In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
water |
|
mitochondria |
|
oxygen |
|
sugar |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
In cell biology, where does DNA replication take place?
cytoplasm |
|
mitochondria |
|
Golgi apparatus |
|
nucleus |
The cell nucleus contains the genetic material of the cell and is where DNA replication takes place.

shingles |

anemia |
|

Atoms of an element whose atoms can vary in the number of neutrons in their nucleus are called which of the following?
products |
|
reactants |
|
ions |
|
isotopes |
The atomic mass of an element listed in the Periodic Table represents the average mass of a single atom of that element and is measured in atomic mass units (amu). This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.
