What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome, which can lead to changes in traits or functions.

Front

What causes a mutation?

Back

A mutation can be caused by chemicals that change DNA, radiation, or errors during DNA replication.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that have similar functions but evolved independently, not from a common ancestor.

Front

What is the significance of genetic diversity in populations?

Back

Genetic diversity increases a population's ability to adapt to changing environments and resist diseases.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, maintaining balance in the ecosystem.

Front

What is the difference between asexual and sexual reproduction?

Back

Asexual reproduction involves a single parent producing offspring identical to itself, while sexual reproduction involves two parents combining genetic material.

Front

What is the impact of disease on predator populations?

Back

A disease that reduces predator populations can lead to an increase in prey populations due to decreased predation.

Front

What is the relationship between structure and function in biology?

Back

In biology, the structure of an organism or its parts is closely related to its function, meaning that the form of a biological entity is adapted to its role.
