Well-executed evacuations are key to minimizing loss of life from tsunamis, yet they also disrupt communities and business productivity in the process.
What is an evacuation?
Answer:- An evacuation shelter is built for longer-term usage; it offers catastrophe survivors who have been forced from their primary dwellings because of natural or man-made disasters a safe, sanitary, and secure environment as well as life-sustaining amenities. A building or earthen mound designed as a place of refuge in the event of a tsunami is known as a vertical evacuation tsunami evacuation building refuge. The shelter is built to withstand an earthquake and resist the effects of a tsunami and is intended for short-term (12–24 hour) protection. It is tall enough to lift refugees above the level of a tsunami inundation.
Therefore, Well-executed evacuation consider the elevation of the community.

Answer:
6,25%
Explanation:
Considering that the couple has a trait of sickle cell anemia, we know that both are heterozygous for the disease (Aa) and therefore can have children with the following genotypes:
Parents: Aa X Aa
Children: AA(A x A), Aa(A x a), Aa (a x A) and aa(a x a)
Knowing that sickle cell anemia only occurs in homozygous individuals, the probability for children to have the disease according to each crossing is:
A x A = 1/4 = 25%
A x a = 1/4 = 25%
a x A = 1/4 = 25%
a x a = 1/4 = 25%
The probability of forming each homozygous child (aa) is 1/4 or 25%. Since they are two children, the probability of both having sickle cell anemia is calculated by multiplying the probability of each, so:
1/4 × 1/4 = 1/16 = 0.0625 = 6.25%
It is concluded that the probability of a heterozygous couple for sickle cell anemia to have two children with the disease is 6.25%.
