A rare double mutation was found to be naturally occurring in switchgrass, a grass species related to maize. The mutations lead to the overexpression of both Rubisco polypeptides and RAF . Based on the information provided, explain how the fitness of the mutant switchgrass will compare with that of a mutant switchgrass overexpressing RAF alone. The small subunits of Rubisco are encoded by a nuclear gene while the large subunits of Rubisco are encoded by a chloroplast gene. A particular maize plant has a mutation in the allele encoding the large subunit of Rubisco. Pollen from this mutant plant is used in a cross with a plant that contains the normal allele. Explain why the offspring resulting from this cross will not express this mutation.

The subject option isn't available. the topic is earth science!suppose you are a city engineer whose job it is to explore how to use more renewable energy in your locality. 1. consider the resources in your city and select one of the following: - hydropower -solar power -wind power -geothermal power 2. prepare a pamphlet or multimedia presentation to convince a committee of citizens and local leaders that the renewable energy source you have selected is best for you locality. in your pamphlet or presentation include: - a discussion of the renewable energy source that is best for your town and why -a discussion of the advantages and disadvantages of this energy source -a discussion of why you think your city should use more of this energy source -how the use of renewable energy will impact your city -pictures and/or charts and tables to strengthen your arguments

The closer the genetic link between two individuals, the greater the correspondence

Why does the blending of many different diciplines present both challenges and opportunities to enviromental scientist?
