Alenkasestr [34]

In the pillbug experiment, if the pillbugs in the experimental chamber would have moved to the side of the chamber with sand instead of cornstarch then the Pillbugs tend to prefer sand over cornstarch.

Pillbugs are categorised as terrestrial isopods and are in the crustacea family. The purpose of this experiment is to determine if pillbugs, often known as roly-polys, prefer light or darkness. They are cold-blooded, slow-moving organisms whose environs control their body temperatures.

The pill bugs are the controlled variable, and the behaviour of the pillbug is the dependent variable. The experimental group is housed in a moist environment with water and cornstarch, whereas the control group is in a dry environment with sand.

Why should we pay attention to child survivors of genocide like Inge and Zlata?
ad-work [718]

Answer:

Learn from the experiences of child survivors can encourage government policies to avoid genocide and its atrocious effect on the survivors, especially children.

Explanation:

Inge Auberbacher published "I Am A Star: Child of the Holocaust" as a recollection of her experience in a concentration camp.

Zlata Filipovic wrote "Zlata’s Diary" to describe her experience during the genocide in Sarajevo during the 1990s.

Any study about genocide offers valuable lessons for the present and especially to not allow history from repeating itself.

Particularly, the experiences of child survivors can encourage policies to avoid genocide and its atrocious effect on the survivors, especially children, because they need support to be able to reinsert themselves into society, to understand and help them cope with the trained behaviors they show as a result of their experience, and to help them deal with "survivor's guilt" in a healthy way.
