Answer 1

Answer:

Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology (the study of tissue under the microscope) and in the medical fields of histopathology, hematology, and cytopathology that focus on the study and diagnoses of disease at a microscopic level. Stains may be used to define biological tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells), or organelles within individual cells.

Answer 2

Answer:

Let the number be N

Since the number when divided by 48 leaves a remainder of 31, we have N=48(n)+31 where 'n' is the quotient got by dividing number by 48

We can write N=24×2×n+31=24×(2n)×24+7=24(2n+1)+7

So, when N is divided by 24, remainder left is 7
