<u>Answer:</u>
There are under-funded schools in Guatemala where they don’t have many resources.
<u>Explanation:</u>
- Though education in Guatemala is compulsory for six years, the status of primary and secondary education there is one that can be called the poorest.
- Most schools are poverty-stricken and lack the most basic facilities that are necessary for the schools to run smoothly.
- The funds spent by the government on the betterment of education facilities are negligible, thus leaving the schools in great distress.
Technological innovations like desalination allowed people living in areas without adequate freshwater sources to adapt to their environment because desalination allows people to live, grow food, and mine natural resources in regions without many freshwater resources.
Desalination is that the process of removing salts or other minerals and contaminants from seawater, brackish water, and wastewater effluent and it's an increasingly common solution to get water for human consumption and for domestic/industrial utilization.
Desalination uses reverse osmosis technology to remove water molecules from seawater.
Desalination could be a process that takes away mineral elements from saline water.
The process is named "desalination", and it's being employed more and more round the world to grant people with needed freshwater.

Secondary reinforcers are learned or conditioned. An example of a secondary reinforcer is grades or money. Secondary reinforcers are learned and are reinforced by the continual use of the reinforcer. Primary reinforcers are biological and include food, drink, and pleasurable activities.

Answer:
Surfactant increases airflow. It has this effect on airflow because it reduces resistance to lung inflation. Airflow increased as predicted.
Explanation:
Pulmonary surfactant is a complex mixture of lipids and proteins secreted by the Type II alveolar cells. The major component of surfactant, dipalmitoyl-phosphatidylcholine (DPPC), is an amphiphatic phospholipid. The main function of the pulmonary surfactant is to reduce the surface tension at the air/liquid interface in the lungs by forming lining layer between the aqueous airway liquid and the inspired air. prevents alveolar and airway collapse at end-expiration and thus allows cyclic ventilation of the lungs. It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. By lowering alveolar surface tension, pulmonary surfactant provides two important benefits:
(1) it increases pulmonary compliance, reducing the work of inflating the lungs; and
(2) it reduces the lungs’ tendency to recoil, so they do not collapse as readily.
