Which of the following areas would have to be radiographed in order to demonstrate the sphenoid strut? a. base of the craniumb. sella turcicac. middle eard. orbit

D. Orbit

Explanation:

The orbit is the cavity or bony socket of the skull in which the eye and its appendages are situated, it may also include the contents of the socket. The sphenoid bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front.

At the apex of the orbit, next to the optic foramen is part of the sphenoid bone called the sphenoid strut.

Therefore the spheroid strut can be radiographed from the orbit as it is behind it.

the answer is b

explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
