Explanation:
(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line
(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards
(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move
(4) I think it's both Newton's second law and third law motion.
I hope these helps
Answer: Option A) emulsification of lipids
Explanation:
Since the gall bladder has the sole responsibility storing bile produced by the liver, which is necessary for the digestion and absorption of lipids in the duodenum, its absence would hinder lipids breakdown, and might results in health risks
Depolarizing urges release Ach from the nerve ending, which diffuses across the neuromuscular junction. At the muscle membrane, Ach attaches to receptor sites. As sodium channels begin to open, ions cross the membrane. Also, the action potentials are then elicited.
