Unit 8 - Unit 9 Practice Test (Biology Evolution...)

What is "Evolution"

• The process that humans change over time

• The process that animals change over time

• The process that change over time

• None of these answers

Answer explanation

Humans, Animals, ad other species share unique evolution.

What are "adaptions"?

What is the best definition?

• Helps the organism to stay the same.

• Change in behavior of the organism

• Adjustments in an organism's physiology

• Traits that help the organism survive and reproduce

(True or False) The three distinctive patterns for biological diversity are species vary globally, locally, and over time.

• True

• False

What is Natural Selection?

• Based on survival, environment, and Phenotype. As going further, the environment changes and means that different things become beneficial.

• Common traits aren't beneficial

Select 4 parts that can modify or are part of Natural Selection.

• Different Variations

• Organisms Overproduction

• Adapting to the the environment (Adaptations)

• Descent with Modifications (over time change in the environment)

• Selected Fitness (ability to survive more than others)

What are Variations?

• Variations in populations are basic for natural selection

• Differences between organism to organism

• Genetic mutations

• Organisms that can outwit the other organism

What is overproduction?

• Over-fishing or over hunting the same organisms

• Organisms cannot stop producing offspring

• Over Competition

What is "Adaptations"?

• Organisms surviving at higher rates

• Suited for survival based on different organisms.

• Able to produce offspring.

Answer explanation

Adaptation - some adaptations allow organisms to survive at higher rates and individuals are “naturally selected” to survive and produce offspring 

What is Fitness?

• Exercising and getting stronger

• ability to produce offspring and survive (relative to other members of a population)

• ability to produce offspring and survive (based on the Hardy-Wilberg Theory)

• Eating healthy and balanced meals

What is Artificial Selection?

• Process by which humans change a species by breeding it for certain traits

• Based on Phenotypes, as environment changes, different traits will become beneficial. 

• Based on Genotypes, as environment changes, different traits will become beneficial. 

• Process by which humans and animals change a species by breeding it for certain traits.
