An element in the physical state of __________ maintains neither a constant volume nor a constant shape.
solid |
|
gas |
|
plasma |
|
liquid |
The gaseous state occurs at a higher temperature range than the solid and liquid states of the same substance. In this state, molecules flow very freely around each other and will spread out as far as they're able. Gases maintain neither a constant volume nor a constant shape.
Which of these is not a function of bone in the human skeletal system?
protect bodily organs |
|
produce blood cells |
|
store vitamins |
|
store minerals |
Hard bones provide primary support for the endoskeleton while more flexible cartilage is found at the end of all bones, at the joints, and in the nose and ears. In addition to providing support and protecting bodily organs, bones also produce blood cells and store minerals like calcium.
212°F is how many °C?
\(135 {5 \over 9}\) |
|
100 |
|
0 |
|
-100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
In cell biology, cytokinesis results in two separate:
chromatids |
|
chromosomes |
|
cells |
|
nuclei |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
inherent |
|
potential |
|
kinetic |
|
gravitational |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
