EOC Biology Review Assignment

Front

What is the geological principle that states the oldest rock layers are at the bottom?

Back

The Law of Superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top.

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, primarily converting carbon dioxide and water into glucose and oxygen.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes, such as mitochondria for energy production and chloroplasts for photosynthesis.

Front

What is species divergence?

Back

Species divergence is the process by which two or more species evolve from a common ancestor, leading to genetic differences over time.

Front

What is the definition of an organ system?

Back

An organ system is a group of organs that work together to perform complex functions for the body, such as the circulatory system or the digestive system.

Front

What is cancer in biological terms?

Back

Cancer is a disease characterized by uncontrolled cell division due to mutations in genes that regulate the cell cycle.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of a once-living organism, often found in sedimentary rock.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What is the significance of genetic differences in species?

Back

Genetic differences among species can indicate evolutionary relationships and adaptations to different environments.

Front

What is a tissue in biological terms?

Back

A tissue is a group of cells that work together to perform a specific function, such as muscle tissue or nervous tissue.
