Question 1
Which of the following are the ancestors of mitochondria?
-
AEucaryotic cells
-
BPlant cells
-
CBacteria
-
DAnimal cells
Bacteria
Mitochondria and bacterial cells share several features. Mitochondria are about the same size as bacteria, have bacteria-like ribosomes, bacteria-like chromsomes, they divide independtly of the cell in which they are found and they divide in a manner similar to that of bacterial cells.
Question 2
Which of the following would be increase your risk of getting Salmonella poisoning?
-
AConsuming foods from bulging cans.
-
BWashing your hands after handling raw meat.
-
CWashing your hands after playing with your pet snake.
-
DEating raw poultry.
Eating raw poultry.
Salmonella food poisoning is associated with the consumption of raw or undercooked foods such as poultry end eggs.
Question 3
Which of the following is associated with the greatest increase in the risk of developing a stomach ulcer?
-
AExercise
-
BAlcoholic beverage consumption
-
CStress
-
DBacterial infection
Bacterial infection
An infection with the bacterium H. pylori increases the risk of developing a stomach ulcer than any of the other choices listed here.
Question 4
Which of the following live in the human gut and produce vitamin K that our bodies absorb?
-
AAnimals
-
BBacteria
-
CPlants
-
DArchaea
Bacteria
In the gut, bacterial synthesis of vitamin K can meet about 10% - 15% of a person's need for this nutrient.
Question 5
Which of the following is a good way of increasing your risk of botulism?
-
AConsuming foods procured from bulging cans.
-
BNot washing your hands before eating.
-
CConsuming raw red meat.
-
DConsuming raw eggs.
Consuming foods procured from bulging cans.
A bulging can indicates that air has gotten into the can and the bacteria responsible for causing botulism (food poisoning) are metabolically active.
Question 6
Why shouldn't infants be given honey?
-
AThey will develop an aversion to eating fruit.
-
BIt increases their risk of getting botulism.
-
CIt increases their risk of being underweight.
-
DIt increases their risk of a Salmonella infection.
It increases their risk of getting botulism.
Honey may contain Clostridium botulinum spores and should not be consumed by anyone with an underdeveloped or impaired immune system.
Question 7
Botox works because _____.
-
Ait dissolves fat
-
Bis kills the muscles responsible for wrinkles
-
Cit prevents nerves from signaling muscles to contract
-
Dit stimulates muscle contraction
it prevents nerves from signaling muscles to contract
Isn't it ironic, a toxin that results in muscle paralysis is used to make a person look younger.
Question 8
Which of the following types of cells lack a nucleus?
-
APlant
-
BAnimal
-
CFungi
-
DBacteria
Bacteria
Bacteria and archaea are both procaryotic cells, cells that lack a nucleus.
Question 9
Which of the following is not one of the common shapes of bacteria?
-
ASphere
-
BRod
-
CSpiral
-
DSquare
Square
The three common shapes of bacteria are spheres, rods, and spirals.
Question 10
The oldest evidence of life is that of fossil _____.
-
Aarchaea
-
Banimals
-
Cplants
-
Dbacteria
bacteria
Fossil cyanobacteria (blue-green bacteria) have been dated to have lived at least 3.5 billion years ago.
Question 11
Which of the following makes nitrogen available to plants?
-
AAnimals
-
BOther plants
-
CFungi
-
DBacteria
Bacteria
There are bacteria and plants that live in a mutualistic relationship in which the bacteria make nitrogen available to the plant and the plant provide the bacteria with organic nutrients.
Question 12
Which of the following are the ancestors of chloroplasts?
-
APlant cells
-
BAnimal cells
-
CFungal cells
-
DBacteria
Bacteria
Chloroplasts are very similar in structure and function to cyanobacteria (blue-green bacteria). Chloroplasts and bacteria also share some features that are common to many bacteria. Chloroplasts are about the same size as bacteria, have bacteria-like ribosomes, bacteria-like chromosomes, they divide independently of the cell in which they are found and they divide in a manner similar to that of bacterial cells.
Question 13
What are "superbugs"?
-
ABacterial that can fly.
-
BBacteria that are resistant to all, or nearly all, known antibiotics.
-
CBacteria that are capable of doing a phenomenal number of pushups.
-
DBacterial with x-ray vision.
Bacteria that are resistant to all, or nearly all, known antibiotics.
The spread of antibiotic resistance has been the direct result of human stupidity. Humans have been reckless in their use of antibiotics and are now paying the price for this recklessness.
Question 14
The bacteria responsible for anthrax are usually found living in _____.
-
Awater
-
Bintestines
-
Cair
-
Dsoil
soil
The bacterium responsible for anthrax is normally found in the soil. From the soil, it can make its way into people by variuous vectors such as contaminated animals and water.
Question 15
Chlamydia is most commonly spread by _____.
-
Asex
-
Brolling around in contaminated dirt
-
Cdrinking contaminated water
-
Dconsumining contaminated food
sex
Chlamydia is a common STD that can be spread by vaginal, oral, or anal sex.
Question 16
Coliform bacteria in water provides evidence that the water has been contaminated _____.
-
Aby acid rain
-
Bwith nuclear waste
-
Cby fertilizer run-off
-
Dwith fecal matter
with fecal matter
Water used by people is, or should be, regularly tested for the presence of coliform bacteria.
Question 17
Which of the following promote tooth decay?
-
ABacteria
-
BFungi
-
CAnimals
-
DPlants
Bacteria
The acids produced as a by-product of bacterial metabolism will promote the demineralization of teeth.
Question 18
Yogurt is the product of bacteria fermenting _____.
-
Amilk
-
Bcheese
-
Cbread
-
Doil
milk
Yogurt is produced as a result of certain bacteria fermenting milk. Yum, bacterial waste products.
Question 19
There are substances in breast milk that promote the growth of certain bacteria in the infant's ______.
-
AGut
-
BLegs
-
CFace
-
DFat

That breast milk promotes the establishment of certain bacterial strains within an infant's gut provides further evidence for the importance of these bacteria to human health and survival.
Question 20
Which of the following would survive even if all other life on the planet were wiped out?
-
APlants
-
BBacteria
-
CFungi
-
DCockroaches
Bacteria
Bacteria are capable of producing organic matter (they can feed themselves) as well as recycling organic matter back into inorganic nutrients (decomposition). Even plants, which can make their own food, are ultimately dependent on material for the nitrogen they need to do so.
