What is responsible for the yellow-orange coloration of leaves in the fall?
mixer [17]

The correct answer is - C) carotenoids.

The majority of the trees from the mid-latitude forests tend to shade their leaves in the autumn. This process occurs because of the seasonal changes in the climate, where the trees tend to be almost not-active during the winter, so in order to preserve as much energy and nutrients as possible they get read off their leaves.

It is not a sudden process, but it takes some time, where the leaves from the initial green color start to change to yellowish, than towards orange, reddish, or brownish before they fall.

The reason why this coloration appears in the leaves when the tree starts to process of shading them off are carotenoids. The carotenoids found in the leaves, the lutein and the beta-caroten, thorugh the xantophills and the flavonoids give a yellowish color to the leaves, thus we get the beautiful autumn colors and landscapes.

Strike441 [17]
The major causes of the greenhouse effect is excessive carbon dioxide gas in the atmosphere. The greenhouse effect is a process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by green house gases, such as carbon dioxide, water vapor, metahne, nitrous oxide, and ozone. The absorbed energy warms the atmosphere and the surface of the Earth.

1. inclusion of the environmental costs of fossil fuels in their price

3. a shift of federal subsidies from fossil fuels to renewables

5. fossil fuel industry receives government subsidies

9. increased research and development funding for renewables

Which of the following statements would you classify as causes of the relatively low utilization of renewables in our energy mix? Select all that are true.

4. fossil fuels are far cheaper than renewables

6. fossil fuels are rich in energy

Which of the following statements would you classify as consequences of the relatively low utilization of renewables in our energy mix? Select all that are true.

2. fossil fuel combustion creates smog and acid precipitation

7. greenhouse emissions spur climate change

8. fossil fuel extraction alters and fragments habitat

Explanation:

The relatively low utilization of renewables in our energy mix can be solved by effectively increasing the cost of fossil fuels and reducing the cost of renewables. This can be achieved through one or a combination of the following factors :

Inclusion of the environmental costs of fossil fuels in their price.

A shift of federal subsidies from fossil fuels to renewables .

Fossil fuel industry receives government subsidies .

Increased research and development funding for renewables .

Some of the causes of the relatively low utilization of renewables in our energy mix include the cheaper costs of fossil fuels compared to renewables  and the richness in energy  content of fossil fuels. Other reasons include consumers' unwillingness to adapt to the new technological requirements of renewable energy.  

The consequences of the relatively low utilization of renewable energy in our energy mix include smog and acid precipitation, an increase in greenhouse emissions, and habitat alteration and fragmentation during extraction.
