This lesson discussed the engineering design process and the devastation of three ecosystems: the Kitakami River region, the Abukuma Highlands, and Japan's coastal habitat. In this activity, you will select one of these ecosystems and follow the steps of the engineering design process to design a recovery solution. Complete each section of the Recovering Ecosystems Worksheet, including the problem, sub-problems, criteria and constraints, and proposed solutions for ecosystem recovery. Instructions for each section are included in the worksheet. Be sure to review the assignment's rubric before completing and submitting this assignment. Thank you for your help

Approximately 90% of all cases of polycystic kidney disease are inherited in an autosomal dominant fashion. the disease is typically related to mutations to genes (pkd1 and pkd2). pkd genes can be found on chromosome 16. the disease occurs in approximately 1: 800 to 1: 1000 people. here is a hypothetical example. the dominant allele d will cause the development of pkd. the recessive allele is known as d. what genotypes would correspond to suffering from pkd? dd, dd what genotypes would correspond to being normal (not suffering from pkd)? dd consider that 1: 1,000 people have pkd in your population of 325million. consider that pkd is inherited in an autosomal dominant fashion. show you math for all of the following questions: what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is p? what is q? how many people in your population would have pkd?

Amarine ecologist has constructed the conceptual model shown in the diagram. what predictions can be made from using this model? where the tertiary consumers get their energy how often primary producers are able to reproduce when bacteria and fungi initiate the process of decomposition whether other secondary consumers are present
