Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.

B) inheritance of acquired characteristics
C) change in response to need
D) a process of constant improvement, leading eventually to perfection
E) survival of the fastest
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
Due to genetic changes and the environmental conditions when the organism adapts itself to the current situation for survival is called natural selection.
Natural selection means that the organism that survived over another have better traits and characteristics for adaptation.
The correct answer is:
Option A. differential reproductive success based on inherited traits.
This can be explained as:
A particular type of trait carried by an organism that is better for adapting to survival than the other organism carrying less favorable trait will have a better chance of survival and their reproductive success will be much higher.Based on the inherited characteristics the natural selection will be based on reproductive success.Differential reproductive success is an analysis in which comparison is done among the organism that survived and those that did not.Comparing their traits and characters can give an idea about the factor affecting the selection.Therefore, differential reproductive success based on inherited traits best expresses natural selection.
