Suppose a similar experiment was set up to measure changes in air composition immediately before and two days after
twenty potted plants were placed in a clear, sealed aquarium near a window.

How would the second row of values in the plant experiment most likely compare to the second row of values in the
original experiment?
Oxygen levels would be higher, but carbon dioxide levels would be lower
Carbon dioxide levels would be higher but oxygen levels would be lower

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.

object 2 because all the other ones are wrong

nah.   i'm just sleepy.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
