Which of the following can be concluded based on the paragraph above?
OA. New observations about accepted theories are always disregarded by scientists
ОВ.
New observations can result in revisions to accepted scientific theories.
OC.
Scientists can change existing theories without any evidence if they think the theory is incorrect.
OD
Observations made during investigations are not used by scientists to form or revise scientific theories

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?

Recombinant dna (rdna) creates offspring which are genetically identical to the parent is the process of breeding only organisms with desirable traits involves the removal of the nucleus of a cell combines genes from organisms of different species in a lab

Hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support this conclusion?
