|
|
|
Lives in harsh environments, no peptioglycon
|
Archaebacteria
|
|
|

|
|
|
How do scientists tell the differences between two strains of bacteria that look alike?
|
"Gram Straining"
|
|
|
Name some ways that Bacteria can help you:
|
Making Energy, Decompose, Helps Digestion, Cleans up oil spills, breaks down leftovers and metabolizes them, creates food, fertilizes plants, etc etc.
|
|
|
How can bacteria be harmful to you?
|
It can start infections. Also, tuberculosis, salmonella, E Colli, etc.
|
|
|
What is the medicine called that you can take to kill a bacterial infection?
|
Antibiotics
|
|
|
How can we prevent bacterial infections?
|
Make sure your doctors are sanitized and gloved, wash your hands with soap and warm water instead of constant use of hand sanitizer, and stay away from raw or uncooked foods.
|
|
|
How can we grow bacteria in a controlled environment?
|
Find a dark and moist environment with warm temperatures.
|
|
|
What type of environment could that be?
|
A closed, dark space underground, such as a cave in Florida or a murky subway. Also, dish washers and hot tubs.
|
|
|
Figuring out the type of bacteria
|
Gram Straining
|
|
|
If some types of Eubacteria can have a second cell membrane to resist damage, why can that be a bad thing?
|
They may not be able to die as easily which can increase the amount of time an infection invades the body, and the amount of time to fight it off will be longer.
|
|
|
a sexual reproduction
|
Binary Fission
|
|
|
genetic information is passed from 1 to 2, but a "baby", or offspring, is not made.
|
Conjugation
|
|
|
Encloses DNA and waits for a more favorable condition
|
Spore Formation
|
|
|
Slows down the metabolism of an animal during the cold winter months
|
Hibernation
|
|
|
Are spore formation and hibernation the same thing?
|
They use a similar preservation idea.
|
|
|
Aids in digestion, helps create foods
|
"Helps"
|
|
|
Gets rid of dead organic material
|
Decomposers
|
|
|
Helps fertilize plants, some bacteria can "eat" oil from spills
|
Nitrogen Fixers
|
