(08.01, 08.06 HC) A group of scientists studying vegetation in a…(08.01, 08.06 HC)A group of scientists studying vegetation in a mountain range observe that a certain flowering plant grows taller at lower elevations and shorter at higher elevations. Assuming the two populations of plants are genetically similar, those height variations are most likely due to developmental flexibility that allows the plants to assume tall or short growth forms. Describe three biotic or abiotic factors that could differ at high and low elevations and cause the difference in plant height.Identify the experimental procedures for this investigation. Using one of the factors listed in part (a) as an independent variable, a hypothesis that proposes how this variable could cause the difference in plant height at high and low elevations. Using seeds from this species of plant, design a procedure for a controlled experiment to test your hypothesis.Predict the results that would support your proposed hypothesis and the results that would disprove your hypothesis.Justify your prediction by providing supporting reasoning. (08.02, 08.06 HC)Despite the extremely cold conditions that lead to the formation of the ice, a huge diversity of marine life depends on the ice to exist. Microbes, including algae that live in dense mats on the underside of the ice, make up the bulk of the biomass within the ice and act as the base of the arctic marine food web (fig 1).

The sea ice extent period of record is from 1979-2020 for a total of 42 years.According to this global sea ice data, the January average arctic sea ice extent of 13.65 million square km (5.27 million square miles) was 770,000 square km (297,000 square miles), or 5.3 percent, below the 1981-2010 average. January 2020 marked the 22nd consecutive January with below-average sea ice extent (fig 2). Describe one strategy polar bears and arctic seals use to regulate body temperature and metabolism. Explain how the lack of sunlight in the winter season affects the number and size of the trophic levels in the arctic marine food web.Identify the dependent variable of the data graphed in Figure 2. Explain one way this variable affects the biodiversity of the arctic marine food web.Analyze the trend of sea ice extent before the year 2000 and the trend observed after. Describe one environmental factor that could explain the difference between these trends.Predict what will happen to the arctic marine ecosystem in the future. Provide evidence to justify your claim.
