STAAR EOC Biology Review

Front

What is cancer?

Back

Cancer is a disease characterized by uncontrolled cell division, which can result from disruptions in the cell cycle.

Front

What are proteins?

Back

Proteins are organic macromolecules made up of chains of amino acids that serve as structural components and perform various functions in organisms.

Front

What is the nucleus?

Back

The nucleus is a membrane-bound organelle found in eukaryotic cells that contains the cell's genetic material (DNA).

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating evolutionary relationships.

Front

How is genetic information transferred from DNA to proteins?

Back

Genetic information is copied from DNA to mRNA, which then leaves the nucleus and travels to ribosomes where proteins are synthesized.

Front

What is the function of ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating mRNA into amino acid sequences.

Front

What are the main differences between eukaryotic and prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common evolutionary origin.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are carbohydrates?

Back

Carbohydrates are organic macromolecules made of sugar molecules that provide energy and structural support in organisms.
