You are given a new situation: Two regions of the same country had very different climates because of the different landscapes. East region had an alpine landscape, was situated in the mountains. North region was flat and located at sea level. and a 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. Please answer this question : Which region had an alpine tundra?
Ans: East

You are given a new situation: Two farms were selling on Seattle markets. Berry farm, which used organic methods, no fertilizers and pesticides, and Rose farm, which used conventional agricultural methods, including fertilizers and pesticides. and a hint : Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick. Please answer this question : Which farm contributes more to the carrying of chemicals to nearby rivers?
Ans: Rose

You are given a new situation: Bill and Larry did some research on fungi. Larry researched saprophytic fungi, while Bill researched parasitic fungi. They later exchanged findings. and a hint : They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. Please answer this question : Which researcher learned more about fungi using enzymes to break down living tissue?
Ans: Bill

You are given a new situation: Two brothers got sick and weren't feeling well. Strangely enough they found out they were infected with viruses. Tom was infected with human papillomavirus, while Chris was infected with hepatitis. and a hint : Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and EpsteinBarr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. Please answer this question : Which brother was more at risk of developing anal cancer?
Ans: Tom
