The animals shown in figure 18-1 can all be categorized
as what type of animal? what trait is shared by all of these animals?

These are all vertebrates and what they all have in common is that they all have back bones! (also what makes them vertebrates in the first place aha)

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
