Dichotomous Key
This is a tool used to identify species based on their characteristics.
What is a dichotomous key?
Adaptations are anything that helps an organism do this in its environment.
What is survive?
This naturalist developed the theory of evolution through natural selection.
Who is Charles Darwin?
This process involves humans deliberately breeding for desired traits in offspring.
What is selective breeding?
Leaves are an example of this level of organization.
What is organ?
This is the purpose of a dichotomous key.
What is to identify?
Adaptations such as a bulb-like root of a plant, gills of a shark and webbed feet of a duck are examples of this type of adaptation.
What is structural?
These type of traits are most likely to be passed on to offspring in the process of natural selection.
What are the most favorable or adaptable traits?
This species is one of the most selectively breed organisms and as a result has hundreds of breeds.
What is the dog?
An orange tree is an example of this level of organization.
What is organism?
One must always start from this number when using a dichotomous key.
What is from number 1?
The way an organism acts or behaves is known as this type of adaptation.
What is behavioral?
This theory is thought to be caused mostly by natural selection and is why species have changed slowly over time.
What is the theory of evolution?
This is an advantage of selective breeding.
What is humans get desired traits in offspring of a species?
Plant root tips have a layer of cells making them an example of this level of organization.
What is tissue?
There are this many choices at each number on a dichotomous key.
What is two choices?
This type of structural adaptation gives the organism the ability to blend into its environment.
What is camouflage?
This expression is used when talking about natural selection and means that the organisms that can survive have the most favorable or adaptable traits.
What is "survival of the fittest?"
What is health issues or no variation in genes?
This body system contains glands that secrete hormones which help regulate body processes.
What is the endocrine system?
What are characteristics?
This behavioral adaptation involves getting away or moving from one place to another during harsh winters.
What is migration?
These are the islands that Charles Darwin began is development of evolution through natural selection.
What are the Galapagos Islands?
This is another term for selective breeding.
What is artificial selection?
This the density of a substance with a mass of 5g and a volume of 2cm3.
What is 2.5g/cm3?
