The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect. 
 
        
             
        
        
        
The nurse should include in their discharge notes to the couple the different ways they may access to guarantee birth control.
They may continue to use barrier methods which are the most safe when it comes to not disturbing any hormonal balance or intervening with the milk. Condoms for men are usually the most easily accessed to.
Besides the barrier methods, there are also the hormonal methods. When breastfeeding these are not the most used methods. There is a special pill, progestin-only pill, that is the most appropriate because it doesn't affect milk supply when taken after 6 to 8 weeks after the birth. All hormonal methods should be taken always when counselled with the doctors. 
        
             
        
        
        
INCOMPLETE DOMINANCE INHERITANCE:
<span>5.  In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.  These genes, however, show incomplete dominance.  The heterozygous (BB') condition results in blue plumage.  List the genotypic and phenotypic ratios expected from the following crosses:  a) black x blue  b) blue x blue  c) blue x white</span>
<span>6. </span><span>In snapdragons, petal color is determined by a single gene locus with two alleles making the "red" allele (R) incompletely dominant to the "white" allele (r).  Heterozygotes have petals, which are neither red nor white, but pink.  a) If a true-breeding red flower is pollinated with pollen from a white flower: What fraction of the seeds (F1 generation) would be expected to produce red-flowered plants?  What fraction of the gametes produced by the F1 plants would be expected to bear the R allele?  b) If two pink flowered plants are crossed, what genotypic and phenotypic ratios are expected among the offspring (F1 generation)?</span>
