cientists have used different types of evidence to prove the many changes that have taken place in the universe and on our own planet over time. Living organisms have also adapted to the changing environmental conditions. In this theme there are four contexts: 1 Our changing universe 2 Our changing planet 3 Materials our planet provides 4 Using materials from our planet to make products Additional guidance 2. Knowledge of telescopes should be limited to their use: no working details

microscopic algae‚ called zooxanthellae‚ that live in their tissues. The algae provides the corals with food and oxygen in return for raw materials and a secure place to live. This teamwork is what allows the reef to survive in nutrient-poor tropical seas. This relationship is sensitive to such changes in the environment as cloudy waters or extreme temperatures. The stress on the corals can cause them to expel their algae‚ a phenomenon known as bleaching(Futurists‚ 1993). With the algae

of marine grass and algae. Open beaches with a sloping platform and minimal disturbance are required for nesting. Green turtles apparently have strong nesting site fidelity and often make long distance migrations between feeding grounds and nesting beaches. Hatchlings have been observed to seek refuge and food in Sargassum rafts | What does it eat? | Hatchling green turtles eat a variety of plants and animals‚ but adults feed almost exclusively on sea grasses and marine algae. |

CORAL REEFS ← Coral reefs are living things made of coral polyps. Coral reefs are large strips of wave-resistant coral rocks built up by carbonate organisms lying close to the surface of the sea and even sometimes rising above the sea level. In the Caribbean‚ there are generally three types of coral reefs: ← Barrier reefs are to be found parallel to the coast and are usually separated by a shallow but wide area of water called a lagoon. Belize has one of the second largest barrier

Catfish from Vietnam experience shorter growing times‚ no need for monitoring oxygen level‚ and can be harvested year-round. Third‚ Vietnam does not have to deal with the problem of pond algae. Pond algae gives catfish a muddy smell and distorts the flavor and delay’s pond harvesting in the U.S.‚ to manage this algae problem U.S. catfish farmer have to use pesticides to protect the flavor. From these three points Vietnam has a clear comparative advantage over the U.S. in the production of catfish

phenotypes and gene expressions of the two strains. The aim of this research is to analyze the differentially methylation regions (DMR) between the two strains and identify potential links to the expressions of genes related to calcification. Marine algae are the oldest members of the plant kingdom. Unlike plants‚ they do not have real roots‚ stems‚ leaves‚ and flowers. They are situated based on food chain

is based on the presence of cell wall. But prokaryotes and eukaryotes are widely differed in other characteristics. It included the unicellular and the multicellular organisms in same group. E.g. Chlamydomonas and Spirogyra were placed under algae. It did not differentiate between the heterotrophic fungi and the autotrophic green plants. Fungi have chitinous cell wall while the green plants have cellulosic cell wall. Five Kingdom Classification - It is proposed by R.H. Whittaker (1969)

aquatic plants and algae. Excessive growth of these types of organisms consequently clogs our waterways‚ use up dissolved oxygen as they decompose‚ and block light to deeper waters. The main cause of water pollution are fertilizers and nutrient pollution. Some of the pollutants that are most prevalent in the manure‚ sewage and chemical fertilizers are Nitrates and phosphates. These pollutants run into the streams and rivers causing excessive growth in aquatic plants and algae leading to clogged waterways
