What is life?
Bacteria
Viruses
Reproduction
Potpourri
100
The basic unit of structure in an organism.
What is a cell?
100
This is the jelly-like material inside the cell membrane, not the goo in "Ghostbusters."
What is cytoplasm?
100
Viruses can only multiply when they are inside this. The answer is not a bedroom.
What is a living thing?
100
When two parents combine their genetic material to produce a new organism.
What is sexual reproduction?
100
Living things arise from living things through this process. Duh.
What is reproduction?
200
These types of unicellular organisms are the most number organisms on Earth.
What are bacteria?
200
These tiny chemical factories are where proteins are produced.
What are ribosomes?
200
The name of the living thing that provides energy for a virus.
What is a host?
200
One parent reproduces offspring identical to that parent.
What is asexual reproduction?
200
Once inside a cell, a virus does this to its host.
What is takes over many of the cell's functions?
300
A change in an organism's surroundings that cause it to react.
What is a stimulus?
300
Bacteria "wave" these long, whiplike structures to move themselves. But they never salute them.
What is a flagellum?
300
Scientists consider viruses nonliving things because of these characteristics.
What are they are not cells, they do not use energy and they do not respond to their surroundings?
300
If you lived in 1776 and found mold on your bread, you would assume that the live mold formed on your nonliving bread through this process.
What is spontaneous generation?
300
The maintenance of stable internal conditions despite changes in surroundings. There's no place like ....
What is homeostasis?
400
These organisms make their own food, but they don't drive cars.
What are autotrophs?
400
Bacteria are these because their genetic material in their cells is not contained in a nucleus.
What are prokaryotes?
400
These organisms live in a host and cause harm to it.
What is a parasite?
400
Bacteria reproduced by this process, which has nothing to do with a pole, a hook and worm.
What is binary fission?
400
An organism that breaks down the large chemicals in dead organisms into smaller chemicals. This has nothing to do with Mozart or Beethoven.
What are decomposers?
500
All organisms need these four things represented by the acronym FoWLSIC.
What food, water, living space and stable internal conditions?
500
Bacteria need at least two of these things to thrive and reproduce frequently.
What are plenty of food, the right temperature and other suitable conditions?
500
These viruses infect bacteria.
What are bacteriophages?
500
When on bacterium transfers genetic material into another bacterial cell. This has nothing to do with creating different verbs.
What is conjugation?
500
When a scientist carries out two tests that are the same in every way except for one.
What is a controlled experiment?
