neutron |
|
proton |
|
electron |
|
isotope |

In cell biology, cytokinesis results in two separate:
chromatids |
|
nuclei |
|

During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
Convert 5C° to F°.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
