Adaptation of Living Things Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments. Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun’’s energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plants have. Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near. Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions. Some plants and animals develop superior characteristics so that they may______.

Petroleum products, such as gasoline, kerosine, home heating oil, residual fuel oil, and lubricating oil, all come from one source ― crude oil found below the earth’’ s surface, as well as under large bodies of water, from a few hundred feet below the surface to as deep as 25 000 feet into the earth’’s interior. Sometimes crude oil is secured by drilling a hole through the earth, but more dry holes are drilled than those generating oil. Pressure at the source or pumping forces crude oil to the surface. Crude oil wells flow at varying rates, from ten to thousands of barrels per. hour. Petroleum products are always measured in 42-gallon barrels. Petroleum products are different in physical appearance: thin, thick, transparent or opaque, but their chemical composition is made up of only two elements: carbon and hydrogen, which form compounds called hydrocarbons. Other chemical elements found in union with the hydrocarbons are few and are classified as impurities. Trace elements are also found, but these are of such minute quantities that they are disregarded. The combination of carbon and hydrogen forms many thousands of compounds which are possible because of the various positions and joinings of these two atoms in the hydrocarbon molecule. The various petroleum products are refined from the crude oil by heating and condensing the vapors. These products are light oils, such as gasoline, kerosine, and distillate oil. The residue remaining after the light oils are distilled is named as heavy or residual fuel oil and is used mostly for burning under boilers. Additional complicated refining processes rearrange the chemical structure of the hydrocarbons to produce other products, some of which are used to upgrade and increase the octane rating of various kinds of gasoline. Which of the following is TRUE

"I’m sorry, but we never negotiate on the price" means that they do negotiate on (78) things, like the delivery time, or the "extras" that might be available (79) part of the purchase. In the same car showroom, (80) the salesman says, "Sorry, I can’t negotiate prices", then your response should be to ask who (81) the message the salesman is sending suggests that his boss is the one (82) need to be talking to.In all of these situations, the message is (83) communicated in clear terms.
