If a star is a brilliant blue color, it's really hot and emits a lot of energy. If it's red, it has a cool surface temperature instead. Therefore, the dominant wavelength of a star's light can tell us its surface temperature.
The correct answer is C. They provide materials organisms need to build their bodies
They are all around us and are essential for all things organic, which means all life forms. They are also important for the creation of energy.

Answer:
D. 0.5 ft
Explanation:
Using the scale :
1 : 4000
This means that an altitude of 4000 feets is represented by 1 unit in the model.
Hence,
1 feet in model = 4000 feet actual altitude
Given an actual altitude of 2000 feets above ground level ;
Feets in the model will be x
1 feet = 4000 feet
x = 2000 feet
Cross multiply :
4000x = 2000
Divide both side by 4000
4000x / 4000 = 2000/4000
x = 0.5
Hence, 2000 feets above ground level corresponds to 0.5 feets in model
Answer:
A is the substrate and B is the protein
Explanation:
Substrate: thing that is the initial part of a protein reaction
