Scientists hypothesize about the origin of life.

It began in deep-sea hydrothermal vents.

It was created by extraterrestrial beings.

It started from a single-celled organism.

It originated from a chemical reaction in the ocean.

Mitochondria serve a specific purpose in eukaryotic organisms. What is this purpose, and what evidence supports the hypothesis that they were once free-living cells?

Energy production; presence of their own DNA and double membrane

Protein synthesis; lack of ribosomes

Photosynthesis; presence of chlorophyll

Cell division; ability to replicate independently

What do fossils reveal about ancient life?

Fossils reveal the evolution and extinction of ancient life.

Fossils reveal the diet and behavior of ancient life.

Fossils reveal the climate and environment of ancient life.

Fossils reveal the size and shape of ancient life.

Climate change has affected the history of life by:

causing mass extinctions and altering habitats

stabilizing global temperatures

What does 'extinct' mean?

Being in danger of disappearing.

What is 'background extinction'?

Extinction caused by the slow and steady process of natural selection.

Extinction caused by catastrophic events.

Extinction due to human activities.

Extinction of species in a specific habitat.

What is 'mass extinction'?

An event during which many species become extinct during a relatively short period of time.

A process of gradual adaptation of species to their environment.

A phenomenon where a single species dominates an ecosystem.

A natural event that leads to the formation of new species.

What is the definition of convergent evolution?

D) Evolution of similar characteristics in unrelated organisms

A) Evolution of a species by gradual accumulation of small genetic changes over long periods of time

B) Evolution in which long, stable periods are interrupted by brief periods of more rapid change

C) Process by which a single species or a small group of species evolves into several different forms

What is the definition of coevolution?

D) Process by which two species evolve in response to changes in each other over time

A) Evolution of a species by gradual accumulation of small genetic changes over long periods of time

B) Evolution in which long, stable periods are interrupted by brief periods of more rapid change

C) Process by which a single species or a small group of species evolves into several different forms

Have changes in climate occurred in the past? Give examples.

Yes, changes in climate have occurred in the past, such as the Ice Age.

No, climate has remained constant throughout history.

Climate changes are only a recent phenomenon due to human activity.

Climate changes have occurred only in the last century.

A mass extinction is defined by what criteria, and what are the immediate effects on biodiversity?

A significant and rapid decrease in biodiversity, leading to the loss of many species.

A gradual change in climate affecting only a few species.

An increase in biodiversity due to new species emerging.

A slow and steady evolution of species over millions of years.
