In cell biology, cytokinesis results in two separate:
cells |
|
chromatids |
|
nuclei |
|
chromosomes |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.

saturated fat |
|
protein |
|

Blood is circulated throughout the body via:
veins |
|
arterioles |
|
capillaries |
|
aorta |
The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.
Which of the following is related to the Cambrian Explosion?
first civilizations |
|
fossil record |
|
carbon dating |
|
extinction of dinosaurs |
The Cambrian period is one of the most significant geological time periods. Lasting about 53 million years, it marked a dramatic burst of changes in life on Earth known as the Cambrian Explosion. It is from this period that the majority of the history of life on Earth, as documented by fossils, is found. Called the fossil record, the layering of these mineralized imprints of organisms preserved in sedementary rock have allowed geologists to build a historical record of plant and animal life on Earth.
Which of these is not a phase in cell division?
cytokinesis |
|
interphase |
|
anaphase |
|
megaphase |
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.
