Answer:
Fossil fuels are fuels that are formed by naturally processes leading to the formation of crude oil, coal and natural gas.
Scientists and engineers have used the energy from these fossil fuels to benefit the society by converting these fuels into consumable products for engines which are used for various daily life routine, such as transport (as in the case of the combustible engines in cars, trains, airplanes and ships), power generation (as in the case of gas turbines for power generation, petroleum or diesel for the engines of power generators) and even for home use in food processing (as in the case of cooking gas).
The chemical reaction mostly involved in this process especially in the case of engines is combustion reaction. Combustion reaction is an exothermic reaction in which an organic substance is burnt in excess oxygen to produce carbon dioxide. The energy conserved in this reaction (combustion reaction) is from stored potential energy (in the form of chemical energy) to thermal energy (which is the heat released when the hydrocarbon is burnt).
As mentioned earlier, one of the methods of using fossil fuels for energy is it's use in power generation by power generating sets (generators) and gas turbines. One advantage of using fossil fuel products for power generation is that it is cheaper than it's alternatives (such as solar power generation). However, one disadvantage of using fossil fuel products for power generation is that they release toxic gases/chemicals (such as carbon monoxide, CO, nitrogen oxides, NO and NO₂) into the atmosphere.
Explanation:Fossil fuels are use in power plants to make steamAlternative, renewable energy sources, such as wind and solar power, eliminate the pollution that accompanies fossil fuel energy
- Photosynthetic organisms, also known as photoautotrophs, are organisms that are capable of photosynthesis.
- Some of these organisms include higher plants, some protists , and bacteria because we know that photosynthesis is a process that plants use, we can define photosynthetic protists as 'plant-like' protists that get their nutrients by converting sunlight into energy using photosynthesis.
- Protists can be photosynthetic or heterotrophs (organisms that seek outside sources of food in the form of organic material).
- They also contain chlorophyll, a pigment which absorbs light energy for photosynthesis. Photosynthetic protists are considered plant-like protists.

The tubes and bottles are autoclaved in order to sterilize the nutrient broth and nutrient agar.
<h3>What do you mean by sterilize?</h3>
To rid (something or someone) of all live microbes in order to make it sterile (as by the use of steam or dry heat) Use an autoclave to sterilize surgical instruments. to surgically sterilize cats and dogs in order to remove their reproductive ability.
<h3>How do we sterilize?</h3>
Combining heat, chemicals, irradiation, high pressure, and filtration can result in sterilization. Examples include the use of steam under pressure, dry heat, UV radiation, gas vapor sterilant, chlorine dioxide gas, etc.
<h3>What makes sterilization important?</h3>
To stop the spread of diseases linked to the usage of an object, sterilization eliminates all bacteria on its surface or in its fluid.

The answer is A)Biodiversity
Answer:
As the temperature increases so does the amount of moisture that the air can hold.
Explanation:
The graph shows that at 0 degrees C air can hold about 5 g/m cubed while at 20 it can hold 19 g/m cubed meaning that the amount of moisture increases as temperature increases.
