<span>The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". It is composed of cutin, a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water.</span>
Science and technology have influenced everyday life for thousands of years. If it hadn't we would still be living in caves and struggling to stay alive. Everything you see around you is a form of technology. Science itself can be considered a form of technology because it has helped us advance as humans and become more able to overcome disease and predators. Most humans today wake up and are subjected to technology's control because we've fed into it so much that it would extremely hard, if not impossible, for us to survive without it.
<span>The sunspots are eruptions of heat and light energy emitting from the surface of the sun. These can increase our energy absorption many times above normal. Especially if it is pointed directly at the earth. These have been known to disrupt several bands in the radio spectrum and have knocked out communications of satellites. Naturally all this energy would have a great effect on our earth in many ways, climate included.</span>
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.
