Use Figure 14.1 аnd the fоllоwing descriptiоn to аnswer the questions below. In а particular plant, leaf color is controlled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true-breeding dark-leaved plant is crossed with a light-leaved one, and the F1 offspring is allowed to self-pollinate. The predicted outcome of the F2 is diagrammed in the Punnett square shown in Figure 14.1, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square. Figure 14.1 Which offspring have dark green leaves?

These forms became the basis for the style of fighting known as kung fu. Over 16 centuries, the monks have used kung fu for self-defense and in war. With it, they have won many battles against their enemies.[B] In Dengfeng today, ten kilometers from the Shaolin Temple, there are over 60 martial arts schools with more than 50,000 students. They come to the schools for a variety of reasons. Some hope to become movie stars. Others come to learn skills that will ensure good jobs in the military or police force. A few are sent by their parents to learn self-control and hard work.[C] Master Hu Zhengsheng teaches at a small school in Dengfeng. Recently, he was offered an important role in a kung fu movie. It would have been good publicity for his school, but he did not accept. He doesn't agree with how kung fu is often shown in movies. He feels they show too much violence.[D] Unlike many large schools, which teach acrobatics and kickboxing, Hu teaches his students traditional kung fu forms. He teaches them the way his master - a Shaolin legend - taught him. But attracting new students to this style of kung fu has become a problem. Hu is afraid his art will soon die out. He has to remind his students that kung fu was designed for fighting, not to entertain.[E] "There are no high kicks or acrobatics here," he says. "It is hard to convince boys to spend many years learning something that won't make them wealthy or famous."[F] Hu's students have little. They sleep in unheated rooms and train outside no matter what the temperature. They hit trees with their bare hands and take turns sitting on each other's shoulders to build leg strength. Why such hardship? To master kung fu, they must learn respect, and how to "eat bitterness," a Mandarin expression meaning "to endure suffering." The life of a Shaolin master, Hu teaches, is not easy or attractive.[G] Master Hu is in a difficult position. For old traditions to survive, the young must learn. Gradually, he has begun offering a few courses in kickboxing and the acrobatic kung fu forms, hoping to attract new students. Then, maybe, he'll be able to convince them to learn Shaolin kung fu the traditional way. What word from paragraph A means the same as forms?

His shelves became filled with a growing collection of fossils. For Hurum, these fossils were not just rocks, but things that could tell the history of life on this planet. He imagined them saying, "I am not a rock. I am a fossil. I have a story to tell." [B] Hurum earned a PhD in paleontology in his native Norway. Since then, he has been on expeditions seeking fossils all over the world. Much of his work has been carried out in Svalbard, a group of Norwegian islands north of the Arctic Circle. In the hills of this cold and remote region, Hurum and his team have found the fossils of many sea creatures. It might seem surprising to find the remains of such animals at the tops of hills, but in prehistoric times, these areas were actually seabeds about 100 meters deep.[C] Hurum has returned to Svalbard many times. The "dig season" in the region is very short - from July to August. During that time, the temperature is just about warm enough to soften the frozen ground, allowing easier access to the fossils. There is also less wind, and the "midnight sun" makes it easy for the scientists to have long, productive days.[D] Even a dream job has its challenges, however. "Sometimes, we find 'explodasaurus,'" he says. The team may find many broken bone pieces spread across a hillside. Then it becomes impossible to recreate the entire animal: "We have to identify the entire animal from individual pieces." Each of Hurum's expeditions also requires a lot of preparation. "We have between 15 and 20 people, tons of equipment - food, jackhammers, water," he explains. "There's a lot of work before you start the cool thing."[E] For Hurum, the "cool thing," is the act of discovery. In 2006, his team made its greatest discovery so far. After removing about 60 tons of rock by hand, Hurum and his team eventually dug out an enormous fossil. "We knew immediately this was something special," says Hurum. "The large pieces of bone ... told us that this was big." It was a plesiosaur - a prehistoric sea monster with teeth the size of cucumbers. The fossil was not complete, but it included a front flipper, a shoulder, and pieces of skull and neck.[F] For Hurum, the discovery of this 15-meter-long creature - nicknamed "Predator X" - was an amazing moment. "It's like one of those scratch-off lottery tickets every time you dig," he explains. "Sometimes, you start digging and you might just find part of a skull or other bone. Sometimes, you find the skull and the vertebra ... Then you know it's a jackpot!"What is the purpose of paragraph D?

Sam was with his housemate Dane near Belongil Beach in the Australian state of New South Wales. The waves looked good and Sam was sitting on his surfboard, waiting for the right time to begin his first attempt.[B] Suddenly, horror struck. A great white shark rose from beneath the surface and pushed him off his board with great force. Edwardes felt a sharp pain in his leg and began to scream. As quickly as he possibly could, he got back on his board and began paddling toward the beach. As he paddled toward the shore, he shouted for help and warned other surfers about the shark.[C] When he arrived on the beach, his housemate and others on the sand realized how bad the damage was. The scene was extremely frightening. The shark had bitten a large piece out of his leg and blood was spilling out quickly. The shark had also taken a large chunk out of his surfboard.[D] Fortunately, Edwardes and those around him remained remarkably calm. His housemate and others on the beach called for an ambulance and helped stop the blood flow with a number of surfing ropes. Although Edwardes was confused about what was happening to him, he stayed calm enough to thank those around him for helping him. He was soon airlifted1 to a nearby hospital.[E] After surgery lasting four and a half hours, it became clear that Edwardes had been extremely lucky. The shark had missed some of the most important arteries2 and nerves.3 Because of this, not only was he able to survive, but there is a good chance that he will be able to surf again in the future. 1 To be airlifted is to be transported by airplane or helicopter. 2 An artery is a tube in the body that carries blood from the heart to other parts of the body.3 A nerve is a part of the body that sends messages between the brain and other parts of the body, allowing for movement and feeling.In paragraph A, the word housemate means ________.
