Inheritance
Natural Selection
The Sixth Extinction
100
These increase an organism's probability of surviving in a particular environment
What are adaptations?
100
In this general form of reproduction, a parent donates 100% of its genetic material to offspring
What is asexual reproduction?
100
These are sections of DNA that encode specific traits
What are genes?
100
The term used to describe the idea that individuals who are best suited to their environment will survive.
What is survival of the fittest?
100

This is the term used to refer to species that is no longer present in a specific area

What is extirpated

200

between brazil, russia, and southern Australia, which would have the greatest biodiversity?

brazil

This form of asexual reproduction occurs when a single-celled organism duplicates its DNA and splits into two genetically identical cells.
What is binary fission?
200
These types of variations are often the result of a single gene
What are discrete variations?
200
The formation of new species through natural selection
What is evolution?
200

This is largely the cause of all five mass extinctions and is a natural cause of the extinction of species

What are natural disasters & climate change?

300
Organisms with this type of niche tend to thrive in one particular environment
What is a narrow niche?
300
This is one of the major drawbacks of sexual reproduction.
What is the inability to reproduce quickly?
300
These types of traits will only be expressed if two of the corresponding alleles are present in an organisms genetic code
What are recessive traits?
300

variation amongst us humans, how we have different eye color, different hair color is an example of this

variation within or among species

300

is a cause of extinction when species are most sensitive environmental changes because they have a limited selection of habitat and food sources

what is overspecialization

400
This term is used to describe what an organism eats, its range and habits, and the impact it has on other species.
What is niche?
400
This is the name used to describe the cell that forms immediately after a sperm fertilizes an egg
What is a zygote?
400

I am a animal.  I have 33 pairs of chromosomes.  how many chromosomes would my gametes cells have?

what is 33

400

This generates changes much faster than natural selection and is done by humans, not nature

What is artificial selection?

400
This is the cause of the mass extinction event we are currently undergoing
What is human activity?
500
This form of symbiosis is utilized by remora fish and sharks, where one organism receives some sort of benefit from the relationship and the other receives neither benefit nor harm.
What is commensalism?
500
Lack of diversity is a drawback of this type of reproduction
What is asexual reproduction?
500
This is the form of cell division that is responsible for growth, maintenance and repair.
What is mitosis?
500
Natural selection is driven by this
What is environmental change?
500

Zoos would be a example of this conservation method that are meant to help preserve the diversity of their animals

What is ex situ conservation
