For the retinal cancer retinoblastoma, the inheritance of one mutated copy of rb1 from one of the parents is often referred to as a mutation that produces a "dominant predisposition to cancer." this means that the first mutation does not produce cancer but makes it very likely that cancer will develop. part c using rb1+ for the normal wild-type allele and rb1 for the mutant allele, identify the genotype of a cell in a retinoblastoma tumor. o rb1+ rb1+ o rb1+ rb1- orbi rb1- submit request answer part d what is the genotype of a normal cell in the retina in a person who has sporadic retinoblastoma? o rb1- rb1- o rb1+ rb1 o rb1+rb1+ submit request answer part e what is the normal cell genotype if the person has hereditary retinoblastoma? o rb1+rb1+ o rb1- rb1- o rb1+ rb1- submit request answer part f explain the reason for the difference between the genotypes. drag the terms on the left to the appropriate blanks on the right to complete the sentences. reset two functional rb1 genes the difference is that all cells of the person with start out with sporadic retinoblastoma one mutant rb1 and one wild-type rb1 : only those cells that suffer mutations in both rb1 genes lead to tumor formation, and those mutations are rare events. this differs in the individual with because all of their cells start out with : any cell that hereditary retinoblastoma undergoes a mutation to the single wild-type gene leads to tumor formation. submit request answer

According the inverse square law, doubling the distance from the source of the sound, a speaker, for example, will drop the sound 6 db each time. if you were standing in the back of an auditorium, 32 feet away from a speaker not using any amplification, would you be able to hear a speaker clearly? why or why not?
