Artificial Selection can be defined as...
The selective breeding of organisms by humans for specific, desirable characteristics.
The process where individuals with certain characteristics that make them better adapted to their environment survive
The change in characteristics of a population from one generation to the next.
The differences in heredity among a population
Which answer choice provides an example of artificial selection?
A farmer collects seeds of plants that grow larger fruit, then plants more of this type of seed.
A dog breeder controls the type of dogs that mate to produce dogs with thicker fur.
A rancher breeds cattle with long horns to produce more longhorn calves.
Each answer choice is an example of artificial selection.
An adaptation can be defined as...
A random change that occurs in the genetic makeup of an organism.
The environment in which an organism lives.
A characteristic that allows a population to survive while another population does not survive.
The change in characteristics of a population from one generation to the next.
Which answer choice is an example of an adaptation?
A group of deer have thick fur that keeps them warm in the winter time.
A bird has a beak that allows it to eat a specific type of insect.
A group of peppered moths has a darker skin color that allows them to blend in with the dark smoke in the sky
Each answer choice is an example of adaptation.
Which answer choice provides a correct definition for natural selection?
A type of selective breeding where humans control how organisms mate.
The process of two species evolving in response to a long-term interaction.
The process where individuals or populations that have characteristics that make them better adapted to their environment survive.
A change in characteristics among a population from one generation to the next.
Evolution is a change in a population, not an individual
True
False
Evolution of Resistance (a.k.a. Resistance) is when...
Two species evolve in response to long-term interactions with each other.
A species develops the ability to tolerate a chemical or disease-causing agent
Humans determine how plants and animals mate to produce offspring with specific characteristics.
A species resists the process of evolution
Which answer choice is an example of resistance?
Insects eating crops are not killed by insecticide
Deer that live in a cold environment do not grow thicker fur
A honey creeper population and wildflower population develop new physical characteristics in response to one another
None of the answer choices listed
In which situation can an organism not adapt?
When it's physical surroundings change
When selective breeding occurs
When it is responding to another organism
When it's natural resources change
Which answer choice provides a correct definition for co-evolution?
The process of becoming adapted to the environment
The process in which individuals that are better adapted to their surrounding are able to survive
The process of two species evolving in response to long term interactions with one another
All of the answer choices provide a correct definition for co-evolution
An organism is resistant to a chemical if it...
Has a gene that enables it break down the chemical
Has been periodically exposed to small amounts of the chemical over time
Was not in the area when the chemical was applied
Did not eat anything with the chemical on it
Some organisms are more likely to survive because they...
Have certain physical traits
Lack certain physical traits
Have certain behaviors
Lack certain behaviors
All of the answer choice provide an explanation why some organism are more likely to survive.
For evolution to occur in a population, individuals with a trait that is "naturally selected" for must...
Live a long time
Be physically stronger than other populations
Successfully reproduce
Co-evolve
