Vocabulary
A group of individuals of the same species living in a specific area, interacting and reproducing.
A. Mutation
B. Variation
C. Population
D. Evolution
C. Population
A population of mice lives in a forest where a new virus is spreading. Some mice have a genetic mutation that makes them resistant to the virus, allowing them to survive and reproduce. Over time, more mice in the population carry this mutation.
Mutation Type:_______________________________
A. Positive mutation
B. Negative mutation
C. Neutral mutation
A. Positive mutation
What is a process where organisms with traits that help them survive live longer and reproduce, passing those traits to the next generation.
A. Mutation
B. Gene drift
C. Natural selection
D. Variation
C. Natural selection
The process by which new species arise from existing ones.
Speciation
A change in an organism's DNA sequence.
A. Mutation
B. Variation
C. Population
D. Evolution
A. Mutation
A mutation causes some deer in a population to lack pigment in their fur, making them completely white (albino). These deer stand out more in their environment, but the mutation does not directly affect their health or survival.
Mutation Type:_______________________________
A. Positive mutation
B. Negative mutation
C. Neutral mutation
True or false: Over time, populations change based on which traits are most beneficial
True
What is an important cause of speciation?
A. Isolation
B. Heat
C. Special Traits
D. None of the above
A. Isolation
Differences in traits among individuals within a population.
A. Mutation
B. Variation
C. Population
D. Evolution
B. Variation
Some cats are born with a mutation that gives them extra toes (polydactyl cats). This trait does not harm the cat, nor does it provide a survival advantage.
Mutation Type:_______________________________
A. Positive mutation
B. Negative mutation
C. Neutral mutation
C. Neutral mutation
Those best adapted to their environment survive and reproduce is _____.
A. Inheritance
B. Competition
C. Variation
D. Sudden change
B. Competition
When a physical barrier (mountains, rivers, oceans) separates populations, preventing them from interbreeding is called _____.
A. Behavioral isolation
B. Geographic isolation
C. Temporal isolation
D. Gene drift
B. Geographic isolation
Physical trait shown (brown eyes, blue eyes).
A. Genotype
B. Phenotype
B. Phenotype
A mutation in some turtles causes their shells to be softer than normal. This makes them more vulnerable to predators and environmental dangers.
Mutation Type:_______________________________
A. Postive mutation
B. Negative mutation
C. Neutral mutation
B. Negative mutation
True or False: A farmer plants identical seeds that all grow the same way is an example of natural selection.
False
Differences in mating rituals or behaviors prevent individuals from interbreeding is called ______.
A. Behavioral isolation
B. Geographic isolation
C. Temporal isolation
D. Gene drift
A. Behavioral isolation
What is a well-tested and widely accepted explanation of natural phenomena based on evidence and observations.
A scientific theory
A mutation occurs in some cheetahs that allows them to run slightly faster than other cheetahs in their population. This makes them more successful at catching prey and surviving.
Mutation Type:_______________________________
A. Positive mutation
B. Negative mutation
C. Neutral mutation
A. Positive mutation
What is not one of the key principles of natural selection?
A. Variation
B. Competition
C. Survival of the fittest
D. Sudden changes
D. Sudden changes
Populations reproduce at different times or seasons, preventing genetic mixing is called ____
A. Behavioral isolation
B. Geographic isolation
C. Temporal isolation
D. Gene drift
C. Temporal isolation
