Yes.

The letters of the alphabet are really just abbreviations for the nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C)

Sindrei [870]

The answer would be: "What is your understanding of celiac disease?"

Celiac disease is one of the allergic/autoimmune diseases that need a good education to prevent recurrence. Before giving information about the disease, the nurse should obtain what information about the disease that they already know.

A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and the frequency of i allele is 0.5.

If:
$I^{A}$ - the frequency of IA allele
 $I^{B}$ - the frequency of IB allele
 $i$ - the frequency of i allele

Then:
 $I^{A} I^{A}$ + $I^{A} i$ - the frequency of individuals with A blood type
 $I^{B} I^{B}$ + $I^{B} i$ - the frequency of individuals with B blood type
 $ii$ - the frequency of individuals with O blood type

Let's first take a look on the Dunker population:
$I^{A} = 0.3$
$ii=0.16
$

Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.16}$
⇒ $i=0.4$

Now, we have the frequencies of two alleles ( $I^{A}$ and $i$ ). To calculate the frequency of $I^{B}$ allele, we will use the formula:
 $I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.3-0.4$
⇒ $I^{B} = 0.3$

Now, in the general population:
$I^{A} = 0.4$
$ii=0.25$

Similarly to the work for the Dunker population:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.25}$
⇒ $i=0.5$

$I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.4-0.5$
⇒ $I^{B} = 0.1$


b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.

How does comparative anatomy support the idea that organisms share ancestors?

REY [17]

When you compare different organisms and see that they have the same or similar anatomic traits, it's reasonable to assume the organisms share a common ancestor where they would have gotten trait from. (evolution)

one hypothesis in the barn-swallow study was that long-tailed swallows would produce more offspring than average-tailed swallows

AURORKA [14]

I think the correct answer from the choices listed above is the last option. The control group to be used to test the hypothesis would be the swallows with average-length tails. A control group is defined as the group in an experiment or study that does not receive treatment by the researchers.
