A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?
behavioral isolation
temporal isolation
gametic isolation
geographic isolation
Which of the following is NOT true in the formation of a new species?
A mutation causes a population to breed with a different species.
A population needs to become reproductively isolated.
Reproductive isolation can occur by the formation of a mountain range.
An isolated population has adapted to new ecological niches eventually result in the inability to reproduce with the original population.
Albert’s squirrel and the Kaibab squirrel are distinct subspecies that live on opposite sides of the Grand Canyon. They were once one species, but now differ significantly, including fur coloring. This is an example of:
Geographic isolation
Behavioral isolation
Temporal isolation
Island Isolation
The term "endemic" means
It's like an epidemic, a disease that spreads.
It's how populations spread to new areas.
related organisms that interbreed and produce fertile offspring.
A species found only in one specific area.
Mass extinction is
when many species die over a short period of time.
when one species dies over a short period of time.
when many species die over a very long period of time.
a made up idea.
Large populations with high genetic diversity are
more likely to go extinct
more likely to be invasive
less likely to go extinct
less likely to be invasive
In the last 2 centuries, extinction rates have increased along with
an increase in human population
a decrease in human population
an increase in biodiversity
a decrease in biodiversity
Select TWO responses for the following question!
Biodiversity hotspots usually have two environmental RED FLAGS that scientists use to identify them. Which of the following criteria would scientists use to identify a biodiversity hotspot? (SELECT TWO!!)
high number of endemic species
threatened by humans
abundance of water
low number of endemic species
excessive amounts of vegetation
1. The process of choosing parent organisms for desired characteristics is called
natural selection
Artificial selection
random selection
genetic manipulation
What is an example of artificial selection?
Letting dogs choose their own mate
Letting plants pollinate on their own
Crossing a labrador and a poodle to create a labradoodle
1. Artificial selection has been a big factor in the evolution of:
Dogs
Panda bears
Snakes
Jellyfish
Which statement is true comparing natural selection and artificial selection?
In natural selection, traits benefit humans and in artificial selection, the traits benefit the species
In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
In natural and artificial selection, the process takes hundreds of years to occur
In natural and artificial selection, nature determines what traits will be passed down to offspring.
Artificial selection is also known as
natural selection
selective hearing
genetic manipulation
selective breeding
Technology that enables scientists to make new sequences of DNA and to use such genetic information to design and create new cells, tissues, organisms, and devices, and to redesign existing natural biological systems.
