Biology
Why is it important for biologist to classify organism into groups?
Placed into groups so that organisms are easier to study
which kingdom include only heterotrophs?
Fungi and animals
How are bacterial cell different from the cells of other kinds of organism?
Bacteria are prokaryotes. The genetic material in their cells is not contained in a nucleus, other kinds of organisms have eukaryotes
does a virus have a nucleus?
No, and they cant treat you.
Explain Linneus's contribution to taxonomy
He wrote description of organism from his observation, placed organism into groups. he devised a naming system called binomial nomenclature
How is bacteria cells different from the cells of other kinds of organisms?
Bacteria are prokaryotes. The genetic material in their cells is not contained in a nucleus, other kinds of organisms have eukearyotes
List 4 ways in which bacteria interact with people.
1. Involved in fuel
2. food production
3. recycling
4. clean-up
How is organisms evolutionary history related to the way in which is classified ?
It's history the way its classified
what happens during binary fission?
Bacteria reproduces by binary fission a process in which one cell divides to form two identical cells.
Explain why viruses are considered non-living
Biologists consider viruses to be non-living because viruses are not cells. Viruses do not use energy to grow or to respond to their surroundings
List the 6 kingdoms into which all organisms are classified.
1. archaebacteria, eubacteria, protists, fungi, plants and animals.
What is Binary fission?
is a form of asexual reproduction process that involves only on parent and produces offspring that are identical to the parent.
Describe the basic structure of a virus
all viruses have 2 basic parts. An outer coat that protects the virus and inner core made of genetic material
which two kingdoms include only prokaryotes?
Archaebacteria and Eubacteria
Why are some foods, such as milk, heated to high tempretures before they are bottled?
To kill bacteria
Describe how viruses multiply.
Once inside, a virus's genetic material takes over the cell's function. The genetics' material directs the cell to produce the virus proteins and genetic material. These proteins and genetic material are then assembled into new virus.
