I would say that it is important for a nurse to have a resumé as complete as possible and to show all the skills that one can do.
So the nurse should include in the skills section:
- CPR certification
- Language spoken: this would help when dealing with foreign patients.
<span>- software nursing license
</span>*Driver´s license (depending on each case, but it is not a must)

The rest of the information can be added to work experience and studies.

How would you separate a mixture of Iron filings,sand,salt an wood chips (go into detail)
anyanavicka [17]
First I would use a magnet to get the iron filings out then I would use a sieve to separate the wood chips from the sand and salt. After this pour water into the sand and salt and put it through filter paper, the salt will go through as it is dissolved in water and the sand will be left behind. Place this salt solution into a dish and put it over a flame, the water will evaporate and leave the salt behind

The northern red-legged frog, or Rana aurora, is found along the western coast from British Columbia to Northern California. The
erastovalidia [21]
I'd say that the mechanism which might keep Rana aurora and Rana boylii from mating is B. temporal isolation, since their breeding seasons do not occur at the same time.
It is not anatomical isolation, since they are both frogs. It is not geographic isolation, since they meet in California. It is not behavioral isolation since they both have breeding seasons.

1. In humans, the ability to sing well is dominant over the recessive trait of being a terrible
pickupchik [31]

The probability of Sean to both sing and dance well is 50%.

<h3><u>Explanation:</u></h3>

The gene that is dominant is expressed in phenotype of the individual and the genes are actually obtained from the parents.

Here two characters are mentioned which are singing and dancing.

The dominant character i.e able to sing is marked by gene S and the corresponding recessive allele is marked by gene s.

Similarly, the ability to dance is marked by gene D and recessive allele is marked by gene d.

So, the mother is heterozygous and she can sing well, but can't dance. So her genotype is Ssdd.

The father can't sing and is homozygous, so his genotype is ssDD.

Gametes from the mother is Sd and sd. While the gamete from the father is sD.

So the probabilities of the progenies are SsDd and ssDd.

So the probability of Sean to both sing and dance well is 50%.
