<span>The answer seems to be: 1.Chemical—triggers release of pancreatic enzyme; Physical—triggers stomach muscle contraction. The second choice is wrong since </span>acetylcholine does not directly influence tongue contraction. The third choice is wrong because of the part "<span>Physical—triggers release of pancreatic enzyme" </span>
A.movement and protection
Answer :
Thus, the Beta minus decay of carbon-14 reaction is:
Beta particle
The electron capture equation for the given reaction is:
Explanation :
Beta minus decay : It is a type of decay process, in which a neutrons gets converted to proton, an electron and anti-neutrino. In this the atomic mass number remains same.
The beta minus decay equation is represented as,
(A is the atomic mass number and Z is the atomic number)
Thus, the Beta minus decay of carbon-14 reaction is:
Beta particle
Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.
The electron capture equation is represented as,
The electron capture equation for the given reaction is:
