prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

Len [333]
<span>The nurse needs to note the outburst, and report it to her supervisor. Although this comment seems at the surface to be an admission of guilt, perhaps there are other unseen circumstances. For example, perhaps she is blaming herself for letting the child out of her sight, and the injuries were actually caused by another while the child was out of her vigilance.</span>

Homework. Unanswered
Dennis_Churaev [7]

Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.

  • All bacteria indicated in the question can be classified by the Gram staining test:
  1. Actinomycetes are Gram-positive bacteria
  2. The genus <em>Arthrobacter </em>includes Gram-positive bacteria
  3. <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
  4. <em>Staphylococcus spp.</em> are Gram-positive bacteria
  5. <em>Bacillus spp</em> are Gram-positive bacteria
  6. <em>Mycobacterium spp.</em> are Gram-positive bacteria

  • Prokaryotes can be divided into two domains: Bacteria and Archaea.

  • Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.

  • In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).

  • Archaebacteria belong to the Archaea domain.
