Compare ideas about living things before and after the invention of the microscope

The amount of detail was different

Explanation:

Before the invention of the microscope, the scientists depended on the eyes. In addition, they depended on the general magnifying glass. This resulted in the limited details. However, a combination of mirrors and magnifying glass resulted in the better magnification and resolution. In addition, the introduction of transmission electron microscope also made things better. In addition, the microscope could provide more information that would not have been accessed by the naked eye.  

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
