<h2>Answer: </h2>

A- Crest.

B- Wavelength.

C- Equilibrium.

D- Trough.

E- Amplitude.

<h2>Explanation: </h2>
  1. A crest is the point on a wave of maximum value of upward displacement within a cycle.  
  2. Wavelength is the distance between two identical adjacent points in a wave.
  3. Equilibrium is a state of balance between opposing forces; a state of balance in which opposing forces cancel one another.
  4. A trough is just the opposite of a crest, so it is the minimum(downward displacement) or lowest point of a wave in a cycle.
  5. Amplitude of a wave is the maximum distance or displacement moved by a point on a vibrating body or wave. Amplitude of a wave is directly proportional(∝) to the amplitude of the vibrating object(source).

Result: Crest, wavelength, equilibrium, trough and amplitude is the correct answer.

Answer:

<h2>A. Chromosome</h2>

Explanation:

In intermediate phase of cell cycle, DNA replication occurs (in S-phase), so in inter phase, DNA become unfolded and in relaxed state and is available for replicating machinery.

When cell enter into prophase, DNA folds, coils and super coils and finally become in condensed form, which can be seen by microscope.

So this compact form of DNA is called as chromosome.

In humans. there are total 46 chromosomes.
