It's a way of protecting the trees, and making sure they survive the winter and beyond. Leaves die during the winter months. If those dead leaves stayed on the trees, and new ones wouldn't grow in their place, the tree would have no way of making food for themselves.

Explanation:
In the 1920s, Russian Chemist A.I Oparan and English geneticist Haldane, first conceived and developed independently, the theory of Primordial soup. The primordial soup theory suggests that life began in a pond or ocean as a result of the combination of the right amounts of chemicals from the atmosphere and some form of energy, under the right conditions, which resulted in the production of amino acids, the building blocks of proteins from which life evolved. This is suggested to have happened 3 to 4 billion years ago.
This theory was tested by Chemist Stanley Miller and Physicist Harold Urey, in 1950. They mixed gases thought to be present in the primitive earth and electrically sparked the mixture, which resulted in the formation of amino acids.

Answer: (B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings.
Explanation:
Global warming is a phenomena of the environment. In this the earth atmosphere is affected by the harmful greenhouse gases. The majority of the greenhouse gases are produced by the virtue of burning of the fossil fuels. The burning of the fossil fuel liberates gases which are toxic. These gases have a diatomic structure, which enable them to absorb the heat energy from the sunlight. Thus these gases make the atmosphere hot. As a result of this the atmosphere of earth is becoming warm globally and glacier region is depleting.
