Fuel combustion from motor vehicles (e.g. cars and heavy duty vehicles)
Heat and power generation (e.g. oil and coal power plants and boilers)
Industrial facilities (e.g. manufacturing factories, mines, and oil refineries)
Municipal and agricultural waste sites and waste incineration/burning
Residential cooking, heating, and lighting with polluting fuels
Answer:
Chloroplasts are chlorophyll-containing organelles found in plants, algae, and cyanobacteria (etc).
Law of demand
The regulation of demand for states that because the rate of a great decrease, the amount demanded of that correct increases.
<h3>What are the five Determinants of Demand?</h3>
The five determinants of demand are:
- The rate of the goods or service.
- The earnings of consumers.
- The expenses of associated items or services—both complementary and acquired together with a selected item, or substitutes sold rather than a product.
- The tastes or alternatives of customers will pressure demand.
- Consumer expectancies about whether or not charges for the product will upward push or fall withinside the future.
For combination demand , the wide variety of customers withinside the marketplace is the 6th determinant.

To fully understand the processes occurring in present-day living cells, we need to consider how they arose in evolution. The most fundamental of all such problems is the expression of hereditary information, which today requires extraordinarily complex machinery and proceeds from DNA to protein through an RNA intermediate. How did this machinery arise? One view is that an RNA world existed on Earth before modern cells arose (Figure 6-91). According to this hypothesis, RNA stored both genetic information and catalyzed the chemical reactions in primitive cells. Only later in evolutionary time did DNA take over as the genetic material and proteins become the major catalyst and structural component of cells. If this idea is correct, then the transition out of the RNA world was never complete; as we have seen in this chapter, RNA still catalyzes several fundamental reactions in modern-day cells, which can be viewed as molecular fossils of an earlier world.
