Describe the phenotypes of the following E. coli mutants when grown in two different media: glucose only and lactose only. Explain why. (6 points) a. A strain with a mutation in the gene encoding the lacI gene; the mutant LacI protein cannot bind allolactose. b. A strain with a mutation in the gene encoding CRP; the mutant form of CRP binds but cannot release cAMP. c. A strain in which the Shine-Dalgarno sequence has been deleted from the gene encoding adenyl cyclase.

enzyme speed up the reactions

it should be briana that has it to me

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
