Answer: option C - The widespread use of antibiotics has led to resistant strains of viruses.
Explanation:
Antibiotics are substances (usually drugs) that can destroy or inhibit the growth of BACTERIA and similar microorganisms.
Do note that viral infection DO NOT respond to antibiotic treatment.
So, it is FALSE to say that the widespread use of antibiotics has led to resistant strains of viruses
-4
Explanation:
If a radioactive isotope undergoes alpha decay, it's mass number will change by -4.
The mass number of a nuclei is the sum of its number of protons and neutrons.
An alpha particle is similar of a helium atom:
⁴₂He
The atom above is made up of:
mass number = 4
Atomic number = 2
Number of protons = 2
Number of neutrons = 2
Number of electrons = 2
If a substance is undergoing radioactive decay, the mass number of the product will decrease by 4 and the atomic number will decrease by 2.
In nuclear equations, mass and atomic numbers are usually conserved.
