Cirrus clouds are thin, wispy clouds composed of ice crystals. At what elevation to cirrus clouds form?
mid-altitude |
|
low-altitude |
|
ground level |
|
high-altitude |
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.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
sugar |
|
mitochondria |
|
water |
|
oxygen |
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.
50°F is how many °C?
-10 |
|
10 |
|
122 |
|
58 |
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 recognized blood type?
AO |
|
AB |
|
O |
|
B |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
In cell biology, what part of the cell contains organelles?
cell wall |
|
nucleus |
|
cell membrane |
|
cytoplasm |
The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles.
