the naked eye, including bacteria, some fungi, and other organisms like amoebas. Most microorganisms are composed of a single cell.
Microbiologist: is a scientist who studies microorganisms, the infections they can cause, or their interactions with the environment.
Microwave oven: uses electromagnetic waves with wavelengths shorter than radio waves and longer than infrared and visible light.
Radiation: is one of the three main ways energy is transferred, with electromagnetic waves carrying energy from one place to another. Unlike conduction and convection, radiation does not require matter to transfer energy and can do so through empty space.
Distortion: in biology, refers to organisms of the same species that share small but distinct characteristics. It can also mean a stretch or rupture of a muscle or tendon in medicine.
Stress: in biology, includes factors like extreme temperatures, movement, moisture, or pollution that affect the health of a species or ecosystem.
