Which tool is most likely used to produce a clear image of very tiny structures inside a cell?
Oksanka [162]
Depends on the magnification you are looking for... usually, a light microscope is enough (1000x max magnification)...

An electron microscope is powered by high energy beams and can magnify many times higher than the light microscope (where magnification is limited by the wavelength of light). The magnification of an EM is on the nano scale.

(P.S.: as a chemist, I'd always choose an EM over an optical microscope as I can always zoom in or out depending on my needs) ;)

A population's emigration in one month totaled three individuals. During the same period, immigration was 17 individuals. Natali
Ratling [72]

There was no net change in the given population. The size of the given population remains unchanged.

The explanation behind this is that if we consider the given values-

Emigration- 3

Immigration- 17

Natality- 12

Mortality-26

Therefore,

The overall effect on the population will be=

(Emigration+ Mortality) - (Immigration + Natality)

= (3+26) - (17 + 12)

=29-29

=0

Here the emigration means the number of people who have migrated from the population. Mortality refers to the number of deaths in a given population. Immigration is the migration of people into the population and natality is the overall number of births that have taken place in a population. Therefore there is no net gain or loss in the given population. This exerts no effect on the population keeping it unchanged.
