<span>The situation is one similar to the development of antibiotic resistance. The initial five years of spraying wiped out most of the pests; however, the killing also helped the pesticide-resistant pests to survive and thrive since they had less competition. Over the period of five years, the pesticide resistance became more and more common among the beetles and in the eighth year, almost all of the beetles were resistant to the pesticide. Thus, the answer is D.</span>

Explanation:
I know because I'm different breed
Only the successful competitors will reproduce, mortality<span> is very high. Four (4) conditions for natural selection. Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.</span>
The correct answer is option (a) Scanning tunneling microscope.
Microscopes are used to see the objects at molecular level. Scanning tunneling microscope( STM) is a type of optical microscope that uses optics(light) and lenses to see the enlarged size of the object. This microscope use a small metal tip under a high voltage. when this tip of microscope is brought close to the metal, the metallic tip of microscope draws electrons from the atom (metal) to be observed. This generates an electric current. There is a computer system attached to the microscope that detects the change in the electric current. Computer plots the change in position of atoms in metal.
