Answer: A.  the middles of the data sets and the spreads around them should both be considered.

Explanation:

When comparing data from two different groups, the most frequently occurring values should not be removed because they are most representative of the data and so will be very important in comparing the data.

The highest and the lowest values should not be the only data considered, indeed those should be the of lower importance than the values in the middles as the highest and lowest can sometimes be outliers.

Averages are good for summaries but shouldn't be the only things considered. The correct answer is therefore the first option that the middles and the spreads around the middle should be considered as these are more indicative of the groups.

<h2>Inflammation of the pericardial sac is the process that would have occurred within the pericardium.</h2>

Explanation:

  • Post myocardial infarction (MI), pericardial inflammation or early pericarditis is a complication that usually occurs within the first 24-96 hour time period.
  • The high-pitched, scratchy, scraping sound heard with an increase in exhalation when the client leans forward is due to the increased pericardial frictional rub of the inflamed pericardial layers in the pericardial sac.
  • These heart sounds are typical of pericarditis and can be best heard during inspiration as well as forced expiration with the patient in the forward-leaning position.

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
kipiarov [429]

The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.

<h3>What is Allelic frequency?</h3>

The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.

The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:

2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.

∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.

The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.

Therefore, it is well described above.

Whales have what seem like remnants of a pelvis and femur, as shown here. What are these structures an example of?
andriy [413]
vestigial limbs

vestigial limbs are the remnants from the development of any one organism's ancestors. 

Humans, for one example, have no real need for an appendix now that we are no longer herbivores. 

Look at a x-ray image of certain snakes and you can see the structural remains of feet.
