An outbreak of a disease that affects many people in an area.
What is Epidemic
A drug that kills or slows the growth of bacteria
What is Antibiotic
A symbiotic relationship in which one organism benefits and the other neither benefits nor is harmed
What is Commensalism
The joining of an egg and a sperm to form a zygote
What is Fertilization
An organism that transmits a disease.
What is Vector
An epidemic that spreads over a large area or throughout the world.
What is Pandemic
An organism that lives on or in another organism and benefits at the organism’s expense.
What is Parasite
A symbiotic relationship in which one organism benefits and the other is harmed
What is Parasitism
Organisms whose cells have a distinct nucleus and organelles
What are Eukaryotes
A weakened or dead form of a pathogen
What is Vaccine
A specialized cell (sperm or egg) used for reproduction (has half the number of chromosomes)
What is Gamete
Is the process by which cells of plants and some other organisms use the energy of sunlight to make food
Carbon dioxide + Water Glucose + Oxygen
6CO2 + 6H2O -----------> C6H12O6 + 6O2
sunlight
What is Photosynthesis
A symbiotic relationship between two organisms in which both organisms both benefit.
Mutualism
The process of reproduction that involves only one parent and produces offspring genetically identical to the parent (growing from eyes/buds Ex. potatoes, strawberries from runners)
What is Asexual Reproduction

What are Bacteria are living organisms, but viruses are not
The process that converts nitrogen in the atmosphere into compounds in the soil that are useful to a variety of organisms.
What is Nitrogen Fixation
The process by which cells breaks down sugar to release stored energy
Glucose + Oxygen —-----------> Energy + Carbon dioxide + Water
C6H12O6 + 6O2 -------> ATP + 6CO2 + 6H2O
Cellular Respiration
Diseases that are passed from one organism to another.
