How far back do probable prokaryotic cells date back to?
3.5 billion years
100
What is the term for the process by which gaseous carbon dioxide turn into solid carbon compounds?
It is called Carbon Fixation.
100
True or False? Eubacteria can clean up waste.
True-they clean up waste and oil spills.
100
Which one lives in harsher environments, Eubacteria or Archaebacteria?
Archaebacteria
200
Do archaebacteria consist of a cell wall? Explain.
Yes, but they are different than all other organisms.
200
Which theory states that eukaryotes evolved from prokaryotes like bacteria?
The endosymbiotic theory
200
True or False? if false correct the statement: Archaebacteria and Eubacteria reproduce through either meiosis or mitosis.
False, they reproduce through the asexual process called binary fission.
200
What organ system greatly benefits from the activity of Eubacteria?
The Digestive System- the stomach and intestines, the bacteria breaks down certain nutrients.
200
What do bacterias specifically produce?
Biochemicals and biomass
300
What type of life form is archaebacteria?
Archaebacteria is said to be an ancient form of life, considered the oldest life form on earth.
300
Are eukarya more closely related to archaea or eubacteria?
They are more closely related to archaea
300
How fast can E. coli bacteria double?
Within 20 minutes.
300
What allows Archaea to live other extreme conditions?
Enzymes that are unique to bacteria allow them to live in these conditions.
300
Are bacteria only decomposers? Explain.
No, they are decomposers as well as prodocers. They are vital to biogeochemical cycles.
400
What type of environmental conditions do archaebacteria inhabit in? List at least 3 conditions.
hot springs, salt lakes, marshlands, oceans, guts of ruminants and humans
400
In which two domains are hipstone proteins found?
Archaebacteria and Eukarya.
400
Name one source of energy of archaebacteria.
Sugars or metal ions or hydrogen or sunlight or carbon fixation.
400
Name two food products that cannot be made without the use of Eubacteria.
yogurt, cheese, soy sauce, chocolate
400
Explain one of the human impacts on bacteria.
Either global warming or overuse of antibiotics.
500
What is the difference between a prokaryotic cell and a eukaryotic cell?
A prokaryotic cell lacks a nucleus while a eukaryotic cell has a nucleus.
500
What is special about the mitochondria of the prokaryote?
The mitochondria has a double membrane and its own DNA. (suggesting that it could have survived alone).
500
Name two processes in which eubacteria can obtain food through.
Two processes include chemosynthesis and photosynthesis.
500
List 3 general applications of Eubacteria.
Biotechnology, Human Body, Production(food), Cleaning
500
Explain the process called conjuagation.
a process in which there is a transfer of genetic material involving two cells. This process produces cells with new genetic combinations, and thereby provides a chance that some may be better adapted to changing conditions.
