In cell biology, where does DNA replication take place?
cytoplasm |
|
mitochondria |
|
nucleus |
|
Golgi apparatus |
The cell nucleus contains the genetic material of the cell and is where DNA replication takes place.
Neurons are part of the __________ nervous system.
autonomic |
|
peripheral |
|
central |
|
somatic |
The nervous system consists of the brain and spinal cord (central nervous system) and the peripheral nervous system which is the network of nerve cells (neurons) that collect and distribute signals from the central nervous system throughout the body.
During continental drift, the drifting plates move across which of the following?
water |
|
sediment |
|
liquid mantle |
|
fault lines |
The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.

|
vitamin D, calcium |
|
iron, calcium |
|
vitamin D, magnesium |
Vitamin D helps calcium strengthen bones while also aiding muscle, nerve, and immune system function.
Which of these is not a phase in cell division?
megaphase |
|
cytokinesis |
|
interphase |
|
anaphase |
Cell division is the process by which cells replicate genetic material in the nucleus and consists of several phases, beginning with interphase and ending with cytokinesis.
