Answer:
c. uracil
Explanation:
uracil is not found in DNA. the missing base would be thymine
Answer: The approximate molecular mass of the polypeptide is 856 g/mol
Explanation:
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
Or,
where,
= osmotic pressure of the solution = 4.19 torr
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of solute (polypeptide) = 0.327 g
Volume of solution = 1.70 L
R = Gas constant =
T = temperature of the solution =
Putting values in above equation, we get:
Hence, the molar mass of the polypeptide is 856 g/mol
Answer: petroleum
because it is a fossil fuel like coal, and natural gas.
The answer would actually be false. I just took the test.
