Some snake embryos have small buds resembling limbs. These buds disappear at later stages of embryonic development. What conclusion can be made about how these snakes evolved over time ? PLEASE HELP !

explanation: grsaa

a and c are the answeres

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

acceleration = 18/3 = 6 m/s per second.
