Answer:
22 mu
Explanation:
Since maximum number of flies are observed with +pb and s++ phenotype, they are the parental combinations.
Minimum number of flies are observed with +p+ and s+b phenotype hence they are the result of double crossover.
Gene order would be +bp and s++ since it is the only case which would lead to production of above mentioned double crossover. Hence gene b is in the middle of genes s and p.
Single cross over between genes s and b will give progeny +++ and sbp.
Map distance between s and b loci = recombination frequency =
(number of recombinants/ total progeny)*100
= [(single cross over between s and b + double crossover)/total progeny]*100
= [(102+106+7+5/1000]*100
=(220/1000)*100
=0.22*100
=22 mu
Answer:
Accuracy
Explanation:
In science, accuracy describes closeness to the actual value, rather than precision, which describes closeness to your own experimental values.
In mathematics, deviation best describes variation from the actual value to the observed value.

Answer:
Because the leading strand is synthesized continuously while the lagging strand is discontinuously synthesized.
Explanation:
Two DNA strands have opposite polarity, that is, the 5' end of one strand lies opposite to the 3' end of the other strand. However, DNA replication can occur in 5' to 3' direction only since the formation of phosphodiester bonds require the presence of nucleophile 3' OH to attack the 5' phosphate of an incoming deoxyribonucleotide.
The problem is solved by the synthesis of the leading strand continuously and the synthesis of the lagging strand in a discontinuous manner. Lagging strand synthesis requires the formation of primers and their elongation to form Okazaki fragments that may have few hundreds to few thousands of nucleotides. Removal of primers from Okazaki fragments is followed by joining them together to make the long lagging strand. The discontinuous replication of the lagging strand makes the replication at the leading strand ahead of it.

The net result of excretion of H+ in the urine is the __conversion of CO₂ to H₂CO₃__ within the blood.
Explanation:
Excretion of H+ ions from the blood via urine means decreasing the H+ content in the blood. This consequently means the blood pH rises ad becomes more basic (remember H+ ions are responsible for acidity for a solution). For the body to maintain the homeostatic pH of between 7.35 and 7.45, the carbonic anhydrase activity will increase hence dissolving more CO₂ into the blood plasma to form carbonic acid (H₂CO₃). Carbonic acid dissociated fast into H⁺ and HCO₃⁻. The H+ from the dissociation replenishes the H⁺ to the right concentration.
