Please answer correctly the following question related to the paragraph below. Which group had more organisms having mutations that cannot be passed to the next generation? Dan studied multicellular organisms that presented mutations. Group A presented gemline mutations, while group B presented somatic mutations. He was fascinated by these organisms. Hint: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer.
Ans: group B

Please answer correctly the following question related to the paragraph below. Would balloon A have faster or slower inside air movement than balloon B? Bob just came from a hot air balloon ride. On his way home he saw two balloons, balloon A and balloon B. Balloon A was flat, but balloon B was inflated. He was wondering how balloons go up so effortlessly. Hint: Many people enjoy riding in hot air balloons. Some use them for romantic picnics and marriage proposals. Others race in competitions. Being above the earth gives a whole new perspective on the world around us. As the beginning of a hot air balloon ride, the balloon is flat because the pressure inside the balloon equals the pressure outside. When the air inside the balloon is heated, the speed of movement of those air molecules increases and the pressure goes up. After a while the balloon is completely expanded and the flight is ready to take off.
Ans: slower

Please answer correctly the following question related to the paragraph below. Will spending long periods of time reading or working on a computer increase or decrease your chances of becoming nearsighted? Dorian goes to the eye doctor to figure out what is wrong with his vision. Ever since he was a child things that were far away seemed very blurry to him but it didn't affect his ability to read or play with friends so it never really bothered him. After the doctor gave him an eye exam he was given a new pair of glasses to correct Hint: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school.
Ans: increase

Please answer correctly the following question related to the paragraph below. Which student read more about the mucous membrane lining the jejunum? Pete liked the human physiology so he started reading about the digestive system, especially about the jejunum. His colleague Fox, studied more about the stomach. Hint: The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court!
Ans: Pete
