Variation
Competing for Resources
Reproduce
DNA
Humans
100
An example of this type of variation is weight in humans.
What is continuous variation?
100
This type of competition involves one organism benefiting while the other is harmed.
What is parasitism?
100
The type of reproduction that occurs when only one parent supplies the genetic information.
What is asexual reproduction?
100
Two of the four nitrogen bases in the DNA molecule.
What are adenine, thymine, cytosine and guanine?
100
These are being cut down at a rate of 1% per year.
What are rainforests?
200
When one species of organism evolves into a similar, yet separate species.
What is speciation?
200
Where an organism lives and what it does.
What is a niche?
200
This is the type of reproduction in which one celled organisms reproduce asexually by duplicating their contents and then dividing.
What is binary fission?
200
DNA is organized into these, which are visible through a light microscope during cell division.
What are chromosomes?
200
This type of species in an area can be used to measure the human impact on the environment.
What is a bioindicator species?
300
He went to the Galapagos Islands on HMS Beagle and looked at the different species of finches on the islands.
Who is Charles Darwin?
300
This is the type of niche that we are most likely to find in Canada.
What is a broad niche?
300
This is a primitive form of sexual reproduction used by some bacteria.
What is bacterial conjugation?
300
This is the shape of the DNA molecule.
What is a double helix?
300
There are four points in this person's Theory of Natural Selection.
Who is Charles Darwin?
400
This is used by biologists to measure the biological diversity of an area.
What is the diversity index?
400
This is what we call an organism that has a narrow niche.
What is a specialist?
400
An advantage of this type of fertilization is that the egg doesn't dry out and is protected from the environment.
What is internal fertilization?
400
The type of trait which, if present, will show up in offspring. An example is brown eyes.
What is a dominant trait?
400
One of the extinct species which was talked about in class which became extinct due to hunting.
What are the wooly mammoth, passenger pigeon and Tasmanian wolf?
500
An example of this type of adaptation is the shape of the pitcher plant.
What is a structural adaptation?
500
In this type of competition, both organisms benefit from the relationship.
What is mutualism?
500
This type of cell division takes place in reproductive cells and produces four daughter cells from two cell divisions.
What is meiosis?
500
When humans move DNA from one cell to another in hopes of breeding for favourable characteristics.
What is genetic engineering?
500
These are established to gather and store seeds from plants that are threatened to extinction.
What are seed banks?
