What happens to prey numbers when predator numbers decrease?

Back

Prey numbers increase because fewer of them are being consumed.

Front

What is the Founder Effect?

Back

The Founder Effect occurs when a small group of individuals migrates from a larger population and establishes a new population, leading to reduced genetic diversity.

Front

Which two body systems are responsible for gas exchange?

Back

The circulatory and respiratory systems are primarily responsible for gas exchange between the body and the environment.

Front

What is Gene Flow?

Back

Gene Flow is the transfer of genetic material between populations through migration and interbreeding.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

Define adaptation in biological terms.

Back

Adaptation is a process by which a species becomes better suited to its environment through evolutionary changes.

Front

What is the role of the circulatory system?

Back

The circulatory system transports nutrients, gases, hormones, and waste products throughout the body.

Front

What is the primary function of the respiratory system?

Back

The primary function of the respiratory system is to facilitate gas exchange, specifically oxygen intake and carbon dioxide removal.

Front

Explain the concept of a gene pool.

Back

A gene pool is the total collection of genes and their variants in a population.

Front

What is the difference between migration and gene flow?

Back

Migration refers to the movement of individuals from one location to another, while gene flow specifically refers to the exchange of genetic material between populations.
