Diseases #13
Provide 2 examples of diseases caused by each of the pathogens
100
the smallest unit of matter that still retains the properties of an element
What is an atom?
100
reactions that involve splitting the nucleus of an atom (which contains the protons and neutrons) -a nuclear reaction that occurs when a neutron strikes the nucleus of an atom and breaks it into two or more parts
What is nuclear fission?
100
energy from sources that are renewable and have a low environment impact
What is sustainable energy?
100
Advantages: local production (can grow in many different areas); can reduce waste Disadvantages: burning pollutes air, reduces land available for food production; best species for biofuels may also be invasive
What is biofuel(biomass)?
100
typhoid fever and lyme disease and vibrio
What is bacteria?
200
energy produced from organisms, such as animal waste, plants, or algae; it's another indirect form of solar energy
What is biofuel?
200
a technology that coverts solar energy directly into electricity
What is photovoltaic (PV) cells?
200
organisms that spread disease
What is a vector?
200
Advantages: useful both as source of electricity and heating/ cooling Disadvantages: building power plants is costly; only available for electricity generation in certain areas (can be used for heating and cooling anywhere)
What is geothermal energy?
200
ringworm and canidiasis
What is fungi?
300
The branch of public health that focuses on how the natural and human-built surroundings as well as behaviors affect human well-being
What is environmental health?
300
atoms that spontaneously emit subatomic particles and/or energy
What is radioactive?
300
infectious diseases ex: influenza, malaria, cholera...
What is biological hazards?
300
Advantages: dams additionally can be used for recreation, flood control, and storing freshwater Disadvantages: while operation impacts the environment minimally, building dams degrades habitat; dependent on rainfall
What is hydroelectric (hydropower)?
300
guinea worm and hook worm and elephantiasis
What is worms?
400
The amount of time that it takes for half of the original radioactive isotope to decay
What is a half-life?
400
an infectious agent that causes illness or disease
What is a pathogen?
400
exposed to toxic substances like poison, etc., and air pollutants ex: secondhand smoke, heaving metals, carbon monoxide...
What is chemical hazards?
400
Advantages: more abundant and portable than wind energy; like wind energy, creates jobs and can be stored in a battery Disadvantages: like wind energy, is only available at certain times and isn't available everywhere; more expensive than other sources of renewable energy
What is solar energy?
400
dengue and west nile virus and japanese encephalitis
What is viruses?
500
atoms of the same element that differ in neutron number but have the same number of protons
What is an isotope?
500
energy from sources that are replenished on short time scales or seemingly will always be available
What is renewable energy?
500
additional forces that can imperil humans ex. UV light, natural disasters, extreme weather, traffic accidents,...
What is physical hazards?
500
Advantages: least expensive of all renewable energy sources, creates jobs, energy can be stored in batteries
What is wind energy?
500
giardiasis and African sleeping sickness and malaria
What is protozoa?
