Plant cells may generate energy through which of the following?
anaerobic respiration |
|
aerobic respiration |
|
all of these |
|

Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
Within DNA, a variety of a particular gene is called a(n):
allele |
|
heterozygous |
|
chromosome |
|
homozygous |

Cirrus clouds are thin, wispy clouds composed of ice crystals. At what elevation to cirrus clouds form?
high-altitude |
|
low-altitude |
|
mid-altitude |
|
ground level |
Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.
