Answer:
A) It uses less energy to make something from recycled materials than from new materials. 
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch. 
Hence, the correct answer is "A)"
 
        
             
        
        
        
The answer is <span>C. reductions of chromosome number.
Meiosis is also known as a reduction division of the cells. The reason for that is because during meiosis the diploid cells are divided into haploid cells. Meiosis consists of two divisions - meiosis I and meiosis II. In meiosis I, the number of chromosomes is reduced, while meiosis II is similar to mitosis. In both meiosis and mitosis, however, cell division, duplication of chromosomes, and production of new cells are common processes.</span>
