Explanation:
The civil rights movement was a struggle for social justice that took place mainly during the 1950s and 1960s for Black Americans to gain equal rights under the law in the United States. The Civil War had officially abolished slavery, but it didn’t end discrimination against Black people—they continued to endure the devastating effects of racism, especially in the South. By the mid-20th century, Black Americans had had more than enough of prejudice and violence against them. They, along with many white Americans, mobilized and began an unprecedented fight for equality that spanned two decades.

Answer:
coevolution
Explanation:
Male euglossine bees harvest the pollen and fragrance compounds from orchids, typically a specific species, and display these in various ways. The female euglossine bee is thought to choose a mate based on the quantity and/or quality of fragrance mixtures presented. The orchids pollinated by these bees have evolved elaborate trapping mechanisms that will often only allow a single species of bee to enter and collect the fragrance; the trap will then force the bees to exit in a way that attaches the orchid's pollen to them. The elaborate courtship ritual and flower development both act to enhance the reproductive success of the insect and orchid, respectively. This is an example of coevolution.
Coevolution occurs when two or more species reciprocally affect each other's evolution.
Answer:
There is no short answer.
Explanation:
Underdamped motion can be described as the type of motion where if the system is affected by a force, the oscillations of the movement slowly decreases until it reaches to an equilibrium. An example the underdamped motion can be a door that automatically closes with the help of a spring. If underdamped, the door swings back and forth until it stops.
Critically damped motion can be described as where the system does not oscillate and returns to its equilibrium as quickly as possible. Going with the door example, if the system is critically damped, the door closes as soon as it is released and does not move anymore.
Overdamped motion can be described as where the system again does not oscillate and returns to its equilibrium point but does so more slowly than the critically damped system. This time the door closes without swinging but its motion is much slower compared to the previous example.
Resonance can be described as a force or a wave of any kind overlapping with another with the same frequency and therefore amplifies the original amplitude of the force or wave. An example to this concept can be a swing, when pushed at the same frequency, its motion becomes bigger.
