This organelle is responsible for producing most of a eukaryotic cell’s ATP.

What is the mitochondrion?

100

The molecule that stores hereditary information in most organisms.

What is DNA?

100

Charles Darwin proposed this mechanism as a major driver of evolution.

What is natural selection?

100

These organs filter the blood and produce urine.

What are the kidneys?

100

Plants use this process to convert light energy into chemical energy.

What is photosynthesis?

200

This membrane structure controls what enters and leaves the cell and is primarily composed of phospholipids.

What is the plasma membrane?

200

Different versions of the same gene are called these.

What are alleles?

200

Structures that share a common evolutionary origin but may have different functions are called these.

What are homologous structures?

200

This protein in red blood cells carries oxygen.

What is hemoglobin?

200

The basic unit of classification directly below genus.

What is species?

300

Ribosomes attached to this organelle commonly synthesize proteins that will be secreted from the cell.

What is the rough ER?

300

An organism with two different alleles for a gene has this genotype.

What is heterozygous?

300

A random change in allele frequencies, especially powerful in small populations, is called this.

What is genetic drift?

300

This hormone lowers blood glucose by promoting glucose uptake into cells.

What is insulin?

300

This molecule is considered the main immediate energy currency of cells.

What is ATP?

400

During this phase of mitosis, sister chromatids separate and move toward opposite poles.

What is anaphase?

400

This enzyme synthesizes RNA using DNA as its template.

What is RNA polymerase?

400

A sudden reduction in population size that changes allele frequencies is known as this effect.

What is the bottleneck effect?

400

This chamber of the heart pumps oxygenated blood into the systemic circulation.

What is the left ventricle?

400

In aerobic respiration, this molecule serves as the final electron acceptor in the electron transport chain.

What is oxygen?

500

This cytoskeletal protein forms microfilaments and plays an important role in muscle contraction and cell movement.

What is actin?

500

When two genes are located close together on the same chromosome, they tend to be inherited together due to this phenomenon.

What is genetic linkage?

500

The evolution of similar traits independently in unrelated lineages because of similar environmental pressures is called this.

What is convergent evolution?

500

This part of a neuron commonly receives signals from other neurons.

What are dendrites?

500

This enzyme fixes atmospheric carbon dioxide during the Calvin cycle and is often described as the most abundant enzyme on Earth.

What is RuBisCO?
