Bears sleeping all winter
What is hibernation?
100
The three types of isolations that can lead to speciation.
What is Geographic, Behavioral, and Reproductive?
Bonus: Temporal- if the seasons in which the two groups mate are different.
100
When individuals have an advantageous trait that gives them an advantage in the fight for resources and survival.
What is competition
100
The 4 kinds of evidence for evolution
What is anatomy, embryology, biochemistry, and fossils?
100
An inherited trait that increases an organism's chances of survival
What is an Adaptation?
200
Adaptations that affect how an organism acts
What is Behavioral adaptations?
200
A company has received the rights and permission to build a factory in a current forested area. This area is the only location of apple snails, which is the only food source of the everglades snail kite (a type of bird). This company completes demolition of the forest and begins production within 2 years.
What is extinction?
200
Producing more offspring than will survive
What is overproduction?
200
The type of anatomy that has similar structure but may have different functions.
What are homologous structures?
200
The ability to survive and reproduce
What is fitness?
300
Adaptations that affect the physical features of an organism
What are Structural/physical adaptations?
300
A population of lizards live in an area that has started to be much hotter and drier over the last 15 years. Most of the lizards eat insects as a primary diet, but a few of the lizards will also eat plants. As the area has started to get hotter and drier, there have been fewer and fewer insects since they avoid the heat.
What is natural selection?
300
When one trait is better at helping an individual survive in an environment than another trait then nature will _______ the __________ trait.
What is nature will select the advantageous trait?
300
The thing that biochemistry (DNA/RNA) looks for in sequencing in related species.
What are differences or similarities?
300
The purposeful choosing of traits by humans
What is Artificial Selection?
400
Being able to blend in to your environment
What is camouflage?
400
There is a large population of birds in a rainforest. Most of the birds eat insects and many will also eat seeds. As the population begins to experience competition for the insects as food, a small group begins to mainly eat the seeds. The seed eaters are in a different section of the trees than the ones still mainly eating insects. They become more isolated over several years.
What is speciation?
400
A unique combination of inherited traits
What is Variation?
400
The type of evidence for evolution being shown. (This is an armadillo by the way)
What are fossils?
400
A random change in a gene that can either benefit or harm an individual
What is a mutation?
500
Adaptation bats and dolphins have to help them hear and locate each other.
What is echolocation?
500
A prairie area covered in thick grasses is home to a population of mice. The mice come in a variety of tan and brown shades. Each of the color variations seems to be able to find mates and food without difficulty. Also, the predators like hawks don't seem to notice one of variation over the other.
What is NOT natural selection?
500
Natural selection acts on this rather than genetics
What is the phenotype?
500
The type of anatomy that has different structures but the same function.
What are analogous structures?
500
Traits that become more common in a population
What are advantageous traits?
