Explanation:
Beta decay:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle. In beta positive decay proton is converted into neutron and positron, thus the atomic number is decreased by one.
¹¹₆C → ¹¹₅B + ⁰₊₁e
In beta minus decay the one electron is ejected and neutron is converted into proton.
¹⁴₆C → ¹⁴₇N + ⁰₋₁e
Properties of beta radiations:
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminium is used to block the beta radiation

Atoms form molecules. A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds. ... All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms.

Answer:
Selective Breeding
Weeds are bad,
But why is this so?
Just like grass,
They too grow.
Weeds are disliked,
Like the drink that's spiked.
But why is this so?
Who's to say they shouldn't grow?
The weed is unwanted,
Like a murderer hunted.
But what crime did it commit?
Why should it not, be free to sit?
Thickly they may grow,
But grass even more so.
Who's to say they should not grow?
Why should their seed not be sow?
Weeds are bad,
But why is this so?
Just like grass,
They too grow.
If all things living, were for cared,
The land we own, for all shared.
The weed let live,
And life not carefully selected by- siv.
Selective breeding is unfair,
No better than plain warfare...
