Because of the changing attitudes towards the usefulness of dams and their possible harm to the environment, ----. the most famous dam failure in the US was that of the South Fork Dam in May 1889 dams were also used to avoid flooding and to facilitate transportation dams were already being built to provide water storage and irrigation even before the advent of written history advances in dam engineering in the first half of the 20th century led to the golden age of dam construction more than 500 dam removal projects were carried out in the US during the last decades of the 20th century None 2. ----, but there have been several periods during which climate has drastically shifted, either locally or globally. Global warming has been an important subject of the political debate There has never been anything directly comparable to the current cycle of human-induced global warming The world's reef systems have been facing overwhelming stress due to global warming Global warming requires joint efforts of governments and international organisations Scientific projections with respect to global warming depend on the study of the past None 3. Despite the possibility of ending abruptly with the return of adequate rainfall, ----. a severe drought, in 1988, hit the sites in Minnesota where the researchers had been measuring species richness the effects of a drought on the landscape and its inhabitants may last for years tropical savanna is a type of grassland that is characterised by seasonal droughts the intensity of a drought is measured largely by the ability of the living things to tolerate it droughts might have also had an enormous impact on people in other dry regions of the world None 4. Although the commonly known honeybee species are native to Europe and Africa only, ----. Although the commonly known honeybee species are native to Europe and Africa only, ----. honey is, today, still valued as a sweetener and is used to some extent in medicine the natural home for a honeybee colony is mainly a hollow tree, log, or cave honey was a precious commodity in early Roman, Greek, and Egyptian civilisations humans have transported them to other continents and places where they have flourished None 5.

Because the populations of ducks have been badly depleted by overhunting, ----. the best aquatic habitat for ducks are those with relatively shallow water lead shot is an important type of toxic pollution that kills large numbers of ducks the loss of natural cavities has been an important cause of the decline of the wood duck conservation has become a high priority for several governments and private agencies the most important breeding habitats for ducks in North America occur in the fringing marshes None 7. Viruses do not feed or grow, and they cannot reproduce on their own; ----. instead, they hijack living cells and force them to make copies of themselves for example, antibiotics are not effective against viruses however, the taxonomy of viruses is done by a number of internationally recognised authorities that is, they can only be seen with an electron microscope since they are very small nevertheless, no one knows exactly the source where viruses came from None 8. Biologists have identified more than 500,000 species of plants in the kingdom Plantae ----. as roots require oxygen for respiration, which is why most plants cannot live in soil that lacks air spaces since photosynthesis takes place in organelles called chloroplasts in plants although there are still plenty of undiscovered species found in the tropics because the seed plants are the dominant and most studied group of plants if they undergo developmental changes, known as morphogenesis, while growing None 9. Solar eclipses are not actually rarer than lunar eclipses, ----. in fact, they occur in equal numbers, usually about two of each per year as a result, a total solar eclipse only casts a shadow about 480 km wide across the Earth that is, a lunar eclipse occurs when the Earth passes between the Moon and the Sun although many people miscalculate when exactly a lunar eclipse will be visible to the eye therefore, these events had a religious purpose for some old civilisations None 10. Artificial vision implants are often able to improve one’s ability to recognise shapes and movements----. whereas a number of varying designs are being used in clinical trials because they may sometimes not be compatible with the patient although the implants have made life easier for those with poor vision since the resolution of the artificial systems is an important consideration in their design even though none of the currently available technologies restores full vision None Bu testle ilgili yorumlarını aşağıdaki kutucuğa bırakabilirsin.
