212°F is how many °C?
-100 |
|
\(135 {5 \over 9}\) |
|
0 |
|
100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
A dominant trait will be expressed when paired with:
a dominant trait |
|
a recessive trait |
|
a gene |
|
a chromosome |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.

secondary or tertiary consumers |
|
primary or secondary consumers |
|
secondary consumers or scavengers |
|
primary or tertiary consumers |
Secondary or tertiary consumers may be omnivores.
The crust and upper mantle of the earth is called the:
hydrosphere |
|
lithosphere |
|
atmosphere |
|
geosphere |
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).
