Answer:
First, the options:
A. Midazolam
B. Ketamine
C. Nitrous Oxide
D. Bupivacaine
The ANSWER is A.
A. Midazolam
Explanation:
A. Midazolam✔
Midazolam is mainly used for amnesia or sedation in many diagnostic, therapeutic, and endoscopic activities or procedures.
B. Ketamine ❌
It has higher risk of side effects.
C. Nitrous oxide ❌
It won't be preferable for this case, since it can not be breathed in during a bronchoscopy.
D. Bupivacaine❌
This is solely for local anesthesia.

Answer:
(a) 21% of the human genome is comprised of G.
(b) 29% of the human genome is comprised of T.
(c) 29% of the human genome is comprised of A.
Explanation:
According to Chargaff's rule, a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G), and G pairs with C and A pairs with T.
If 21% of the genome contains C, then 21% also contains G.
Therefore 21% + 21% = 42% of the genome is comprised of G+C.
The other 58% is comprised of A+T, and because they pair with each other, 29% will correspond to A and 29% will correspond to T,
Answer:
Enhancement in the life expectancy of humans can exhibit certain unwanted outcomes that could affect the quality of life. Some of the probable social and ecological outcomes due to an increase in life expectancy are:
Social: Greater life expectancy would signify that the age of employment would get extended. As an outcome, the older individuals would hold the seats for a longer duration, leaving only some seats for the young. This would influence the life quality and development of the young.
Due to the increase in life expectancy, there would be an elevation in the demand for basic needs, and increased consumption of food increased utilization of land, and larger population. The use of global resources would increase by humans, therefore, declining the resources at a greater rate. Hence, overall, the ratio of the old to the young would get influenced, and therefore, the quality of life would get affected.
Ecological: With longer life expectancy, there will be an enhanced burden of human species on the planet Earth. Due to this, the balance between the humans and the other species would get disturbed. Human activities have been substantially related to the issues of global warming, issues of deforestation, endangering of other species resulting in ecological imbalance.
Enhancement in the life expectancy of humans would cause further destruction of endangered species and huge imbalance in the ecosystems that would eventually influence life of human beings. Therefore, ecological in combination with socioeconomic influence of greater life expectancy incline towards reduced quality of life, and it is not desirable.
