Answer:
12.19 hours prior to discovery was the corpse placed in the desert.
Explanation:
Heat required for fly eggs to develop into first instar larvae = 
From the given,
Exposure time = 16 hrs
Temperature = 27 C

The day time exposed hours is 10 hrs.-(7.00am-5.00pm)

So, the extra heat = 427.2-378= 49.2
The addition heat divided by average temperature.
Average temperature = 22.4 C

So, the total time exposed is night time hours to day time hours.
= 10+2.19 = 12.19 hrs.
Therefore, 12.19 hours prior to discovery was the corpse placed in the desert.
The answer is A. Permeability.
I don't understand what you mean??
The major drawback of fossil fuels is that they warm the planet i.e. they cause global warming.
The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is:
Fuel + O2 → CO2 + H2O + ENERGY
<h3>
Disadvantages of Fossil fuels</h3>
The term "fossil fuels" refers to flammable organic geologic formations, including dead organic matter that has been buried hundreds of feet beneath sediment.
- Fossil fuel emissions include various oxides, such as carbon, nitrogen, and sulfate, which cause acid rain and harm the soil's fertility and water quality.
- Both coal and petroleum burning discharge a significant amount of pollutants into the atmosphere, contributing to pollution levels.
- Gases like carbon dioxide are released through the burning of fossil fuels, which aids in climate change.
