The dwarf planet Pluto is located where?
outside the solar system |
|
between the orbits of Jupiter and Saturn |
|
in the Kuiper Belt |
|
in the asteroid belt |
The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.
The process of diffusion allows __________ to exchange oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells.
red blood cells |
|
veins |
|
capillaries |
|
arteries |
Capillaries are small thin-walled vessels that permit the exchange of oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells. This process of exchange is called diffusion.
In cell biology, cytokinesis results in two separate:
chromosomes |
|
cells |
|
nuclei |
|
chromatids |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
50°F is how many °C?
58 |
|
10 |
|
122 |
|
-10 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
Which of these is not a phase in cell division?
anaphase |
|
megaphase |
|
cytokinesis |
|
interphase |
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.
