9 amino acids (alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, valine) have no hydrogen donor or acceptor atoms in their side chains.
Answer:
A type of an atom which has a different number of neutrons but the same atomic number, therefore making it the same element. This atom would still have the same properties as well. (Ex: Vanadium-51 is an isotope of Vanadium that has 51 neutrons but still has 23 protons, as its atomic number is 23.)
<u>Answer:</u>
The velocity of the bus be is 0 miles/second
<u>Explanation:</u>
Given, a bus travelled a distance of 20 miles north and 20 miles back to the starting point
Hence, total distance = 20 + 20 = 40 miles
Velocity is calculated by the formula:
Velocity =
Displacement =
Velocity =
Therefore, the velocity of the bus is 0 miles/second
