Question: You are given a new situation: Two neighboring towns had different demographics. Hill town had younger inhabitants, most of them in their 30's and 40's. Lake town was inhabited by elderly people, most of them above 65 years of age. and a hint : Old age begins in the mid-60s and lasts until the end of life. Most 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. Please answer this question : Which town had fewer people that have retired from work?
Answer: Hill

Question: You are given a new situation: David wants to revisit the theory of evolution proposed by Darwin and Wallace. He is particularly interested in two species of deer, species A and species B. Species A has some helpful traits, but species B has some harmful traits. He is planning to write a paper on why some species are greater in number while others are smaller in number. and a hint : The theory of evolution by natural selection was proposed at about the same time by both Charles Darwin and Alfred Russel Wallace, shown in Figure below , and was set out in detail in Darwin's 1859 book On the Origin of Species . Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits, or traits that are not helpful or advantageous for survival to become more rare in a population of organisms. This occurs because organisms with advantageous traits are more "fit" to survive in a particular environment and have "adapted" to the conditions of that environment. These individuals will have greater reproductive success than organisms less fit for survival in the environment. This will lead to an increase in the number of organisms with the advantageous trait(s) over time. Over many generations, adaptations occur through a combination of successive, small, random changes in traits, and natural selection of those variants best-suited for their environment. Natural selection is one of the cornerstones of modern biology. Please answer this question : Would species B's traits be more or less common than species A's?
Answer: less

Question: You are given a new situation: George builds a fence in his back yard and plants a vine next to it. As the vine grows it comes in contact with the fence. and begins to grow wrapping itself around the fence. Once it reaches the top of the fence its growth stops. and a hint : Plants also have a touch response called thigmotropism . If you have ever seen a morning glory or the tendrils of a pea plant twist around a pole, then you know that plants must be able to sense the pole. Thigmotropism works much like the other tropisms. The plant grows straight until it comes in contact with the pole. Then, the side of the stem that is in contact with the pole grows slower than the opposite side of the stem. This causes the stem to bend around the pole. Please answer this question : Given a plant comes in contact with an object while growing, will it stop growing or grow at a different angle?
Answer:
different angle
