Bacteria
Difference between Aerobic and anaerobic bacteria
Aerobic - Needs Oxygen
Anaerobic - Does not need oxygen
A pathogen can enter the body through...
cut, air, food
Two examples of protists
Algae & Amoeba
An agent that produces disease
Pathogen
What are the three domains of life?
Eukarya, Bacteria & Archaea
Reproductive process of bacteria
Fission (Asexual)
Write an example of two viruses
Flu, cold, chicken pox, mumps, measles, polio, dengue
This antibiotic is made from fungi
Penicillin
A 22-year-old female got a cut on her arm riding her bike. The wound is red, hot to the touch and swollen. Is it viral/bacterial and would you prescribe antibiotics?
Each fission cycle takes 5 minutes, how long would it take for 2 bacteria to become 8 bacteria?
10 minutes
Bacteria gets genetic variation through
Conjugation
What kind of immunity is a vaccine?
Acquired Immunity
List 2 positive things we get from fungi and 2 things we get from protists
Fungi - Makes food (mushroom, chocolate, bread), medicines, break down pollution
Protists - Provide habitat in algae, Used to make food like ice cream
A 62-year-old female presents symptoms of vomiting, nausea and diarrhea. She went out for sushi last night. Is her illness viral/bacterial and should you prescribe antibiotics?
Bacterial - no antibiotics for food poisoning
Mrs. Shron tests quesadilla, the ducks and the dice for bacteria by putting each in a Petri dish and agar gel. Identify an independent, dependent and control for her experiment
Independent - the item tested
Dependent - # of bacteria colonies
Control - the petri dish or agar gel
Draw and label the three shapes of bacteria
Rod, Spiral and Round
What two things to antibodies do?
1. Prevent the disease from spreading
2. Destroy the pathogen
Three characteristics of fungi
Eukaryotes, Heterotrophic and absorb nutrients through hyphae
(Explain using the words pathogen, immunity and antibodies)
Jessica should not take Waffles to the dog park, because it would be exposed to new pathogens that the dog does not have antibodies for. Once the dog is vaccinated, the dog can build up its immune system.
Mrs. Shron wants to see what pizza topping is prefered. She uses Domino's slices - mushroom, cheese and meatball. She asks people at noon to rank it 1-10 on taste. Identify the Independent, Dependent and Control.
Independent - Topping (cheese, mushroom, meatball)
Dependent - Rating of taste
Control - Domino's pizza and lunch time
How is bacteria both helpful and harmful
Helpful - helps plants obtain nitrogen, cleans up pollution with bioremediation, helps digest food, decomposes organisms into soil, helps make food
Harmful - can cause illness
How is a virus different from bacteria (list 3 ways)
Viruses are non-living, not cells, are typically contagious, are smaller than bacteria
List the four groups of fungi and an example of each
Club Fungi - Mushroom
Zygote - Moldy Bread
Imperfect - Truffles
Sac - Diaper Rash
A 12-year-old female goes to a large school, has a high fever, cough and headache. She did not have any vaccines this year. What do you suspect she has? Is it viral or bacterial and are you prescribing antibiotics?
Flu, viral, no antibiotics
Each fission cycle takes 15 minutes, how long did the fission cycle take for 5 bacteria to divide into 40 bacteria?
