Answer:

During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.

The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

A patient will be taking amiodarone [cordarone]. which baseline tests are necessary before this medication is started? (select a
olga55 [171]
Upon researching, I believe the choices are:

<span>A. Chest radiograph and pulmonary function tests
B. Complete blood count with differential
C. Ophthalmologic examination
D. Renal function tests
E. Thyroid function tests
</span>
Among these, the baseline tests necessary for the patient before taking the medication are: A. Chest radiograph and pulmonary function tests, C. Ophthalmologic examination, and E. Thyroid function tests. This is because Amiodarone has several possible toxic side effects. Some of these are thyroid toxicity, opthalmic effects, and pulmonary toxicity. Thus, it is necessary to first know the baseline of the patient for these systems and then checking if the results have deviated much after he/she takes the medication.

Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e
cricket20 [7]

Answer:

  • The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
  • According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
  • After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.
