Which vertebrate lays its eggs on land? a. lizard b. frog c. newt d. catfish

A lizard :)

Explanation:Frogs lay there eggs in the water for example a underwater stick. Newts also lay there eggs underwater or in a underwater enviroment. And catfishes also lay they eggs under water. Where i live (Florida) there are millions of lizards and sometimes i find them on the ground or on land. I also did some research and its a fact that lizerds do in fact lay there eggs on the ground.

I really hope this helps have a great rest of your day :) :) :) :) :)

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.
