Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the result of mitosis?

Back

Two cells with genetic material identical to the parent cell.

Front

What is active transport in cells?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy (ATP).

Front

What is the best evidence of active transport?

Back

ATP is being rapidly consumed near the cellular membrane.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

In which populations does genetic drift most often occur?

Back

In small populations.

Front

What determines the order of amino acids in a protein?

Back

The sequence of nucleotides in the DNA located in the nucleus of the cell.

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the instructions for the sequence of amino acids in proteins.

Front

What is the classification system of organisms?

Back

A hierarchical system used to categorize and name organisms based on shared characteristics.

Front

Why does the classification system change?

Back

Technological advances have allowed scientists to better compare organisms.
