Question: The department of geriatrics conducted a study on two groups of people, group V composed of people above 65 years old, and group W which had people under 65 and many under 60 years old. They were studying the effects on aging on the human body. Which group had more people with risk of cancer? Hint: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.
Answer: group V

Question: The specialists studied two groups of larvae. Group L displayed all kinds of mutations while group D didn't. Which group of larvae had fewer hereditary diseases? 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.
Answer: group D

Question: Two meteorologists study Earth's climate. Jerry studies alpine climate, while James studies tropical climates. They both made great progress. Which person learned less about the dry adiabatic lapse rate? Hint: Alpine climate is the average weather (climate) for the alpine tundra. The climate becomes colder at high elevationsthis characteristic is described by the lapse rate of air: air tends to get colder as it rises, since it expands. The dry adiabatic lapse rate is 10 C per km (5.5 F per 1000 ft) of elevation or altitude. Therefore, moving up 100 metres (330 ft) on a mountain is roughly equivalent to moving 80 kilometers (45 miles or 0.75 of latitude) towards the pole. This relationship is only approximate, however, since local factors such as proximity to oceans can drastically modify the climate.

James
