What is natural selection?
When reproduction occurs and mutations happen.
When a offspring has the traits from its parents.
When an organism is able to camoflauge in its environment.
the process whereby organisms that are better adapted to their environment tend to survive and reproduce more offspring.
In a cold environment what would be some adaptive traits? Sellect all that apply.
thick blubber
thick fur
thin fur
strong muscles
What is a trait?
a color
the quality or characteristic of an organism
the DNA of an organism
when mutatuons cause extra limbs.
Which of these are possible traits of a rattle snake?
Select all that apply
venom
rattle
hair
legs
scales
Why do offspring share traits from both parents?
offspring choose the traits they want
offspring get 75 percent of the traits from their father
offspring get 50 percent of each parents DNA
What must organisms do when an environment changes?
Adapt
Camoflauge
become common
fight
What needs to be true for adaptation to occur?
A trait exists in a population
Organism's ability to survive and reproduce are increased
Trait is heritable

Why/how do population change over time?
The environment changes
There is a heritable trait which doesn't help survival
Natural selection causes a trait to become more common in the population
