Answer:
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.
<em>An internal structure called liver is present in frog same as human beings. </em> The liver releases chemical called bile that are utilized in digestion of fat and then emptied into the small intestine.
Hence, skin and liver are important for the survival of frog.
Answer:
Type IIA- Fast twitch, fatigue resistant unit
Explanation:
During intense activities such as exercises where there is an increase in the contractile muscle strength, there is an activation of additional muscles to accomplish the task.
This is referred as motor unit recruitment.
It can be type I where it involves slow twitch fatigue resistant units with small twitch tension and slowest contraction
Or Type II A- where fast twitch, fatigue resistant fibers are activated to enable a larger force and faster contraction.
