The phrase "Survival of the Fittest" would best describe
Natural Selection
Artificial Selection
Selective Breeding
None of the Above
Which is not true about natural selection?
There must be diversity in the population.
It is driven by natural processes like predators or weather conditions.
Humans are involved and can select the most desirable organisms.
Predators, geological activity, and weather can all have an impact on organisms.
What is one problem with artificial selection?
It takes thousands of years.
It removes diversity and bad traits can surface.
It promotes biodiversity of the species.
It can only happen once a year.
Children that inherit traits from their parents are called
Offspring
Babies
Species
Biodiversity
Humans play a role in artificial selection.
True
False
_____________ is a trait or behavior that happens over time that helps an organism survive and function better in their environment.

Artificial Selection relies on diversity in population, so the fittest members will survive.
True

True
False
The term "survival of the fittest" refers to

In a situation where shrubs and lower leaves on trees disappeared and both long neck and short neck giraffes depended on this for a food resource - would the short neck giraffes grow longer necks to adapt?
Yes, that's the only way they can survive.
No, more than likely they will die out because organisms can't change their traits.
Yes, the short neck giraffe would be able to stretch to reach higher places and over time pass that on to it's offspring.
No, the short neck giraffe would just have the long neck giraffe get leaves from higher places for them.
Which of the following is true about Natural Selection?
It takes place over a relatively short period of time.
Humans have a decision in the outcome of the offspring.
The process happens due to environmental activity.
Organisms are able to quickly adapt to the changes in their environment.
Which of the following is true about Selective Breeding?
It can also be called Artificial Selection
It can have negative impacts on the species and biodiversity.
It takes place over a relatively short period of time.
All of the above are true.
