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.

Gregor Mendel studied different genes ( corresponding to traits of pea plant) and their pattern of inheritance.
Thus, scientist used his data to conclude that traits are passed from parents to offspring through genes.
