30 by 30 Initiative
What is the 30x30 Initiative?
Protecting 30% of land and oceans by 2030 to conserve nature
What is natural selection?
The process where organisms with helpful traits are more likely to survive and reproduce.
What is genetic drift?
A random change in the genetic makeup of a population over time.
What is evolution?
The change in species over time.
Why was the 30x30 Initiative created?
To reduce biodiversity loss and protect ecosystems
A population of rabbits lives in a snowy area. White rabbits are harder for predators to see than brown rabbits. What will likely happen over time?
White rabbits will become more common because they survive and reproduce more.
In which type of population is genetic drift strongest?
Small populations.
What is an adaptation?
A trait that helps an organism survive and reproduce.
How does the 30x30 Initiative help people?
It supports clean water, food supplies, and climate stability.
Why is variation important in natural selection?
It gives some organisms a survival advantage.
A storm randomly kills half the birds on an island. The surviving birds have different allele frequencies than before. What process occurred?
Genetic drift (bottleneck effect).
How can a rabbit population change over time if darker fur helps them survive?
Through natural selection, darker-furred rabbits survive and reproduce more, making darker fur more common in future generations.
What is a challenge of the 30x30 Initiative?
Balancing conservation with economic and land-use needs.
Some bacteria are resistant to an antibiotic while others are not. After treatment, what happens to the bacterial population?
Resistant bacteria survive and multiply, making resistance more common.
Genetic drift causes allele frequencies to change due to ______ events.
random.
Evolution is the process by which species change over ________.
Time.
How can people support the 30x30 Initiative?
By supporting conservation efforts and practicing environmental stewardship.
How does natural selection cause evolution?
Helpful traits become more common over time.
A few rabbits move to a new island and start a population with only some of the original alleles. What process occurred?
Genetic drift (founder effect).
Organisms that are better suited to their environment are more likely to ________ and reproduce.
survive.
