|

|
none of these |

-40°F is how many °C?
-8 |
|
\(-{40 \over 9}\) |
|
-40 |
|
\({40 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
A large naturally occurring community of flora and fauna occupying a major habitat is:
a biome |
|
a community |
|
a food chain |
|
a population |

The ovum and oviduct are part of which bodily system?
digestive |
|
circulatory |
|
nervous |
|
reproductive |
Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.
The biosphere consists of which of the following?
all of these |
|
hydrosphere |
|
atmosphere |
|
lithosphere |
The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).
