GA biology EOC practice semester 1

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the cell structures where protein synthesis occurs, translating messenger RNA (mRNA) into polypeptide chains.

Front

What distinguishes plant cells from animal cells?

Back

Plant cells contain chloroplasts for photosynthesis and a cell wall for structure, while animal cells do not.

Front

What role do enzymes play in metabolic reactions?

Back

Enzymes speed up metabolic reactions, allowing organisms to efficiently convert food into energy.

Front

Why is it important to preserve ecosystems like those in state parks?

Back

Preserving ecosystems maintains biodiversity and stability, preventing damage caused by human activities.

Front

What impact did the reintroduction of gray wolves have on the Yellowstone ecosystem?

Back

The reintroduction of gray wolves decreased the elk population, allowing vegetation like willows and aspens to thrive, which in turn supported other species.

Front

Define biodiversity.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species.

Front

What is a limiting factor in an ecosystem?

Back

A limiting factor is a resource or condition that limits the growth, abundance, or distribution of an organism or a population.

Front

Explain the concept of carrying capacity.

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

How do human activities impact ecosystems?

Back

Human activities can disrupt ecosystems by removing species, altering habitats, and introducing pollutants, leading to loss of biodiversity.
