Biology Semester 1 Review

Front

What temperature range promotes the highest population growth rate in pea weevils?

Back

Cold springs with temperatures from 11°C to 16°C promote the highest population growth rate in pea weevils.

Front

Which types of cells contain genetic material in a nucleus?

Back

Both plant and animal cells have genetic material contained in a nucleus.

Front

How can humans promote the survival of organisms in an ecosystem?

Back

Humans can promote survival by learning about the interactions of populations.

Front

What invention from the 17th century contributed to the development of modern cell theory?

Back

The light microscope allowed for the development of modern cell theory.

Front

What is the benthic zone in aquatic ecosystems?

Back

The benthic zone is the lowest ecological zone in a body of water, where there are no producers that rely on photosynthesis.

Front

What is the role of autotrophs in an ecosystem?

Back

Autotrophs are organisms that produce their own food, typically through photosynthesis, and are essential for energy flow in ecosystems.

Front

What is cell theory?

Back

Cell theory states that all living organisms are composed of cells, and that cells are the basic unit of life.

Front

What are the main differences between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity enhances ecosystem productivity and stability, allowing for a greater variety of species and interactions.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
