What is a behavior or physical characteristic that allows an organism to survive and reproduce in its environment?
Adaptation
100
What needs to occur in order for Natural Selection to happen in a population?
Environmental Change/a change in the environment
100
Why are the early in development embryos similar between chickens and humans?
Because they share a common ancestor.
100
Define population
A collection of individuals belonging to the same species, in the same region, interbreeding with one another

What do bees collect and use to make honey?
Pollen
200
What is a defense mechanism or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings.
Embryo
200
Who defined the idea of evolution through natural selection?
Charles Darwin
200
Draw an early stage embryo.
200
How do environmental interactions affect the survival and reproduction of a population?
The ones who are best fit for the environment after a change are the survivors. When they survive, they have a higher chance of reproducing.
200
What is the largest organ in the human body?
The skin
300
What is a trait that helps an organism to outperform others in its population; it is a major driving force behind evolutionary change
Competitive Advantage
300
What caused the variety of beak sizes of the Finches in the Galapagos Islands?
The environment becoming drier/less variety of seed sizes.
300
When do embryos get the traits that align with their species?
Right before hatching or birth

A population of peppered moths live outside of London. The lighter colored peppered moths blend in well with light colored birch trees. The darker colored peppered moths blend in well with trees that have been covered with soot due to pollution. Humans have begun to decrease the amount of pollution they are putting into the air.
Which variation will have a higher probability of survival when the pollution decreases?
The light-colored peppered moth.
300
What is the name of the most recent supercontinent?
Pangea
400
What is a defense mechanism or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings.
Camouflage
400
Where do we see natural selection within a population?
In the offspring/ the offspring changing or looking like the surviving population.
400
What physical similarities and differences would you expect to see between a newly hatched salamander and a salamander embryo midway through its development (60-75 days after fertilization)?
A. They would have just as many physical structures in common as embryos as they do when they hatch.
B. They would have more physical structures in common as embryos than when they hatch.
C. They would have fewer physical structures in common as embryos than when they hatch.
C
400
In this population of chipmunks, there is a lot of variation in coat color. The colors range from light to dark.
After a mudslide, the landscape became full sandy soil, making the ground lighter in color.
How will the coloring of the chipmunks change over time, due to natural selection?
The lighter colored chipmunk population will increase.

What is Ms. Lindsey's favorite animal?
500
What is one species that is the ancestor of two or more species later in time?
Common Ancestor

Define Natural Selection.
The process by which organisms better adapted to their environment tend to survive and reproduce more successfully, thus passing on their genes to the next generation.
500
Why do all the early embryos look the same for invertebrates (animals with a spine).
They share a common ancestor.
500
There are two populations of elephants. Population A has a lot of genetic variety in each individual's ability to survive with little water. Population B has a very little genetic variety in each individual's ability to survive with little water.
Which population is more likely to survive a drought>
Population A

What number am I thinking of from 1-100?
