Unit 6: Evolution

Front

What is speciation?

Back

Speciation is the evolutionary process by which new biological species arise. It occurs when populations of a species become isolated and evolve independently, leading to the formation of distinct species that do not interbreed.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and organelles. They are larger than prokaryotic cells and include all plant and animal cells.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell. They produce energy in the form of ATP through cellular respiration, which is essential for carrying out cellular functions.

Front

How many chromosomes do daughter cells have after mitosis if the parent cell has 8 chromosomes?

Back

Each daughter cell will have 8 chromosomes after mitosis, as mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell.

Front

What is the role of the nucleus in a cell?

Back

The nucleus contains the cell's DNA, which controls the cell's functions and the production of proteins. It acts as the control center of the cell.

Front

What is coevolution?

Back

Coevolution is the process where two or more species influence each other's evolution. This often occurs in mutualistic relationships, such as between pollinators and flowering plants.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, typically due to environmental changes, loss of habitat, or inability to adapt.

Front

What is punctuated equilibrium?

Back

Punctuated equilibrium is a theory in evolutionary biology that proposes that species remain relatively stable for long periods, interrupted by brief periods of rapid change and speciation.

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide. It includes interphase (growth and DNA replication) and mitotic phase (cell division).

Front

What is chromatin?

Back

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells. It condenses to form chromosomes during cell division.
