-40°F is how many °C?
-8 |
|
\(-{40 \over 9}\) |
|
\({40 \over 9}\) |
|
-40 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
The dwarf planet Pluto is located where?
in the asteroid belt |
|
in the Kuiper Belt |
|
outside the solar system |
|
between the orbits of Jupiter and Saturn |
The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.
When the clouds become too saturated with water, the water is released as precipitation in the form of:
rain |
|
snow |
|
snow or ice |
|
ice |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.
Universal donor blood can be given to a person with any blood type. Which blood type is the universal donor?
O-negative |
|
O |
|
AB |
|
O-positive |
Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.
Most digestion takes place where?
large intestine |
|
mouth |
|
stomach |
|
small intestine |
The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls. These enzymes are produced in the small intestine as well as in the pancreas and liver. After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.
