Answer:
A. improve the conditions of people in other countries.
Answer and Explanation:
The father had 54% of the body covered by burns, since a little more than half of his body was burned. In addition, to calculate the percentage of body burn, the following values are considered: head, arms and legs - 9% torso front - 18% torso back - 18%. In addition, the father feels little pain in his legs (which had worse burns) because the third degree burn destroys the nerve endings, while the second degree burn only damages these endings promoting intense pain.
The daughter had 9% of her body burned by first degree burns, which corresponds to her lower limbs. These burns involve the skin and the epidermis, for this reason, we can say that the legs are the part of the daughter's body that has compromised hair and epidermis.
The answer to this question is estuaries or mangrove swamps, which are found in estuary environments. Estuaries are the transition between fresh water rivers and the ocean, and the salinity of estuaries change dramatically depending on the relative dominance between the fresh water and marine environments. These are euryhaline species that can tolerate a wide range of salinities, and include mangrove swamp and certain fishes.
