Plant cells may generate energy through which of the following?
photosynthesis |
|
aerobic respiration |
|
all of these |
|
anaerobic respiration |
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, cytokinesis results in two separate:
nuclei |
|
cells |
|
chromatids |
|
chromosomes |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
These clouds grow upward and can develop into cumulonimbus or thunderstorm clouds.
cirrus clouds |
|
stratus clouds |
|
nimbus clouds |
|
cumulus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.
Which of these is not a phase in cell division?
anaphase |
|
interphase |
|
megaphase |
|
cytokinesis |
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.
The respiratory and circulatory systems are similar in that they:
transport oxygen |
|
deoxygenate blood |
|
add carbon dioxide |
|
transport nutrients |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
