Explain their responses in relation to being a modular or unitaryorganism.arrow_forwardClausen and colleagues proposed two hypotheses to explain this variation within a species: (1) There are genetic differences between populations of plants found at different elevations. (2) The species has developmental flexibility and can assume tall or short growth forms, depending on local abiotic factors.

- Q6.9. Consider the following hypothetical scenario: An ancestral species of duck had a varied diet that included aquatic plants and terrestrial plants and insects. These ducks spent time on both land and water. Individuals of this species varied in the amount of webbing in their feet, with some individuals having more webbing and some having less. As many years went by, the environment changed such that the aquatic food sources were much more plentiful than those on land. Many generations later, almost all ducks had more webbing on their feet. How is this best explained? Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. The more they used their feet, the more webbed their feet became, so they got enough food to survive and reproduce. Due to chance mutations, all the ducks' feet in the next generation had more webbing. They were therefore able to eat aquatic plants and get enough food to survive and reproduce. Ducks with more webbing were better…arrow_forwardDescribe and assess several ways in which high-inputindustrial agriculture can be beneficial for the environmentand several ways in which it can be detrimental.Now suggest several ways in which we might modifyindustrial agriculture to reduce its environmentalimpacts.arrow_forwardActivity 18.5 Answer open ended statements.
