Answer:
There are 4 tryptophans in the protein.
Explanation:
According to question, protein contains one tyrosine residue and say x number of tryptophans.
Concentration of protein solution = 1.0 micromolar = 
Molar absorptivity of a protein solution : 
Length of the cuvette = l = 1.0 cm
Absorbance of protein solution at 280 nm = A = 0.024
( Beer-Lambert's law)
Solving for x :
x = 4
There are 4 tryptophans in the protein.
Answer:
the first one is protons and electrons the second one is protons the third one is neutrons and the forth one is also neutron
A function describing the location and wave-like behavior of an electron in an atom.

Explanation:
1.Scientists use a shared system for reporting measurements called the International System of Units (SI). We use common measurement systems because science involves a lot of replication to confirm results. The most common system used in science is the metric system.
2.m, kg, m^3
3. g value change
