4. The two major threats of burns are? a. Loss of skin and infection
b. Dehydration and Discoloration
c. Discoloration and Loss of Skin
d. Infection and Dehydration

A

Explanation:

Id say A because dehydration has to do with the lack of water, and we are talking about burns. Discoloration might make sense in context such as the skin around the burn was dark and discolored. But actually loosing your skin and getting an infection in that open wound sounds much worse

food production.

Explanation:

food plants need water to survive. Salt soaks water from a source of it If the slat buildup occurs in that water supply then the plants will not have anything to use to get their glucose to make food. This then leads to the con of the plants dying and the people having a loss of food production.

hope this helped!
