<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.
Answer:
If bird song promotes an individual's ability to attract a mate and reproduce, then the song has an <u> function</u>
<u />
Explanation:
Within a community, certain novel traits are fixed because they impart beneficial adaptations on an individual in their ecosystem (like mate attraction). Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.
Natural selection takes place and is determined by the fitness of an individual
, it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.
This gene could be analyzed to determine its homology level with a human gene, which then could be restored in its normal expression. This strategy can restore the normal phenotype in defective human cells.
Sequence homology, which refers to the level of evolutionary relationship among genetic or proteins sequences, is a fundamental subject matter to determine gene function.
From this approach (sequence homology search), researchers can identify valuable genes involved in diseases in which the restoration of their normal expression levels can be used to restore the normal phenotype in defective cells.
In this case, the identification of a gene in cockroaches that is responsible for nerve regeneration could be used for subsequent identification of a human homologous gene sequence, which then can be restored in order to treat human paralysis.
