many radioactive atoms that have large masses undergo radioactive decay by releasing a particle that is identical to a helium-4

igomit [66]

The answer is the atomic number and the mass number will decrease.

When atoms undergo radioactive decay, alpha particles release.

Alpha particles consist of two protons and two neutrons. So, mass is 4 (2+2) amu $^{4} _2 \alpha$ .
When an atom of emits an alpha particle, its atomic number will be reduced by 2 and a mass number will be reduced by 4:

$^{A}_ZX$ → $^{A-4}_{Z-2}X$ + $^{4}_{2} \alpha$

Select all that apply. Mutations _____. are random. delete genes from the gene pool. add new genes to the gene pool. are changes

Svetllana [295]

Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)

In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
