Answer:
The major remaining problem was the large distances driven daily by solitary commuters
Explanation:
Photochemical smog occurs when nitrogen oxides and volatile organic compounds mix together in the presence of sunlight which acts as a catalyst and form ozone at lower levels.
Even though measures such as ban of incinerators and regulation of evaporation of gasoline were instated photochemical smog was still present because people drive for a long time to get to work.
As far as photochemical smog is concerned it the combustion of other fossil fuels, such as gasoline by motor vehicles and industry is seen as its main contributor. Combustion releases primary pollutants: volatile organic compounds and nitrogen oxides. These pollutants are the main cause of photochemical combustion.
Based on the organization of plants and animals at a cellular level, the following is true:
- 1) Membrane protein complexes that strengthen the adhesion between adjacent cells, like rivets, to protect against pulling forces. - Desmosomes - Animal.
- 2) Small channels that form across the plasma membranes of adjacent cells; especially important in intercellular communication. - Gap junctions. - Animals.
- 3) Membrane proteins that create watertight seal between cells. - Tight junctions - Animals.
- 4) Small channels between cells that are otherwise surrounded by walls; enable movement of water and solutes between cells. - Plasmodesmata - Plant.
- 5) A polysaccharide that is used to synthesize cell walls, which protect cells and help maintain their shape. - Cellulose - Plant.
- 6) Long fibers of protein found in the extracellular matrix that provide structural support for cells. - Collagen - Animal.
<h3>Features of plant and animal cells</h3>
Animals are known to desmosomes, gap junctions, tight junctions, and collagen to help cells fulfil their duties and keep the body functioning.
Plants have plasmodesmata, and cellulose which ad the plant by helping cells perform their functions.

I believe the answer is: Cyclones.
Cyclones happen when a mass of air rotates on strong center within the low atmospheric pressure.
This mass of air is often accompanied by thunderstorms and could be originated from both tropical or subtropical waters.
Charles Darwin traveled to the Galapagos Islands and observed that there were several different types of species of finches and tortoises. These different species of animals were contained to separate islands, all tailored fit for each island. This gave Darwin the idea that species evolve over time into new species.
