Hepa filters can efficiently remove microbes from the air (Option a is correct).
<h3>What are Hepa filters?</h3>
Hepa filters, i.e., high-efficiency particulate air filters, are used to separate microorganisms from the air.
These filters (Hepa filters) eliminate over 99% of microorganisms such as bacteria, dust and pollen particles having a size higher than 0.3µm.
In conclusion, Hepa filters can efficiently remove microbes from the air (Option a is correct).

I believe its Frameshift (insertion/deletion) not exactly sure though
Answer:
Explanation:
f(a) = freq of recessive allele
f(A) = freq dominant allele
f(a)^2 = (140/500) = 0,28 -> f(a) = 
= 0,53
f(A) = 1 - f(a) = 0,47
f(aa) = f(a)^2 = 0,28
f(AA) = f(A)^2 = 0,22
f(Aa) = 1- 0,28 - 0,22 = 0,50
