Which comparison of Bacteria, Fungus, and Viruses is the MOST accurate?
The all depend on living hosts to survive.
You can see all three without a microscope.
There are no good uses for Bacteria, Fungus, and Viruses
The all can cause disease and be harmful to humans.
If a new infection happens in a city and many people become sick, health officials may inform people about how to prevent the further spread of the disease. Which of the following is the MOST useful for this purpose?
how the disease p
long term effects of the disease
rarest symptoms of the disease
time until a vaccine is available
The human body's defense system uses cells that have different functions to fight against pathogens (germs). Which of the pictures attacks pathogens and other foreign particles?
Vaccinations can help build immunity and stimulate the body to make an immune response. What is a vaccine?
red blood
whitte blood cells
memory cells
dead or weakened pathogens
Sharon had been ill for five days. When her mother took her to the doctor, the doctor decided not to prescribe an antibiotic; he said Sharon had a virus. Why did the doctor NOT prescribe an antibiotic?
antiobiotics target only white blood cells
antibiotics are not used to fightn
antibiotics cause fevers that make viruses stronger.
antibiotics killl some bacteria and fungi, but are unable to treat viruses
Malaria, a type of parasite, infects 500 million people yearly by infecting the red blood cells of its host. The Influenza virus reports one billion newly infected people yearly. Which statement best differentiates the pathogens, parasites, and viruses?
All rely on other living organisms to survive; but viruses are usually beneficial.
All rely on other living organisms to survive, but parasites feed on the host organisms.
All are living organisms, but parasites depend on the cells of living organisms to reproduce
All are living organisms, but viruses break down dead plants and animals that other organisms use.
The human body system has various organ systems that coordinate their functions to maintain the health of the human body. In the diagram, the larger cell on the right is a white blood cell; the smaller cells on the left are bacteria. How does this diagram show the coordination (teamwork) of the Immune System and Nervous System?
The nervous system responded to the existence of an infection and alerted the immune system to produce more bacteria cells.
The immune system responded to the presence of bacteria cells and alerted the nervous system to reduce the presence of white blood d
The immune system responded to an infection cause by bacteria and alerted the nervous system to increase the production of white b
The nervous system responded to an infection caused by bacteria and alerted the immune system to increase the productiton of white blood cells.
How do tears keep pathogens (germs) out of the human body?
They wash away pathogens from the eyes and face.
They trap pathogens inside slick membranes
They bind to specific antigens on a pathogen's surf
They raise the human body temperature to cause a high fever.
The bacteria, Escherichia coli (E. coli), are shown in the illustration. Some strains (types) of these bacteria cause diseases. Which term BEST describes these organisms?
gen
muta
pathogens
viruses
The data table details the life of the influenza virus, including the time it takes and the symptoms a human host experiences. Which statement BEST describes the correct order of human body system interactions taking place during the infection?
Lung-->
Blood -->
Antibody
Respiratory-->
Circulatory-->
Immune

Whooping cough is the common name for the disease Pertussis. The graph shows the number of cases of whooping cough that occurred in Sydney, Australia during the first half of 2005. Which group had the HIGHEST rate of whooping cough?
Males, ages 10-14
Males, Ages 30-34
Females, Ages 30-34
Females, Ages 60-64
Bill has athlete's foot. After he walks barefoot through the locker room, his teammate Carlos contracts the disease. Which description tells what happened?
Bill transmitted a fungal infection to Carlos through a contaminated object.
Bill passed a bacterial infection to Carlos through contaminated food
Carlos caught a viral infection from Bill through person to person trans
Carlos caught a parasitic infection from Bill through animal to person transmission.

Bacteri
Fu
Parasite
Virus
Which mode of infectious disease transmission is shown in the picture?
animal to person
person to person
contaminated object
contaminated food

What is one main difference between Bacteria and Viruses?
Bacteria is living; viruses are non-living
Bacteria cannot cause disease; viruses can cause disease
Bacteria cannot cause the common cold; viruses cause food poisoning
Bacteria cannot reproduce; viruses can reproduce by invading a host cell
