Biology Basics Quiz

Biology is the scientific study of ______

All organisms are made up of ______ that process hereditary information

Energy processing is important to life as it allows organisms to ______, grow, and reproduce

Biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the ______ around them

During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the M phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells. To ensure the proper replication of ______ components and division, there are control mechanisms known as cell cycle checkpoints after each of the key steps of the cycle that determine if the cell can progress to the next phase.

Life on Earth emerged more than 3.7 billion years ago, is immensely ______

The cell cycle, or cell-division cycle, is the series of ______ that take place in a cell that causes it to divide into two daughter cells. These ______ include the duplication of its DNA (DNA replication) and some of its organelles, and subsequently the partitioning of its cytoplasm, chromosomes and other components into two daughter cells in a process called cell division.

The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.

In ______ cells (having a cell nucleus) including animal, plant, fungal, and protist cells, the cell cycle is divided into two main stages: interphase, and mitosis in the M phase that also includes cytokinesis.

In cells without nuclei the prokaryotes, bacteria and ______, the cell cycle is divided into the B, C, and D periods.
