What’s the definition of natural selection
The process of when animals adapt to their environment but become extinct
The processs where they don’t adapt to their environment but reproduce more species
The process which and individual adapt to their environment and produce more of the same species
Evolution
whats the definition of variation
an individual that has a lot of the same characteristics
Any difference between individuals
A group of similar offspring
Natural selection
What’s the definition of evolution
The change in species over time
No change in species over time
Adaptation to their environment
Not adapting to their environment
What’s the definition of homologous structures
Body structures the are different in related species
Body structures that are structurally similar in related species
Body structures that are rare
Body structures that could be endangered
What’s the definition of adaptation
A trait that hurts the organism and fails to reproduce
A trait that helps the organism but fails to reproduce
A trait that hurts the organism Andy reproduces
A trait that helps the organism and to reproduce
Mutations (why helpful)
Change in the chromosomes
Mutations harm the organism
Mutations is the process in which organisms can adapt better
Mutations essential to evolution they cause changes in aspects of life. Without mutations evolution wouldn’t be possible
Species
A group of different organisms that mate with each other’s to produce offspring
A group of the same organisms that don’t mate with each other
A group of organisms that are the same and mate with each other to make fertile offspring
A group of organisms that are the same and mate with each other but don’t make fertile offspring
How are adaptations related to Natural Selection
Because adaptations is how they adapt to they get a trait that helps them survive and Natural selection relates to that because when they reproduce they are better adapted to their environment.
Because adaptations and natural selection are technically the same thing because they both help each other reproduce
They sound a like
Natural selection and adaptations is how the animals and organisms help get better android more comfortable to their environment
Why does a species NEED VARIATIONS in order for natural selection and evolution to occur
More are born then survive (overproduction)
Organisms vary even within their species
Differences between reproduction and survival are due to variation
all of the individuals would have the same chance of surviving and reproducing
How do organisms get adaptations
Natural selection
Variations
Evolution
All of the above
Which organisms are selected during natural selection? WHY??????
The ones that are more likely to survive. Because they produce less of the successful organisms
The ones that are more likely to survive. Because they produce more of the successful organisms
Because of evolution
they are selected because they are more physical.
How could change in the environment lead to evolution.
It would be good because it changes how they survive
It's bad because now they have to spend a lot of time with Natural selection Andy getting used to their new environment while trying to survive
It's good because me they can use two ways of living and surviving
It's bad because now mutations form
How closely related are homologous bones
Similar within different organsism
Similar within related organisms
Different within similar organsims
all of the above

1 parent
Identical offspring
Fish Mammals and birds
Asexual reproduction
