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

Answer:
C. Mutualism
Explanation:
Mutualism is the type of relationship between two organisms in which both benefit
The answer i would pick is <span>A. the presence of glaciers thats the correct answer

Explanation:
The small intestine includes the duodenum, jejunum, and ileum.
The answer to this question would be simple squamous epithelium.
When you need to supply oxygen or nutrient, the thinner cell layer the faster it can move. In this case, simple squamous epithelium is better since it provides protection but can let the nutrient transported quickly.
