An 85-year-old woman is administered a general anesthetic for repair of a hip fracture. Which of the following properties of the

anesthetic place her at risk for respiratory depression?
Biology

Answer: Solubility in lipids

Explanation:

All the volatile anaesthetic agents has dose dependent respiratory depression VT and MV which may be compensated by increased respiratory rate.

The respiratory depression is more common in case of older people as they cannot compensate for the volume of air.

The solubility of the anesthesia in the lipids can be a risk which can put 85 year old women into respiratory depression.

Why patients with moscular dystrophy suffer from breathing and heart malfunction!?
tamaranim1 [39]
Muscular dystrophy is a muscle disease that causes a loss in muscle mass and weakness. Patients with muscular dsytrophy may experience a weakening in their cardiac muscles, causings heart malfunction. Muscular dystrophy can also deteriorate the diaphragm, a muscle that solely aids in respiration, causing a breathing malfunction.

An mRNA sequence reads: GAA/GCU/AUA/CUA/UGU. What would the effect on the amino acid be if the second codon read GCA instead, an
Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).

An owl has good night vision because its eyes can detect a light intensity as small as 5.0 × 10-13 W/m2. What is the minimum num
Lady bird [3.3K]

Answer:

Thus, the minimum number of photons per second is 77.34

Explanation:

Light intensity, I_{min} =  5\times 10^{-13} W/m^{2}

Pupil has a diameter, d = 8.5 mm

                                      = 8.5 x 10^{-3} m

Radius of the eye, r = 4.25 x 10^{-3} m

∴ Area of the eye, A = \pi .r^{2}

                                 = 3.14\times \left ( 4.25\times 10^{-3} \right )^{2}

                                = 5.6\times 10^{-5} m^{2}

Let P_{min} be the minimum number of photons.

Therefore, P_{min} = I_{min} x A

                                              = 5\times 10^{-13} x 5.6\times 10^{-5}

                                             = 2.8\times 10^{-17} W

Thus the minimum number of photons is given by

N_{min}=P_{min}/E

where E = hc/\lambda

             = \left (6.63\times 10^{-34}\times 3\times 10^{8}  \right )/548\times 10^{-9}

            = 3.62\times 10^{-19} J

Therefore, N_{min} = \frac{2.8\times 10^{-17}}{3.62\times 10^{-19}}

                                              = 77.34 photons per second

Thus, the minimum number of photons per second is 77.34
