You need your Science Notebook. Open to the next page after the notes from yesterday.

2. 1. MICROORGANISM
What it is.. Any organism too small to be viewed by the unaided eye. Examples: bacteria or some fungi and algae.

3. 2. DISEASE
What it is.. A condition of an organ, or system of an organism. A disease may result from various causes such as: infection, genetic defect, or environmental stress. Diseases are characterized by an identifiable group of signs or symptoms. Examples: Cancer, Malaria, or Ebola

4. 3. BACTERIA
What it is… A very large group of microorganisms comprising one of the three domains of living organisms. They are prokaryotic, unicellular, and either free-living in soil or water or parasites of plants or animals. Examples: E. coli and Staphylococcus

5. 4. VIRUS
What it is… An extremely small living thing that causes a disease and that spreads from one person or animal to another. Examples: Rhino Virus - Common cold or a flu virus

6. 5. MALARIA
What it is.. Malaria is a disease that is spread by the bite of an infected Anopheles mosquito. Malaria symptoms include fever, chills, and nausea. Examples OR CONNECTIONS: Malaria is a deadly disease just as small pox was before vaccine protection.

7. 6. PARASITES
What it is… A plant or an animal organism that lives in or on another and takes its nourishment from that other organism. Examples: leech, lice, mosquitos

8. 7. VACCINE
What it is…A substance that is usually injected into a person or animal to protect against a particular disease Examples: Whooping cough vaccine, chicken pox vaccine, flu vaccine

9. 8. EBOLA
What it is… A deadly virus that causes fearsome symptoms, the most prominent being high fever and massive internal bleeding. Ebola virus kills as many as 90% of the people it infects Examples or CONNECTIONS: Ebola has a high death rate just as AIDS.

10. 9. FUNGI
What it is… Any one of a group of related plants that have no flowers and that live on dead or decaying things Examples: molds, mushrooms, or yeasts)

11. 10. PROTOZOA
What it is …Protozoans are simple organisms, or living things. Most protozoans are so tiny that they can be seen only with a microscope. Example or CONNECTIONS: They belong to a group of organisms called protists, which are neither plants nor animals.
