This is true. There are a few websites online that talk about how it happens, I suggest looking them up.
Explanation:
the first one and the last one is transverse
Difference between Alpha, Beta and Gamma Radioactive Decay. Difference between Alpha, Beta and Gamma radioactive decay can be summarized as follows: Alpha decay forms new element with two fewer protons and two fewer neutrons; Beta decay forms new element with one more proton and one fewer neutron.
By using both of these schemes, energy source and locomotion, amoeboids can be classified properly. Both schemes play an important part of amoeboid’s taxonomy classification because these organisms changes its shape when feeding. Amoebas are traditionally classified under sub-phylum Sarcodina, single-celled with pseudopods (use for locomotion) but recent studies show that they are not monophyletic and actually belong to other groups of organisms — with locomotion and source of nutrients as basis.
