A scanning electron microscope fires electrons at surfaces, and by detecting scattered electrons that reflect off the surface tells something about the surface topography. Transmission electron microscopy fires electrons through thin samples. The scattering of electrons as they go through the sample tells something about the structure. Both types of microscope utilise electrons in order to image a sample.

What is the only reasonable and ethical way to achieve zero population growth
dybincka [34]

Answer:

By not having more offspring.

Explanation:

There are many ways of reaching a zero population growth, but some of them are 0% ethical. But, if the population stops having offspring, there won't be a population growth, instead, the population will decrease in number.

  • In 2017 the country with the biggest population was China, and the country with the biggest population growth in that same year was South Sudan, with a 3,83% population growth, according to statista and IndexMundi
  • Currently, in 2019, China still is the country with the biggest population, and, as for the highest population growth this year, we will only be able to say with 100% certainty when the year ends.

Hope it helped,

Frankenstein was the name of a monster in a popular story about a scientist who built a monster in a lab. However, this species of dinosaurs evolved naturally.
