Natural selection means
those with any traits will survive and reproduce
those with changing traits will survive and reproduce
those with traits best suited for the environment will survive and reproduce
the strongest will survive and reproduce
Some insects on an island survive while other insects do not survive. The insect populations that did survive
had an advantageous trait
choose a trait that was suitable for the environment
moved away
were not strong enough
The picture of the horse bone fossils shows that
horses changed very quickly into what we see today
horses are smaller today than they were a long time ago
the fossils did not have any similarities
the horse changed over long periods of time
What provides evidence of organisms that lived in the past?
soil
blood
fossils
rocks
What caused the finch beaks to look different on the Galapagos Islands?
The birds were different species.
Each beak was adapted to finding water.
Each beak was adapted to a type of food.
The birds competed with each other for food.
Think about animals that live in water. Which adaptation would best suit an animal in aquatic conditions?
sharp claws for catching prey
curling into a ball when threatened
oily fur to keep dry even in water
hunting at night
What can tell how closely two organisms are related?
MRI
CAT
DNA
DOG
A fish had a mutation which caused a change in coloration. After many years, most of the new fish population had this mutation. What most likely caused this?
Several fish got the mutation at the same time.
The fish with the mutation was better suited for the environment.
The fish choose the mutation to have an advantage.
The mutation was contagious.
According to natural selection, in a population of frogs
the strongest frogs will survive and reproduce
the frogs that are best camouflaged will survive and reproduce
the frog with traits best suited to the environment will survive and reproduce
the frogs with the best reflexes will survive and reproduce

What is the significance of the similar number and arrangement of bones in a human arm and a bat wing?
The organisms that live the longest are the fittest.

Sharks and turtles have similarities in their DNA. What does this suggest?
They have a common ancestor.
They eat the same type of food.
They live in the same ecosystem.
They are becoming more alike.
Fish, tortoises, and chickens have similar early development. What can we conclude?
They live in the same ecosystem.
They will look similar as adults.
They share a common ancestor.
A species lives in a particular environment. What is TRUE about the environment that the species lives in and about how the species will look over thousands of years?
The environment will stay the same, and the traits of the species will stay the same.
There will be changes to the environment, but the traits of the species will stay the same.
There will be changes to the environment that could lead to changes in the traits of the species.
There will be changes to the environment, and the traits of the species will change, but the changes in the environment could never lead to changes in the traits of species.
