Evolution Test Review

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. It is a key mechanism of evolution.

Front

What is reproductive isolation?

Back

Reproductive isolation is a condition that prevents different species from interbreeding, leading to the formation of new species.

Front

What is genetic mutation?

Back

Genetic mutation is a change in the DNA sequence of an organism's genome, which can lead to variations in traits and may contribute to evolution.

Front

What is the significance of photosynthetic organisms in the atmosphere?

Back

Photosynthetic organisms, such as plants and algae, produce oxygen as a byproduct of photosynthesis, significantly increasing the oxygen levels in the atmosphere.

Front

What is common ancestry?

Back

Common ancestry refers to the idea that different species share a common ancestor from which they have evolved over time.

Front

What is divergent evolution?

Back

Divergent evolution is the process by which two or more related species become more dissimilar over time, often due to different environmental pressures.

Front

What is the role of mutations in evolution?

Back

Mutations introduce genetic variation into a population, which can lead to new traits that may be beneficial for survival and reproduction.

Front

What is the relationship between species and their environment?

Back

Species adapt to their environment through natural selection, which shapes their physical and behavioral traits over generations.

Front

What is the difference between asexual and sexual reproduction?

Back

Asexual reproduction involves a single organism producing offspring identical to itself, while sexual reproduction involves the combination of genetic material from two parents.

Front

What is the impact of antibiotic resistance?

Back

Antibiotic resistance occurs when bacteria evolve to survive exposure to antibiotics, making infections harder to treat.
