I have no idea how to get the volume

This example the answer is 3.6 mL

Explanation:

To calculate the volume you will take the final volume - initial volume.

This example final volume = 37.2 mL, initial volume = 33.6mL

Volume of sample = 37.2 - 33.6 = 3.6 mL

Do the same procedure for the other volumes.

idk

explanation:

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
