C. Developing effective methods of food preservation
Explanation:
The development of effective methods of food preservation is a much more smaller and manageable problem that contributes to the complex problem.
The percentage of food rotting is not as a result of lack of an effective preservation technique as highlighted in the passage. It is due to the long distances of agricultural area from where the farms are located.
- To cut the loss, efficient and rapid transportation techniques needs to be put in place to carry the fruits and vegetables to the area where they are needed.
- This is the most complex problem that if solved can peg back food rot.
- Additional measures should be put in place to preserve the food.

Explanation:
Sodium fluoride - 5-chloro-2-(2,4-dichlorophenoxy)phenol (1:1:1) | C12H7Cl3FNaO2 |
1.it is readily available since hydrogen is a basic earth element and it's very abundant.
2. It doesn't produce harmful emissions.
Disadvantages
1.it is expensive. It is expensive because it takes a lot of time to separate the element from others.
2.it is difficult to store. Even moving a tiny bit of hydrogen would be very expensive.
3. It is highly flammable. Since it is a very powerful source of fuel, hydrogen can be very flammable.
Simple. The atomic number is the number of protons (12) and the mass number is the number of neutrons and protons combined. So you'd subtract 12 from 25 (25-12=) and that'd get you 13 as your answer. If you need to find the number of electrons, it'll be the same as the number of protons unless it has a certain charge and if it does, if it's positive it has more protons (+) than electrons (-), if it is negative it has more electrons (- negatively charged) than protons (+ positively charged)
Answer: increased
Explanation:
Powdered zinc has a greater surface area than zinc granules. If the same mass of zinc and volume of acid is used, it will be observed that the powdered zinc will react faster since it provides a greater surface area for reaction compared to zinc granules. The greater the available surface area of reactants, the greater the rate of reaction. Higher surface area means that more particles are available for reaction.
