Frogs have some important internal and external structures that helps them to survive, grow and reproduce. Frog have almost similar internal anatomy to humans.
Frogs have the ability to respire through both lungs and skin. Skin is the external structure that helps them to respire in aquatic ecology.The skins helps to dissolves oxygen from the air and water and releases carbon-dioxide. Skin helps frogs to respire under water but if water do not have enough oxygen, frogs will drown.

Answer: A.Caffeine
Explanation:
Caffeine works by blocking adenosine, a neurotransmitter that promotes sleep. This makes us feel more awake and alert. It's the most commonly used psychoactive substance and is found in many everyday items like coffee and medicines.
The actual mechanism of A) Caffeine is to block chemicals that inhibit or slow nerve activity in the brain. Caffeine functions as an adenosine antagonist, meaning it inhibits the adenosine receptors. Adenosine is a neurotransmitter that promotes sleep, so caffeine's effect reduces sleepiness and enhances alertness.
This mechanism allows caffeine to indirectly increase adrenergic activity (energy release), promoting a more energetic state. While caffeine is often associated with increased alertness and arousal, it's important to remember that it's acting primarily by blocking the inhibiting effect of certain chemicals on the brain nerve activity.
It's noteworthy that caffeine, as the world's most widely consumed psychoactive drug, is unregulated, found in everyday items like beverages and medicines, and generally not harmful in moderation.
