Sea turtles can lay as many as 200+ eggs. Why does the ability of laying 200+ eggs increase the fitness of this species?
Increases the possibility that some offspring will be able to compete for food
It increases the probability that some offspring will survive long enough to reproduce.
It increases the probability that some offspring will mutate their genes
It increases the probability that some offspring will take in more carbohydrates
What are the 3 elements of natural selection (pg 58)
static environment, unlimited resources, non inherited variation
DNA, RNA, Protein
no competition, same species, less offspring
compete for resources, inherited variation, produce more offspring than can survive
A harmless fly and a bee with a stinger have similar band patterns. For the fly, the adaptation of having a similar pattern is known as mimicry. Why is this adaptation important for the fly?
to blend in with its environment
to protect the fly from predators
to blend in with other flies
for gene expression
When millipedes are threathened, they excrete a foul-tasting chemical known as cyanide. Why is this adaptation important for the millipede?
Millipedes DO NOT want to survive and reproduce
They are not able to reproduce
millipedes want to attract a mate
They are not attacked by most predators and are able to reproduce successfully
Deer get pregnant in the fall and give birth in the summer. Why is this adaptation important for their offspring?
Deer meet their mate in the fall
Ensures that offspring are born when food is most available
To ensure their offspring have inherited variation
To produce more offspring than can survive
The image above represents which mechanism of evolution?
Natural Selection
Gene Flow
Mutation
Recombination
Genetic Drift
What increases due to gene flow?
Natural Selection
Genetic Variation
Survival of the Fittest
Genetic Drift
Gene flow is the exchange of genes between two populations. Over time, what will happen to the future offspring?
The future offspring will die
The future offspring will leave
The future offspring will have greater genetic variety
The future offspring will stay the same
Which result is most likely to occur to the mice population due to predation over time?
The light colored mice will move to another rock
The number of dark colored mice population will increase
The number of dark colored mice population will decrease
There will be more light colored mice than dark colored mice
The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them-
Survive and undergo mutations in their DNA
Lower the mortality rates of the population
Produce offspring that run at average speeds
Reproduce and increase the frequency of their genes in the population
Which statement about the cottontail rabbit in this environment is best supported by the data?
Rabbit B are most fit for the environment because it produces more offspring
Rabbit A is most fit because it runs faster
Rabbit C is most fit because it has a shorter life span
All rabbits are best adapted in the environment
How has the seed dispersal method developed by these plants given them a reproductive advantage?
The method ensures that offspring will be dispersed and reduces competition for resources
The method reduces the chance that herbivores will consume the seeds
The method lengthens the life cycle of each of these plants
The method reduces the plants’ need for water and other nutrients
A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called
Natural Selection

Random mutations
Variations in a species
The differences among a species, like different bird beaks, are called -
produce more offspring than can survive
inherited variation
gravity
theories

During meiosis, a developing male pig had a change in his DNA that resulted in his coat becoming spotted.
What is the purpose of a cladogram?
To map the ancestral relationships and shared traits of different organisms.
To trace the inherited traits of a single species over time.

The diagram below represents possible genetic relationships between groups of organisms.
Which statement is a valid conclusion that can be drawn from the diagram?
Insects are more complex than mammals.
Earthworms and sea stars have a common ancestor.
Snails appeared on Earth before corals.
Sponges were the last new species to appear on Earth.
Certain species of the coral-like sea organisms called bryozoans first
appeared about 140 million years ago. They remained unchanged for the first 40
million years and then suddenly experienced rapid genetic change.
punctuated equilibrium
gradualism
rapid change in envrionment
punctuated equilibrium
gradualism
where species slowly change over long periods.

A virus killed most of the blue-footed ducks in Japan reducing the
population from 9,000 to 900. In an effort to help preserve the species, 50 blue-
footed ducks were trapped and used to start a new population in England.
Eventually the two blue-footed duck populations could no longer successfully
interbreed. This event would best be described as -
speciation
mutation
