Answer:

he Taeniae coil

Explanation:

The mesocolic,free and omental taeniae are collectively known as TAENIAE.

HURRY PLEASEEEEE I WILL NARK BRAINIEST
postnew [5]
Here are two negative impacts of runoff:
1) Runoff can cause erosion
2) Runoff can carry contaminated water (ex: Waste from a farm) into rivers and streams

What happens during the process of transpiration is a plant absorbs water through its roots and then gives off water vapor through the pores in its leaves.
