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 are still living
What is extant?
200
Mountain pine beetle infestations have devastated lodgepole pine forests across Western North America; forests with a variety of tree species, however, tend to survive. This exemplifies how an ecosystem's _________ ___________ can be used to measure its overall health.
What is diversity index?
200
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 the cause of the mass extinction event we are currently undergoing
What is human activity?
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
He published "The Origin of Species", the document upon which all of modern-day science is based.
Who is Charles Darwin?
300

Organisms that no longer exist in a particular region are referred to as

Extirpated Species 

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
This is the form of cell division that is responsible for growth, maintenance and repair.
What is mitosis?
400
This generates changes much faster than natural selection
What is artificial selection?
400
Zoos implement these to help preserve the diversity of their animals
What are breeding programs?
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

A rabbit with a phenotype of black fur an genotype of Heterozygous dominant is bred with another rabbit with white fur phenotype and genotype homozygous recessive. Statistically, what are the chances each off spring would have white fur? 

Punnett Square should should 1 Black fur (25%) and 3 White fur (75%) - but that is for EACH individual offspring not for the entire litter.

Give 3 of 4 points that make up Natural Selection Theory

1. All organisms produce more offspring than can possibly survive.

2. There is incredible variation within each species.

3. Some of these variations increase the chances of an organism surviving to reproduce.

4. Over time, variations that are passed on lead to changes in the genetic characteristics of a species.
