Answer:

Copper is a 100 percent recyclable material. According to the Copper Development Association, copper's recycling rate is higher than that of any other engineering metal. Every year in the United States, nearly as much copper is recycled as is mined. Excluding wire production, almost 75 percent of U.S. copper used comes from recycled copper scrap. There are so many advantages to recycling copper that the value of scrap is approximately 85 to 95 percent the price of newly mined ore.

const2013 [10]

Answer:

a) i) Xylem

   ii) Upper epidermis  

   iii) Stoma

   iv) Chroloplast  

   v) Palisade cell layer

b) By a waxy layer on the cuticle of the leaf

Explanation:

The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.

The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

Some psychologists suggest that sleep has evolved in order to allow humans to dream.
Kay [80]

Answer:

True

Explanation:

Earlier it was believed by researchers that sleep is not a good thing as it does not allow an organism to stay alert all the time due to which there are high chances of such organism being consumed by other organism. However, with the discovery of theory of evolution, it is now believed that sleep has also evolved. Its evolution allows an organism to save energy and conserve it.  

Evolved sleep has helped decrease synaptic strength which allows a person to preserve memories and function well during the day time. REM sleep in the early morning makes brain metabolically active even while sleeping and hence, dream comes.
