Fluoxitine is given to a client at a dosage of 500 mg every 6 hours. Assuming that the half-life of this drug is 3 hours, at wha
Ber [7]

Answer:

The correct answer would be - 9 hours.

Explanation:

The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.

At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.

Thus, the correct answer is : 9 hours.

1. The following statement is similar to those you might see on exams. Write a paragraph of 3-5 sentences describing 1) whether
yanalaym [24]

Answer:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it  indicates  low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb,  decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and  favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules  binding by Hb, and easy release to respiring cells.

Murljashka [212]
  • Total displacement=6800m
  • Time=2h=7200s

\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}

\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}

\\ \sf\longmapsto Avg\: Velocity=0.9420m/s

Why did the invention of pcr make dna fingerprinting possible
Svetlanka [38]
Answer:

With the invention of the PCR technique , DNA profiling took huge strides forward in both discriminating power and the ability to recover information from very small or degraded starting samples.

The process of PCR mimics the biological process of DNA replication but confines it to specific DNA sequences of interest.

In PCR process , the DNA sample is denatured into separate individual polynucleotide strands through heating. Two oligonucleotide DNA primers are used to hybridise to two corresponding nearby sites on opposite DNA strands. Thus two new copies of the sequences of interest are generated.

Repeated denaturation , hybridisation and extension in this fashion produce an exponentially growing number of copies of the DNA of interest.

Quantitative PCR methods enable automated , precise and high - throughput measurements.
