<u>ANSWER:</u>
The correct option is B- Qualitative.
<u>EXPLANATION:</u>
When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.
Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
Answer:
These cleaning products break apart the capsules of the viruses causing them to no longer be capable of infecting an individual.
Explanation:
Bleach oxidises organic molecules. This causes proteins to become denatured, or lose their shape. The viral capsule containing the DNA is a coat made up of proteins that is required for the virus to become infectious. Therefore, following bleach treatment, the viral protein capsule become oxidised, cause them to loses their shape, meaning the virus can no longer infect individuals.

Answer:
The unit cell's edge length is 
Explanation:
Number of atom in BCC unit cell = Z = 2
Density of barium metal= 
Edge length of cubic unit cell= a = ?
Atomic mass of Ba(M) = 137.33 g/mol
Formula used :

where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
On substituting all the given values , we will get the value of 'a'.


The unit cell's edge length is
