Who is the author of 'On the origin of Species'
Charles Darwin
This species is characterized by having only a few offspring but investing high amounts of parental care
K- Selected Species
Define Keystone Species
A keystone species is a species that has a disproportionately large impact on the environment relative to its abundance
What process results in the production of four diploid cells?
Meiosis
explain how temporal isolation can lead to speciation
teacher answer

Do Keep Pond Clean Or Froggy Gets Sick
Domain Kingdom Phylum Class Order Family Genus Species
Define carrying capacity
The maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available
What is the purpose of PCR
To amplify specific DNA strands
Proboscis length and length of flower both elongating together is an example of
co evolution
"Certain species are dependent upon one another and so may be classified or grouped together, as conservation strategies must take management of both of them into account"
Identify the species interaction being described.
Symbiosis
Explain how carrying capacity is limited by food availability
There may not be enough food for the whole population, causing some organisms to die off, therefore changing the carrying capacity of the population.
What is the role of Helicase in DNA replication
To unzip the DNA strand by breaking hydrogen bonds
example of convergent evolution
Unrelated organisms evolve similar adaptations in response to environment
What 2 measurements is spechts classification based on? How do you differentiate between a rainforest and a desert?
Ground/canopy cover and height of the tallest stratum
Explain primary and secondary succession
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance

Explain the term Trisomy 21
