Serpentine soils are a particular soil type dominated by an elevated concentration of certain ions andmetals. It is distributed in a meandering fashion (giving it its name), with abrupt boundaries to themore typical sandstone soils. The high concentration of these metals is generally toxic to manyplants. However, populations of Leptosiphon parviflorus with pink flowers have managed to grow andreproduce on these serpentine soils in northern California. In addition, L. parviflorus plants with whiteflowers and separated by only a few meters occur on the sandstone soils.You performed an experiment that measures differences in survival (fitness) when seeds fromsandstone and serpentine soil are grown in both environments.

Question

Serpentine soils are a particular soil type dominated by an elevated concentration of certain ions and
metals. It is distributed in a meandering fashion (giving it its name), with abrupt boundaries to the
more typical sandstone soils. The high concentration of these metals is generally toxic to many
plants. However, populations of Leptosiphon parviflorus with pink flowers have managed to grow and
reproduce on these serpentine soils in northern California. In addition, L. parviflorus plants with white
flowers and separated by only a few meters occur on the sandstone soils.
You performed an experiment that measures differences in survival (fitness) when seeds from
sandstone and serpentine soil are grown in both environments. The results from this experiment are
presented in this graph:

Explain why you cannot conclude from this graph that the observed flower color differences in
nature are under genetic or environmental control. What would you need to know in order to draw
such a conclusion?

SimpLENI will be competing in a Lugaw Cooking Competition in May. She will be using onions as a special ingredient and garnish in her recipe. She then planted onions in two soil treatments labelled as ANGAT and UNITY. After a week, SimpLENI noticed that her onions in ANGAT increased in number compared to that of onions in UNITY. She then hypothesized that the soil treatments affected the cellular division in the roots of onions contributing to the difference in yield. To prove this, SimpLENI prepared longitudinal sections of onion root tips. Support SimpLENI in her experiment and win the competition by answering the following questions:
Roscroot (Sedum integrifohum) is an herbaccous plant species that is found on limestone cliffs in southeastern Minnesota and westem New York. and on rocks slopes at high elevations (3,000 m. or - 10.000 At) in Colorado. In Minnesota and New York. the plants are sprawling and have -drooping leaves, whereas in Colorado the plants are erect and hold their caves upright. a. Briefly describe a study that vou could do in order to determine if the differences in plant morphology observed in these populations of roscroot are genetically based or due to environmental factors and describe the results that would allow vou to conclude that it is heritable.
