this is the equation for the formation of sodium chloride from sodium bromide. cl2 + 2nabr → br2 + 2nacl which are the reactants and the products in this reaction?
a. the reactants are cl2 (chlorine) and nabr (sodium bromide). the products are br2 (bromine) and nacl (sodium chloride).
b. the reactants are br2 (bromine) and nacl (sodium chloride). the products are cl2 (chlorine) and nabr (sodium bromide).
c. the reactants are cl2 (chlorine) and br2 (bromine). the products are nabr (sodium bromide) and nacl (sodium chloride).
d. the reactants are nabr (sodium bromide) and nacl (sodium chloride). the products are cl2 (chlorine) and br2 (bromine).

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?

Which of the following statements about archaea and bacteria is true? a. neither is single-celled. b. they both have nuclear membranes. c. neither reproduces by binary fission. d. they both lack a nuclear membrane.

Which statement best describes how the loudness of the sound affects the high-pressure region created by the sound wave? a. a louder sound has no effect on the pressure created. b. a louder sound means a high-pressure region that is higher. c. a louder sound means a high-pressure region that is not as high.
