Solar energy<span> drives the </span>cycle by evaporating water<span> from the oceans, lakes, rivers, and even the soil. Other </span>water<span> moves from </span>plants to<span> the atmosphere through the process of transpiration.</span> Plants put down roots into the soil to draw water and nutrients<span> up into the stems </span>and leaves. Some of this water<span> is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration).

Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.
