Answer
is: mass number stays 184, but atomic number changes.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from an atomic
nucleus.
There are two types of beta
decay: beta minus and beta
plus. In beta minus decay (</span>atomic number Z is increased by one, new element is wolfram W) neutron is converted to a
proton and an electron and
an electron antineutrino.
In beta
plus decay (atomic number Z is decreased by one, new element is hafnium Hf), a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.
Answer:
The correct answer is "8".
Explanation:
The formula to calculate the number of peptides that can be synthesized from a certain number of different amino acids is given as follows:
"n^r"
where "n" is the number of amino acids and "r" is the length of the peptide.
In this case,"n" is 2, since the peptides are synthesized with 2 different amino acids: leucine and histidine; and "r" is 3, since the length of tripeptides is 3 amino acids.
Therefore, the number of distinct tripeptides is given by the formula "2^3", which is "8".
